Chocolate Cookies with Marshmallow Filling

Chocolate Cookies with Marshmallow Filling

Cookies

1 1/4 cups all-purpose flour
1/2 cup unsweetened Dutch process cocoa
1 teaspoon baking soda
1/4 teaspoon baking powder
1/4 teaspoon salt
1 to 1 1/2 cups sugar [see recipe note]
1/2 cup plus 2 tablespoons (1 1/4 sticks) room-temperature, unsalted butter
1 large egg

Set two racks in the middle of the oven. Preheat to 375°F.  

In a food processor, or bowl of an electric mixer, thoroughly mix the flour, cocoa, baking soda and powder, salt, and sugar. While pulsing, or on low speed, add the butter, and then the egg. Continue processing or mixing until dough comes together in a mass.

Take rounded teaspoons of batter and place on a parchment paper-lined baking sheet approximately two inches apart. With moistened hands, slightly flatten the dough. Bake for 9 minutes, rotating once for even baking. Set baking sheets on a rack to cool.

Marshmallow Filling - Annie's Eats

 1 cup (2 sticks) unsalted butter, at room temperature
2 cups confectioners’ sugar, sifted
7½ oz. marshmallow fluff
2 tsp. vanilla extract

To make the filling, place the butter in the bowl of a mixer fitted with the paddle attachment.  Beat on medium-high speed until smooth, 1-2 minutes.  Blend in the confectioners’ sugar until incorporated.  Beat in the marshmallow fluff and vanilla until light and fluffy, 2-3 minutes.

After cookies have cooled, spread a tablespoon of filling between two cookies. Repeat with remaining cookies.
