1. Roll yellow gumdrops out onto sugared surface. Cut out 3/4-inch stars. Tint frosting green; spoon into a pastry bag fitted with a 1/4-inch star tip. Pipe frosting so that it hangs over larger cupcakes. Continue piping, to cover. Place green gumdrops in centers of mini cupcakes; pipe as before. Stack mini cupcakes on top of larger cupcakes, and decorate with nonpareils. Top with yellow stars.
