Ingredients

  • 2 1/4 cups all-purpose flour 280g
  • 1/2 cup Dutch-process cocoa powder 58g
  • 2 tsp baking soda
  • 1/2 tsp kosher salt
  • 1/4 tsp ground nutmeg
  • 3/4 cup unsalted butter, at room temperature
  • 3/4 cup granulated sugar, divided
  • 3/4 cup light brown sugar
  • 1 large egg at room temperature
  • 1 egg yolk at room temperature
  • 1 tsp vanilla extract
  • 1 1/2 cups mini marshmallows, frozen

Instructions

  • Combine flour, cocoa powder, baking soda, salt, and nutmeg in a large bowl.
  • Beat butter, 1/2 cup granulated sugar, and brown sugar on medium speed in the bowl of a stand mixer fitted with the paddle attachment 2 to 3 minutes or until light and fluffy.
  • Beat in egg and egg yolk, beating well after each addition. Beat in vanilla. Cover the bowl with plastic wrap and chill at least 30 minutes or overnight.
  • Preheat oven to 325°F. Line 2 baking sheets with parchment paper. Add 1/4 cup granulated sugar to a shallow bowl.
  • Portion out 1 oz of dough and press it into a disc. Press 4 to 5 frozen marshmallows into the dough and cover with another 1 oz of dough, creasing the sides to enclose the marshmallows. Roll into a ball, roll in granulated sugar, and place about 2 inches apart on prepared baking sheets.
  • Repeat with remaining dough and marshmallows.
  • Use the bottom of a small glass to lightly press each cookie dough ball down (just a little bit, they need some help spreading!).
  • Bake 10 to 13 minutes or until the centers of the cookies are set. Cool completely or enjoy while warm.
