Name: Chocolate 'Mallow Cookie Cups
Total time: 1 h 55 min
Ingredients: 1 1/2 cups (7 1/2 ounces/213 grams) all-purpose flour; 1/2 cup (1 1/2 ounces/43 grams) unsweetened cocoa powder; 1/4 teaspoon salt; 1/4 teaspoon baking soda; 1/4 teaspoon baking powder; 1 cup (7 ounces/198 grams) sugar; 8 tablespoons unsalted butter , softened; 1 large egg; 1 teaspoon vanilla extract; 40 mini-marshmallows; 1/4 cup milk chocolate chips

Why This Recipe Works

This cookie cup is made by stuffing chocolate cookie dough with marshmallows. By making the dough more firm than our usual cookie dough, it is easier to roll out and wrap around the marshmallows. Baking them in mini muffin cups and decorating them with melted chocolate makes these cookie cups impressive enough for any cookie swap. UPDATE: This recipe has been slightly reformulated to be more foolproof since its initial publication. The revision you see here was published in September of 2019.

Before You Begin

If you do not have a mini muffin tin, use mini foil cups placed on a baking sheet.

Instructions

Adjust oven rack to middle position and heat oven to 350 degrees. Line mini muffin tin with 20 paper or foil liners. Whisk flour, cocoa, salt, baking soda, and baking powder together in bowl; set aside.

Using stand mixer fitted with paddle, beat sugar and butter on medium-high speed until pale and fluffy, about 3 minutes. Add egg and vanilla and beat until combined. Reduce speed to low and add flour mixture in 2 additions until well combined, scraping down bowl as needed.

Divide dough into 20 heaping tablespoons and roll into balls. On lightly floured counter, press each ball into 3-inch circle. Place 2 mini-marshmallows in center of each circle and wrap dough around mixture, pinching to seal. Roll into smooth ball and pinch to seal any cracks where marshmallows are exposed. Place in liners in muffin tin.

Bake until just set, 10 to 12 minutes, rotating muffin tin halfway through baking. Let cookies cool in muffin tin for 15 minutes, then transfer to wire rack and let cool completely.

Microwave chocolate chips in bowl at 50 percent power, stirring occasionally, until melted, about 1 minute. Spread chocolate over cookies and let set for at least 20 minutes before serving.
