Ingredients
For the cookies:
- 1 3/4 cups all-purpose flour
- 3/4 cup unsweetened cocoa powder
- 1/2 teaspoon baking soda
- 1/2 teaspoon salt
- 1 stick (8 tablespoons) unsalted butter, at room temperature
- 1 cup granulated sugar
- 1 large egg
- 2 cup whole milk
- 1 teaspoon vanilla extract
- About 15 marshmallows, halved crosswise
For the frosting:
- 3 cups confectioners' sugar
- 6 tablespoons unsalted butter
- 1/4 cup unsweetened cocoa powder
- 1/4 cup plus 2 tablespoons whole milk
- 4 teaspoon vanilla extract
Directions
For the cookies:
-
Preheat oven to 375°F. Line large baking sheets with parchment paper or silicone baking mats.
-
In a medium bowl, sift together flour, cocoa, baking soda, and salt.
-
In the bowl of an electric mixer beat the butter and sugar on medium-high speed until light in color and fluffy, 2 to 3 minutes. Reduce speed to medium-low and mix in the egg, milk, and vanilla. On low speed gradually mix in the flour mixture until combined.
-
Using a 1 1/2-tablespoon ice cream scoop, drop dough onto prepared baking sheets spacing 2 inches apart. Bake cookies until firm, 8 to 10 minutes. Immediately press a marshmallow half on top of each cookie. Bake until marshmallow begins to melt, 2 minutes more. Let cookies cool completely on baking sheets on wire racks.
For the frosting:
-
Place confectioners' sugar in a medium bowl. Melt butter with cocoa powder in a small saucepan over medium-low heat, stirring occasionally. Add butter mixture to confectioners' sugar. Whisk in milk and vanilla until thick and smooth.
To assemble:
-
Spread about 1 tablespoon of frosting on top of each cooled cookie to cover marshmallow. Let stand at room temperature until set, about 10 minutes. Cookies can be stores in single layers in airtight containers for up to 2 days.
Recipe Notes
From Cookies by Martha Stewart
These look amazing! I just made my MIL a chocolate cake with marshmallow frosting last week – it's true – the combo is to die for!
These look delicious, always happy to find that kind of surprise in my cookies:-)
I love the marshmallow surprise idea. You could even sprinkle graham cracker crumbs on top and make it s'more cookie.
Yum, chocolate and marshmallows – good combo! I must have missed this recipe in my MS Cookies book, but I'm looking forward to trying it now 🙂
I love the surprise center! What a great idea and if this was for a gender reveal party, you could probably dye the insides for the gender of the baby! This looks delicious
What a cute idea!!
What a great idea. I'm a sucker for fillings and surprises. I'm gonna have to make these asap
I made this same recipe during Christmas with a bit of peppermint extract in the batter and with big, flat round peppermint marshmallows that Jet Puffed came out with. They were a huge hit… I made them for a class and my little professor literally body-checked a 30 yr old grad student to keep him from taking “her cookies.” She was only kind of joking 🙂
These look absolutely sinful in the best way possible! Love the surprise center 🙂
Oh my lands, the Mr would love these! I'm bookmarking–thanks! 🙂
We used to make a brownie really similar to this. I agree, anytime chocolate and marshmallow get together, it's bound to be good!
this reminds me of a mallomar…which always come out around this time! yum! kind of perfect for spring/easter time…you could do them with peeps 🙂
These are some of my favorite cookies! I always make them around the holidays and they are huge hit! Yours look great!
These cookies look delicious! So many variation possibilities! Yum!
