Prepare brownie mix according to box directions. Stir 2 cups chopped Milky Way into batter before spreading into a foil-lined jelly roll pan. Bake in a preheated 325°F oven for approximately 15 to 20 minutes. Cool completely. In the meantime, finely chop chocolate cookie crumbs with 12 caramel cookie bars in a food processor; set aside. Cover brownies with chocolate frosting and top with chocolate crumbs mixture. Refrigerate for 30 minutes. Cut brownies into 16 pieces. Transfer 1 cup of vanilla frosting into resealable plastic bag with a snipped corner. Pipe a skeleton on each brownie. Decorate with mini baking bits. Makes 16 brownies.

Tip: If short on time, consider using store-bought refrigerated sugar cookie dough. Begin by kneading 2/3 cup of flour into dough, then roll and cut according to the above directions. One roll of cookie dough makes approximately 18 cookies.
