Asked to make this for my church service. 1/2 sheet with half chocolate cake, half confetti. Buttercream frosting w/buttercream border & writing. Silver luster dust sprinkled on black shell border. Rainbow sprinkles on sides & numbers. Got the number idea from mbpbrighteyes; they are fondant painted in luster dust... made the mistake of making them last night, so they didn't have much time to dry. Live & learn!
