Surprise Cookies


These delicious treats were inspired by mugs of hot chocolate topped with marshmallows.

  • Yield: Makes about 2 dozen

Source: Martha Stewart Kids, Winter 2004


  • 1 3/4 cups all-purpose flour
  • 3/4 cup cocoa powder
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1/2 cup (1 stick) unsalted butter, softened
  • 1 cup sugar
  • 1 large egg
  • 1/2 cup milk
  • 1 teaspoon pure vanilla extract
  • 12 large marshmallows, cut in half horizontally
  • Chocolate Frosting for Surprise Cookies


  1. Preheat oven to 375 degrees. In a medium bowl, whisk together flour, cocoa powder, baking soda, and salt; set aside.

  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 ungreased baking sheets, about 2 inches apart. Bake until cookies begin to spread and become firm, 10 to 12 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 begin to melt, 2 to 2 1/2 minutes. Transfer cookies to a wire rack to cool completely before frosting.

  5. Spread about 1 tablespoon of frosting over each marshmallow, starting in the center and continuing outward until marshmallow is covered.

Cook's Notes

If you're putting two sheets in the oven at a time, switch top and bottom sheets halfway through for more even baking. To stack cookies, wait until frosting dries, then place waxed paper in between the layers to keep the frosting from smearing.

    These are my favorite cookies! And everyone who tasted them loved them too. I added a few chocolate chips in the cookies and have a soft and crunchy feel at the same time! It is the best recipie for the ones who love chocolate.

    Yummy & rich! Tips based on my experience - 12 fit on a full size sheet pan, they don't melt down flat so don't worry about them sticking together. I baked for 9 minutes, put the marshmallow on each (press it in a little), then another 2-and-a-half minutes for the marshmallow to soften. To flatten it more, I pushed down on it a bit with my fingers, a spoon would work too! I used my hand mixer for the frosting, still has little tiny lumps so I topped with chocolate sprinkles. Cake-like & yummy!

    After reading problem others had with dry cookies, I underbaked to 9 minutes, put the marshmallow on and baked only another minute. For the frosting, I sifted the sugar and cocoa, added the vanilla and melted butter and beat with hand mixer. I added milk gradually, beating well and it was smooth and glossy. I made them for a bake sale, but I had to sample one. It was very cake-like, almost like a mini cupcake. Will definitely make these again.

    Great cookies but I tweaked a bit. I added 1 tsp. of instant coffee to the batter. Just makes it more chocolatey (doesn't taste like coffee) and I didn't make the icing. I made chocolate ganache (semi sweet chocolate with a bit of cream) and poured it over the cookies on a rack. They were like homemade Mallomars. Very decadent and EASY! Will make tons for Christmas.

    I think these taste even better if you use salted butter, or add a pinch of salt!

    Do these need to be refrigerated? I figure yes, since there is milk in the frosting.
