Prepare the cupcakes according to your box mix. Let them cool completely before icing. Beat together on high the can of icing, crisco or butter, vanilla and confectioners sugar.

Cut each cupcake in half and turn the round edges facing each other. Attach them together with the icing then use the icing to cover them. Use the M&M's, sprinkles and any other toppings to decorate. I also used toothpicks to make the antennas.
