PREPARE cookies as directed on package. Cool completely.
COLOR white frosting as desired (one color can be used or divide frosting and have several colors. One container of frosting will be enough to make all 12).
SPOON 1 heaping tablespoon of frosting in center of 12 cookies. Top each with remaining 12 cookies. To make monster hair on top of cookie, fill pastry bag or small plastic food storage bag fitted with star tip with frosting. Squeeze bag lightly to pipe hair. Position eyes onto front of hair. Use frosting to adhere mini morsels to eyes for pupils. Insert almonds in filling for teeth. Decorate monsters as desired with additional sprinkles or licorice for an extra scary monster!
