Your little human monsters will love decorating brownies with chocolate, marshmallows, and M&M's to make these sweet treats. For the base, we doubled the recipe for Dark Chocolate Brownies, baking it in a 9- by 13-in. pan and omitting the glaze. Thin, flat chocolate bars work best for the faces.

Ingredient Checklist


Instructions Checklist
  • Preheat broiler with rack 4 in. from heat. Trim edges from brownies and save for snacks. Cut remaining brownies into 12 squares, each about 2 1/2 in., and set on a parchment paper-lined baking sheet. Place a piece of chocolate on each brownie with scored side down.

  • Arrange a variety of mini and regular marshmallows on each brownie to make faces: To make eyes, cut mini or regular marshmallows in half crosswise and press into chocolate, then place regular or mini M&M's into center of marshmallows. To make teeth, cut marshmallows into triangles and press into chocolate.

  • Place brownies under broiler and broil, watching carefully, until marshmallows are just browned and chocolate is a little melted, about 30 seconds, rotating pan if needed for even browning. Let cool a few minutes before serving.
