Chocolate Surprise Cookies

Print This Recipe Print This Recipe
Remember Mallomars? These cookies remind me a little of them, Chocolate Surprise Cookiesexcept 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!

Photos of the process here.

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


  1. Preheat oven to 375 degrees. Make cookies: Sift together flour, cocoa powder, baking soda, and salt into a bowl.
  2. 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.
  3. 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.
  4. 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.
  5. 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.
  6. 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.

    I never heard of Mallomars but these so remind me of the old wagon wheels – just puffier. I could probably dispense with about 6 of those babies.

    Your pic looks so much better than mine. They were substantial, using the bigger scoop. My son ate his with a fork. He was asking for these cookies well after they were all gone.

    It’s funny because I never liked the prepackaged mallomars, but then not so long ago someone had home-made ones and I became an instant, later-on-in-life devotee. These look like a fantastic specimen. And as for extra frosting…that doesn’t sound like a bad thing to me (*spoon at the ready*)

    I made these recently (well, I made the dough, then my daughter baked them and frosted them and took all the credit!) and they are good. You do have to have a sweet a tooth to like these, but they are really good.

    These are what we call Teacakes in the UK – you can buy Tunnock’s Teacakes individually wrapped in seductive stripey foil!
