Remember Mallomars? These cookies remind me a little of them, except instead of a graham cracker base, they have a chocolate cookie base which is crunchy on the outside and chewy on the inside. The marshmallow in the middle is a nice gooey surprise, and the chocolate frosting adds to their richness.
Just some notes: The dough is very thick and fudge-like. I used non-fat milk because that’s what I had in the house and it worked just fine. I originally used a 1 3/4″ cookie scoop but decided on a smaller scoop midway through because my cookies didn’t spread much, they just puffed up. Also, I had a ton of frosting leftover!

Cookie Ingredients
1 3/4 cups all-purpose flour
3/4 cup unsweetened cocoa powder (not Dutch-process)
1/2 teaspoon baking soda
1/2 teaspoon coarse salt
1/2 cup (1 stick) unsalted butter, room temperature
1 cup granulated sugar
1 large egg
1/2 cup whole milk
1 teaspoon pure vanilla extract
About 15 large marshmallows, halved crosswise (cut in half horizontally)
Frosting Ingredients
3 cups confectioners’ sugar
6 tablespoons unsalted butter, room temperature
1/4 cup plus 1 1/2 teaspoons unsweetened cocoa powder (not Dutch-process)
1/4 cup plus 2 tablespoons whole milk
3/4 teaspoon pure vanilla extract
Preparation
- Preheat oven to 375 degrees. Make cookies: Sift together flour, cocoa powder, baking soda, and salt into a bowl.
- In the bowl of an electric mixer fitted with the paddle attachment, cream together butter and sugar until light and fluffy, about 2 minutes. Add egg, milk, and vanilla, and beat until well combined. Add reserved flour mixture; mix on low speed until combined.
- Using a tablespoon or 1 3/4-inch ice cream scoop, drop dough onto baking sheets lined with parchment paper, about 2 inches apart. Bake until cookies begin to spread and become firm, 8 to 10 minutes.
- Remove baking sheets from oven, and place a marshmallow, cut-side down, in the center of each cookie, pressing down slightly. Return to oven, and continue baking until marshmallows begins to melt, 2 to 2 1/2 minutes. Transfer cookies to a wire rack to cool completely before frosting.
- Make frosting: Put confectioners’ sugar in a medium bowl. Melt butter with the cocoa powder in a saucepan over medium-low heat, stirring occasionally. Add butter mixture to the confectioners’ sugar. Whisk in the milk and vanilla.
- Spread about 1 tablespoon of frosting over each marshmallow, starting in the center and continuing outward until marshmallow is covered. Let stand until set, about 10 minutes, Cookies can be stored in single layers in airtight containers at room temperature up to 2 days.
