Your guests will have as much fun making these cute cupcakes as they will eating them! Bake 2 dozen chocolate cupcakes according to the package directions on a Pillsbury® Moist Supreme® Cake Mix, or follow your own recipe. When they are cool, remove liners. Frost the top of 12 cupcakes with your child's favorite Pillsbury® Creamy Supreme® Frosting. On the top of each frosted cupcake, place an unfrosted cupcake upside-down, securing it with a toothpick. Frost the upside-down cupcakes on all sides. Break several Oreo® cookies in half and place two halves on top of each cupcake for ears. Use chocolate chips, M&M's®, or other small candies of your choice to make eyes, a nose and a mouth.
