Surprise your little goblins with monster-headed cupcakes filled with a slimy surprise-green pudding.
Bake and cool 2 dozen cupcakes from your favorite recipe. Prepare a 3.4-ounce box of vanilla-flavored instant pudding. Stir in drops of green food coloring until you have a shade you like, then place it in the refrigerator to chill.
Next, microwave 1 cup of green melting candy (we used Wilton Candy Melts, available at party supply stores) for 1 minute at 50 percent power, then stir. If necessary, heat in 15-second intervals until completely melted. One at a time, spear 24 large marshmallows with a skewer and roll them in the melted candy, coating the sides. Set them on a waxed-paper-lined baking sheet, add M&M's Minis for eyes, and place them in the refrigerator to chill.
With a small serrated knife, remove a 1-inch-wide chunk from the center of each cupcake. Fill each hole with a tablespoon or so of the pudding, then spread chocolate frosting around each pudding hole.
Cover each pool of pudding with a chilled marshmallow. Add black gel facial features and 2 green Tic Tac mints for bolts.
Finally, top each monster head with a bit of frosting and muss with your finger or a fork. Keep the cupcakes chilled until serving time.
