Tessa's Recipe Rundown...

Taste: Ultra chocolaty! I doubt any kids would guess there’s a vegetable involved here.
Texture:  Rich, fudgy, and moist.
Ease: Super quick and easy. No mixer, no assembling, no decorating.
Pros: Simple summer treat!
Cons: None 🙂
Would I make this again? Absolutely, all season long.

We’re about to head into the height of zucchini season which I’m so excited about!

I love getting fresh zucchini from the farmer’s market all summer long. It’s one of those veggies that’s so easy to cook and bake with. You can find a million ways to get creative whether you’re going savory or sweet. And it doesn’t take nearly an hour to cook like root veggies.

Zucchini Cake with Chocolate and a simple icing on top

Adding zucchini into cake happens to be one of my favorite ways to use the stuff.

I love snack cakes like this recipe because’ they’re just one layer and there’s no assembly or decorating required. They’re also super easy to transport. You don’t even need an electric mixer for the batter or the icing here.

That makes this recipe perfect for bringing to a summer potluck or BBQ. Especially if you have an abundance of zucchini to use up!

Easy Chocolate Zucchini Cake cut into squares

I find many chocolate zucchini cakes to be kind of bland and a little dry. Read my tips below for getting a super rich and fudgy cake with tons of chocolate flavor.

How to Make Moist Chocolate Zucchini Cake

Cocoa Powder in Chocolate Cake

Cocoa powder lends more chocolate flavor than melted chocolate. But it can also zap some moisture, so read my tips below for how to make sure your cake is nice and tender and moist. This recipe uses natural unsweetened cocoa powder (not Dutch process cocoa powder). Learn more about cocoa powder here.

For best results, weigh your cocoa powder and flour to ensure you don’t over measure. This will result in a dry cake. If you don’t have a digital kitchen scale, then use the spoon-and-level method.

How to Prepare Zucchini for Cake (IMPORTANT!)

To avoid gummy, dense, or unbaked cake it’s important to remove as much excess water from the zucchini as possible.

Start by washing the zucchini and trimming the ends. Grate using the big holes of a box grater. Scoop up the shredded zucchini and place in a strainer or colander. Move on to prepare the rest of the ingredients and batter for the recipe.

Once you’re ready to add in the zucchini, wrap it in a clean towel or paper towels and give it a very tight squeeze with your hands to wring out excess water. Do this a few times. If your hands aren’t quite strong enough you can also press the zucchini inside a potato ricer or hand held citrus squeezer. This is super effective at getting rid of water.

Once you add the zucchini to the batter, stir gently until JUST combined. Over-mixing can cause tough or gummy texture.

Why use butter AND oil in a cake?

I find this provides the best of both worlds. You get the wonderful flavor from the butter and the moist texture from the oil. This is because oil is a liquid at room temperature so it gives your palate the sensation of moisture. If you don’t have oil you can use 1 stick (113 grams) of butter for all the fat in the recipe.

How to Bake a Moist & Fudgy Chocolate Cake

In addition to the tips above, using ingredients like brown sugar, full fat sour cream, and an extra egg yolk all help to add richness and moisture to this cake. That’s because these ingredients both tenderize and draw and hold onto moisture. You can learn more about how baking ingredients work in my Magic of Baking online class.

Can I substitute the sour cream?

You can use full fat plain yogurt instead!

Metal vs. Glass Baking Pans

This recipe is best baked in an 8-inch metal baking pan. Metal conducts heat more quickly and efficiently than glass or ceramic so you won’t have any issues with an under-baked center. If you must use glass or ceramic, reduce the baking temperature to 325°F and increase the baking time by 5 to 10 minutes.

Can I double this recipe?

Yes! Double all ingredients and bake in a 9 by 13-inch pan and add about 5 to 10 minutes to the baking time. If using glass see note above.

How to make
Easy Chocolate Zucchini Cake

Yield: 9 cake squares
Prep Time: 20 minutes
Cook Time: 30 minutes
Ultra rich, moist, and fudgy Easy Chocolate Zucchini Cake is the perfect summer treat for any chocoholic and can be made in less than 1 hour! No mixer required. Tons of chocolate flavor!

Ingredients

For the cake:

  • 1 cup plus 2 tablespoons (143 grams) all-purpose flour, measured correctly
  • 1/2 cup (43 grams) unsweetened cocoa, measured correctly
  • 1 cup (200 grams) light brown sugar
  • 1 teaspoon salt
  • 1 teaspoon baking soda
  • 4 tablespoons (57 grams) unsalted butter, melted
  • 1/4 cup fresh vegetable oil
  • 1/2 cup (120 grams) full fat sour cream or plain whole milk yogurt, at room temperature
  • 2 large eggs plus 1 egg yolk, at room temperature
  • 2 teaspoons vanilla extract
  • 1 cup (136 grams) shredded zucchini, from about 1 medium zucchini
  • 1 cup (170 grams) semisweet chocolate chips

For the icing:

  • 1/2 cup (63 grams) powdered sugar, sifted
  • 1 tablespoon milk

Directions

Make the cake:

  1. Preheat the oven to 350°Line a 8 by 8-inch metal baking pan with parchment paper then spray with nonstick cooking spray. If using a glass pan, heat the oven to 325°F.

  2. In a large bowl, whisk together the flour, cocoa, sugar, salt, and baking soda.
  3. In a small bowl whisk together the melted butter, oil, sour cream, eggs, egg yolk, and vanilla extract.
  4. Make a well in the center of the dry ingredients and pour in the wet ingredients. Stir until a few streaks of flour remain. Squeeze out any additional moisture from the shredded zucchini before adding to the batter. See recipe post for tips on reducing excess moisture, which will create a gummy cake texture. Add in the chocolate chips. Stir until just barely combined.

  5. Pour the batter into the prepared pan and bake for 30 minutes (35 to 40 minutes if using glass) or until a cake tester comes out clean. If your cake sinks slightly in the middle, that's normal because it's so moist and rich!

  6. Let cool completely.

Make the frosting:

  1. In a medium bowl stir together the sugar and milk with a fork until smooth and thick but pourable. Drizzle all over the cake. Let set before serving.
  2. Cake can be stored in an airtight container at room temperature for up to 4 days.

    I often have shredded zucchini in the freezer. Based on your description, it sounds like it wouldn’t be usable in this recipe. Any thoughts?

    • #
      Tessa Arias — June 26, 2019 at 5:39 pm

      I would thaw and then *really* try to remove as much excess moisture from the zucchini as possible before baking with it!

    This recipe is amazing. The cake is moist, rich, and flavorful. I didn’t even have to put the icing on as there was enough deliciousness in the cake itself! So easy to make and will be baking again!

    I just made this today!!! I’m pregnant and had a chocolate craving after seeing this on Tessa’s Instagram earlier in the week. The recipe is pretty easy to make. We julienned and chopped our zucchini since we don’t have a grater…hah!!

    I had to bake for about 35 minutes instead of 30 minutes, however I may have sent my temperature slightly under 350°, since my oven usually runs hot.

    Overall, easy recipe and REALLY tasty!

    If you love CHOCOLATE you will love this! It is very good tasting, moist, and easy to make! But man is it CHOCOLATE! You will need a glass of milk or some ice-cream to help calm down all that CHOCOLATE flavor!

    Soooo incredible. So moist and satisfying. Plan a double batch. This will now be my chocolate go to! And because it’s got zucchini in the batter there is zero guilt. Lol. Baked 15 squares using the Pampered Chef 12 square baking pan (baked 8 minutes). This is now at the top of my favorite Tessa recipes.

    Alan Morlan — August 3, 2020 at 12:16 pm

    This is probably a rookie dumb question, but…can i cheat and use the zucchini noodles available at the grocery store? Maybe cut them into pieces?

    I just made 2 batches of this, one original and one with the adjustments I have to make for myself. Needless to say the original turned out a lot prettier, with that lovely shiny top and super moist center. Once baked you can’t see or taste the zucchini anymore, which is great if you have kids. My husband made me pack some for his hiking trip tomorrow. My adjusted one was still great for a gf/df/sf cake, but the original is basically a brownie.

    This recipe was so easy to follow and turned out great! The cake was really light and moist, and the water drainage tip worked super well in preventing it from becoming gummy.

    Jo — August 5, 2020 at 7:30 pm

    I’m always looking for ways to use zucchini this time of year. I have to say this one’s a KEEPER. Not too sweet with lots of chocolate flavor. The ULTIMATE Zucchini Cake!!!

  27. #
    Kerry Salatino — August 6, 2020 at 2:40 am

    This was OMG delicious and the best I have EVER made….definitely squeeze the zucchini as Tessa instructed! I only had one zucchini and it was enough for 1C.

    Maria Janowiak — August 6, 2020 at 7:56 pm

    Very easy, delicious, and moist. A little too moist in the middle, but that was my fault. Be sure to cook it long enough!

    I actually made this gluten-free and dairy-free and it came out amazing!!! (Sorry for substitutions– I wasn’t sure how it was going to come out because I know this can change the outcome of a recipe a TON but I wanted to share in case others were gluten-free and dairy-free and wanted to try!) I used gluten-free measure for measure flour, dairy-free butter and substituted dairy-free yogurt for the sour cream, all in the same quantities listed. I can’t believe how great it turned out– the texture is amazing! And so easy to make! Will definitely make this again.

    This is one of the best chocolate cakes I have ever tasted. It has intense chocolate flavor and depth and is moist and slightly fudgey. I like the glaze but after a couple of days it melted into the cake. This will now be my go-to chocolate cake recipe.

  59. #
    Gwen Orel — August 12, 2020 at 3:24 pm

    First recipe I’ve made here won’t be the last! Very straightforward and came out just like the picture. I withdrew one star because I just have to save five stars for favorite recipes of all time LOL But NOT because there were any flaws here. Took a little longer to bake than it said but very nice. I’ve never baked using zucchini before so was nervous but it gave it a nice almost coconut flavor. Yum!

  60. #
    Safia — August 12, 2020 at 8:51 pm

    I made this cake for the August Baking Challenge. This cake was SUPER easy to make and was so soft, chocolatey, and slightly dense. I promise, you won’t even taste the zuchinni. I guess if you were really looking, then the most “vegetable” flavor you would get would be a faint aftertaste. But honestly, who’s *really* looking for vegetables in their dessert? Especially when you have chocolate cake that looks THAT good?!

    Amazing. So moist and flavorful. I realized after I started that I didn’t have vanilla extract. I substiuted with equal parts of rum and added some rum to the glaze. So tasty!

    Baked this moist chocolate cake last week. An amazing way to incorporate vegetables into a cake. The zucchini, oil and yoghurt make the cake super moist and juicy! One of the best chocolate cake recipes I’ve tried and trust me you won’t taste the zucchini! Do try this recipe if you’re looking for a moist chocolate cake!

    Good chocolate flavor and very easy to make. I used a food processor shredding blade and the zucchini was ready in a jif. We ate it as dessert but I wuld totally eat it for breakfast. It’s not covered in frosting so not super sweet. Great with a cup of coffee.

    This cake has a great chocolate flavor and is super tasty even without the icing. I made this in a 9” round pan because we didn’t have a square pan and we ended with some leftover batter so we made two cupcakes with the leftover. DELICIOUS! What’s great is that there’s zucchini so you’re getting in your veggies 😉
    no guilt

    My frosting wasn’t as thick or pretty but as you say, not a beauty contest!

    Marie — August 18, 2020 at 6:03 am

    Made this for the first time and was really impressed. Perfect texture, crumb and taste will make it again.

    Emily Leishman — August 18, 2020 at 11:07 am

    This was incredible! So rich and moist and chocolate filled! I loved the addition of the chocolate chips! And the glaze was so pretty and perfect! Mine did soak into th cake though, so I would make sure you put it on only a few hours before serving

  92. #
    Jill — August 18, 2020 at 1:04 pm

    This recipe is worth every star there is! I measured by weight so the batter was perfect- I only have ceramic and glass to bake in though so it took a frustrating extra 10 minutes to find success! Seriously considering updating my bakeware for your recipes Tessa!

  93. #
    Kira Olsen — August 18, 2020 at 2:24 pm

    Very rich and moist! Definitely a keeper. It’s so good on its own, it doesn’t even need the icing, imo.

  94. #
    Jennifer — August 18, 2020 at 3:32 pm

    Super fudge and moist!! Will definitely make this again. Even my picky teenager had seconds!!

    Mary Perez — August 18, 2020 at 4:06 pm

    This cake is so delicious! Chocolate loaded and moist.

  96. #
    Elaine — August 18, 2020 at 5:44 pm

    I made this cake and used Truvia Brown Sugar & Fat Free Greek Yogurt. My husband diabetic and can’t have a lot of sugar. It turned out sooooo good you would never know. Thank you so much for this recipe! I am on WW too and am watching not to eat too much sugar. If you wanted to go further, you could use the sugar free chocolate chips and apple sauce in place of the oil. I will try that another day, but for now the cake was gone within 2 days!!!

  97. #
    Lori — August 19, 2020 at 6:34 am

    Made this on a whim last week to use a monster zucchini. Everyone loved it! Even zucchini haters asked for seconds – we didn’t tell them the “secret” ingredient! LOL Even without the icing, it was fantastic. Having my 4 year old granddaughter help me make a double batch today!

  98. #
    Cindy Marimon — August 19, 2020 at 10:44 am

    So moist and delicious! A great way to put some veggies into sweet treats. Will definitely make again 🙂

    Abiola Olawepo — August 19, 2020 at 1:46 pm

    Eating your cake and having it is a possible with this recipe as its loaded with zuchinni but you can hardly see or taste it. It’s one of my go to recipe when I want to impress anyone especially for the first time. Moist, delicious and healthy, all in one cake.

  100. #
    Jensen Luciani — August 19, 2020 at 8:39 pm

    Super moist, easy and delicious! Will definitely make this again!

    Cheryl — August 19, 2020 at 9:16 pm

    I followed this recipe exactly with the instructions for a glass pan. It is deliciously chocolate and very moist. It rose higher in the pan than it appears in the photo here. I perfect slice of snack cake. Thank you!

  102. #
    Chrysta Hiser — August 20, 2020 at 11:59 am

    This recipe is a keeper! It was so easy and turned out delicious. Everyone loved it. I will be making this again for sure!

  103. #
    Aaron Macpherson — August 21, 2020 at 6:22 am

    This was phenomenal! So much better than the chocolate zucchini cake I’ve been making for years. My new “go-to” recipe! Definitely making this again the next time I have a potluck or something.

  104. #
    Mallory Z. Skwiat — August 21, 2020 at 9:36 am

    Holy cow… this cake is not only easy, but is so good! Make sure you really wring out the zucchini but other than that I CANNOT wait to make this recipe again! Thank you!

  105. #
    Lotte — August 22, 2020 at 8:17 am

    Wow! I just made it and it was delicious! My little sister doesn’t really like zucchini, but now she can’t stop eating it!! I will definitely make it again;) Thank you very much for this good recipe!

  106. #
    Mallory Jurik — August 22, 2020 at 3:32 pm

    Has a great dark chocolate flavor. The zucchini makes this cake extra moist!

  107. #
    Mae — August 22, 2020 at 4:33 pm

    This cake is so chocolatey and moist, you won’t even taste zucchini. A must for any chocolate lover!

  108. #
    Sandra D — August 22, 2020 at 6:10 pm

    Tessa’s description is absolutely correct. This cake is ultra rich, moist, fudgy and most of all delicious. Recipe was easy to make and is a great way to sneak a little veg into a wonderful dessert. The tipi about squeezing the water from the zucchini with a potato ricer is genius. I feel this cake would be best served with an ice cold glass of milk or even better yet a scoop of vanilla ice cream. A definite winning recipe.

  109. #
    Allison — August 22, 2020 at 6:27 pm

    Deep chocolate taste and very moist. I now understand why to use a fork for drizzling. Get the milk ready for this one.

    @allovesbikes

  110. #
    Monica Prudencio — August 23, 2020 at 5:31 am

    This recipe was exactly as advertised! It was incredibly easy to put together and came out moist, fudgy, and rich. The second day was just as good! I had to cook it a few extra minutes but I often find that to be the case so I think it’s just my oven. I would make this again!

  111. #
    Mo Oshodi — August 23, 2020 at 8:20 am

    First time I baked a zucchini chocolate cake and its really delicious.

    The cake was moist, sweet, love the chocolate taste plus it’s a healthy cake .

  112. #
    Mike Gilson — August 23, 2020 at 9:21 am

    The Chocolate Zucchini Cake came out super moist and not unbaked, and not gummy. Was a big hit at the tiny, socially distant fire pit gathering I brought them too. Super tasty!

  113. #
    Michelle — August 23, 2020 at 11:17 am

    Delicious, easy cake recipe and rich chocolate flavor!

    A huge hit at my house. Shhhh. Don’t tell them there’s zucchini in it!

  116. #
    María Isabel Gutiérrez Rangel — August 23, 2020 at 4:36 pm

    This cake is really sooo good! Honestly, we were a bit skeptical at first about the zucchini here at home, but once we tried it we realized it really makes the cake super moist and delicious. And also, it’s so easy to make

  117. #
    Fithria — August 24, 2020 at 5:13 am

    Delicious and easy to make with the kids.

  118. #

    My family is in love with it.

  127. #
    Rae Jeffrey — August 26, 2020 at 10:46 am

    This recipe was very easy and delicious! It’s very chocolatey and rich, almost like a cross between a brownie in taste and a cake in texture. It was excellent with ice cream on top.

  128. #
    Ann — August 26, 2020 at 3:34 pm

    Very moist and fudgy. It tastes wonderful just what one needs during a chocolate craving. Will make again, and again, and again.

  129. #
    Ann — August 26, 2020 at 3:44 pm

    Quick, perfectly moist and sooooo chocolatey. Will make again but with less milk in the 1/2 cup of confectioners sugar for topping.

  130. #
    Rose Kovach — August 26, 2020 at 6:52 pm

    Very tasty!

  131. #
    Janelle W — August 26, 2020 at 7:48 pm

    I doubled this recipe in order to make it in a 9 x 13 cake pan. The cake is very bitter and dense. After looking at other recipes, the amount of cocoa in this recipe is excessive, not sure why it is so dense.

  132. #
    Laura — August 27, 2020 at 6:07 am

    This cake is moist and delicious! I would start with less milk in the icing, however. It kind of disappeared into the cake when it dried.

  133. #
    Josh Berk — August 27, 2020 at 6:58 am

    Delicious and so much chocolate!

  134. #
    Linda — August 27, 2020 at 10:22 am

    Can you use a glass pan?

    • #
      LISA W — August 29, 2020 at 3:24 pm

      Yes Linda you can just lower the temp to 325 and add 5 to 10 extra minutes..

  135. #
    Paulina Zacchia — August 27, 2020 at 1:23 pm

    I’ve made chocolate zucchini cake & zucchini brownies before, but this recipe really impressed me. It doesn’t really help much in terms of using up an abundance of zucchini, but it’s so moist & fluffy, yet rich & delicious, the small amount of zucchini used truly does seem to disappear. Speaking of disappearing, this cake was gone so fast, I wish I had made a double recipe!

  136. #
    Ruth — August 27, 2020 at 4:29 pm

    Super easy, super moist, super delicious! I used a potato ricer for drying out the zucchini and it worked perfectly. What a great way to use up extra zucchini this time of year. Will definitely make again – maybe with a little squeeze of lemon juice in the frosting too!

  137. #
    Annie Kunjara — August 28, 2020 at 4:44 pm

    Perfect amount of zucchini and you definitely need a glass of milk with the chocolatey decadence!

  138. #
    Keri Tapley — August 28, 2020 at 5:06 pm

    SO moist and delicious! A great way to use my zucchini’s from my garden. I made it twice in one month to share with my family!

  139. #
    Susana Aracena — August 29, 2020 at 9:38 am

    First time using zucchini on a sweet recipe and I loved the result. Super moist and delicious! I don’t have a square metal pan, so I used a round ceramic pan, and following Tessa’s instructions it still turned out great.

  140. #
    Miranda Ventura — August 29, 2020 at 4:38 pm

    Made this cake recently and it was super rich and moist, extra chocolatey, and has a hidden taste of zucchini and that can trick anyone! 10/10 quick and easy recipe that I highly recommend making.

  141. #
    Kate Manolas — August 29, 2020 at 4:57 pm

  146. #
    Katrin Goethals — August 30, 2020 at 9:32 am

    Used a whole egg instead just the egg yolk and dusted with powdered sugar as I don’t like icing. Very rich and chocolatey!

    This recipe is fantastic! So easy to make and it tastes like a reich and moist chocolate cake. And bonus: my family didn’t even know it had a full zucchini in the cake. Hehe!

  155. #
    Susann Pekala — August 30, 2020 at 4:54 pm

    Perfectly moist and rich chocolate flavor! Delicious and would never know zucchini is in the cake 🙂 Definitely recommend the recipe to all chocolate lovers!

  156. #
    Kimberly Dierker — August 30, 2020 at 6:33 pm

    It was very moist and I liked the bits of chocolate chips throughout! Very delicious!

  157. #
    Mandy Ding — August 30, 2020 at 10:36 pm

    This is the fourth time I’ve made the recipe. Super easy and extremely DELICIOUS! I usually make it without the frosting and it’s just as amazing as with the frosting! I store it in an lidded container in the refrigerator to keep longer and a quick reheat in the microwave makes this gooey delicious chocolate cake amazing with a cold glass of milk!

  158. #
    Linda — August 31, 2020 at 8:07 am

    This cake is so moist and delicious!! I just had to have a second piece! Quick and easy to make. I’ll be making this again!

    Cindy — August 31, 2020 at 2:16 pm

    So easy and delicious! I sprinkled a few extra chocolate chips on top before baking.

  161. #
    Eddie — August 31, 2020 at 4:43 pm

    1 cup shredded zucchini before wrenching it or 1 cup shredded zucchini after removing the water?

  162. #
    Eddie — August 31, 2020 at 9:49 pm

    So moist and tender and mouthwatering good!

  163. #
    Kam — September 6, 2020 at 3:39 pm

  164. #
    Kathy Swift — September 6, 2020 at 6:26 pm

    Turned out perfect. Doubled the recipe and added 5 eggs instead of adding egg yolks. Super moist but not dense. My family loved it!

    Trying ur chocolate Zucchini cake! I’ll let you know how it goes

  167. #
    carly Pavelchak — September 30, 2020 at 6:20 pm

    This is my third time making this cake in the last month. The first time I was supposed to give a piece to my uncle down the street and I ate it all before it got to him. The second time I made it for a party and the whole thing was gone before I could even get a slice. This time it’s allll for me and my fiancé. It is SO delicious and the icing glaze just makes it that much better. I call it our healthy chocolate cake so I’m sure we will use that excuse to make it a bunch more times.

  168. #
    JM — October 2, 2020 at 11:06 am

    You’d think this cake would be heavy and dense, it’s not at all. It’s somehow stays light and has great flavor and texture. I did add a couple of tsp of instant expresso powder to it, subbed walnuts for choc chips and used a melted a chocolate and chili bar for the icing. Superb with or without these additions I’m sure.

  169. #
    Kim Ghostkeeper — October 13, 2020 at 11:26 am

    Fabulous so good. Best cake I’ve ever made..1 substitution. Greek plan yogurt for sour cream. And chocolate cream cheese icing. Oh so good!!!

  170. #
    Sarah Duberry — October 16, 2020 at 9:07 am

    Can I freeze the chocolate zukini cake and hoe long thanks..

  171. #
    Allidah Hicks — October 26, 2020 at 2:00 pm

    The typical chocolate zucchini cake I’ve made for years was just NOT chocolatey enough. This one is FABULOUS! Since I live just west of Denver at an altitude of 5,459′, I made some adjustments. I upped the flour to 151 grams, decreased the sugar by 1 TAB, used 3 full eggs, and increased the temp to 365 degrees. It took about 38 minutes to cook. It was so yummy with just a bit of powdered sugar on top.

    I did have a question. Since I used a very large zucchini, I spooned out the seeds before I grated. When do you weigh the zucchini…before or after you press out the moisture?
