This recipe is in celebration of my NEW COOKIE coming out on September 1st, 2020! The Ultimate Cookie Handbook features over 50 cookie recipes and tons of visuals into the science of cookie baking!!
Growing up I never really liked birthday cake. Don’t get me wrong, I love a good fresh homemade cake baked with quality flavorful ingredients. But store-bought birthday cake or one made with cake mix and packaged frosting was too sweet and artificial even for my 10-year-old taste buds. And I’ve loved sweets all my life!
In fact, that weird birthday cake frosting that just tastes like sickeningly sweet plastic gives me nightmares. I used to scrape that stuff off in pure disgust. Anyone else do the same?
And then don’t even get me started on the actual bland and dry grocery store cake. And the designs and decorating… So cheesy and outdated!
This Chocolate Chip Cookie Cake recipe is perfect for those who don’t like birthday cake. Or for when you just don’t have the time and patience to bake a cake! Or maybe for those times when you just want something a little fun and different.
Whatever you do, just make sure you’re generous with the rainbow sprinkles for an extra festive cake!
I’ve formulated the chocolate chip cookie base recipe to be ultra thick, chewy, and slightly gooey in the middle with tons of flavor. The melted butter, dark brown sugar, extra egg yolk, bread flour, and cornstarch all help to accomplish this!
If you’d like to know more about the science of cookie baking, check out my free Cookie Customization Guide here. These are the kinds of details I dive into in my new cookbook, The Ultimate Cookie Handbook!
The buttercream icing for this recipe is just a half batch of my go-to Best Buttercream (the video in that post has been viewed over a million times! craziness!) but feel free to make a full batch for an extra thick layer of frosting.
For this recipe I prefer to use a springform pan because it makes it really easy to remove the entire cookie cake from the pan and place it on a pretty cake stand or serving plate. If you don’t have a springform pan, however, feel free to use a cake pan or deep pie pan. You may need to adjust the baking time.

I want to make this so bad! My brother’s birthday is coming, I’ll try and convince him to let me bake it for him (he usually wants some chocolate cake with chocolate frosting, oh well), if I can’t convince him I think I’ll just have to bake this only for myself… haha
Haha!! 🙂
When do we use the milk in the cookie recipe? I made it today and put it in at the end after I realized I had forgotten it.
The batter tastes yummy and can’t wait to bake it tomorrow!
Oops, you just add it in with the eggs. Edited the recipe to correct that error, it should be fine without it 🙂
Love your website! What can I use for a substitute for the bread flour tho?
Many Thanks,
Carol
You can just use AP flour. The bread flour helps create a nice chewy texture though, so I would recommend picking some up on your next grocery run to give it a try!
Can i replace the bread flour with just all purpose flour?
Can this recipe be adjusted for a 10″ cookie cake? If so, what adjustments would need to be made?
Is 20 min correct? I made it in a 9 in springform at 350 for about 30 min and it was a soupy mess. It would seem too thick for only 20.
That’s how long it took me to get the dough to solidify and still be slightly ooey and gooey in the middle, as you can see from the photos 🙂
All these years of baking elaborate birthday cakes and my kids finally admitted they don’t like cake. But they love chocolate chip cookies. This was a big hit. I didn’t bother to frost since I knew they would find it too sweet. Everyone loved it and the fact that it stays gooey in the middle. I’m already making it again.
Could you make this into an ice cream cake with the chocolate chip being the bottom? Would it change the cookies texture?
I made two for school get together and baked for 22 min and they still were very under baked, had to throw them away. The buttercream was really good and the cookie would have been very good if it had been baked. I would say at least 30 min bake time.
I made this for my daughters birthday. I didn’t look at the comments first that the 20 minutes baking time is not even close to enough time. I baked it for 32 minutes and even then it was doughy in the center. I wasn’t pleased with it when I served it yesterday. I loved the taste but the inside as doughy. Today I love it! The inside has set up and it is the perfect texture. I would make this again for sure. It is a fun treat to give. I would definitely make it the day before and bake it for 32-35 minutes. Also, I wanted to say that I LOVE this site. I have had success with everything I have made from it.
Hi Cindy, thanks so much for leaving your feedback! Hopefully this is helpful to others who don’t enjoy a more gooey texture (which I personally do). I’m so happy to hear you love the site!! 🙂
Glad I read the other reader comments. True bake time for me was more like 35 minutes and the center was still gooey and soft (in a good way). This dessert is super rich, a very small serving satisfies. So swee doesn’t need the buttercream frosting, although it’s a great frosting recipe. Definitely a big hit in my house!
Can this dough be made ahead of time? I would like to make it a few days in advance and pop it in the freezer. Will it still bake correctly? Also, how long would the frosting keep in the fridge? I’m excited to try this recipe!

Can i use light brown sugar instead of dark brown? Thats all I have.
Also if you could check your email from me, that would be great!
Great recipe, but be careful, the grams don’t match the cup measurements!
This cookie cake recipe is amazing! Made it for my sisters birthday and everyone could not get enough. They raved about it being perfectly gooey in the middle. I will definitely be making this again!
