Fake out your friends with Cupfakes - sculpted plaster cupcakes that look deliciously similar to the real thing. We'll use plaster to cast the cakes. Then we'll frost the Cupfakes with a pastry bag and real piping tips, just like a bakery - except our icing will be tinted spackling paste. Various icing techniques will be taught. Sprinkles will definitely be involved. Teens will learn professional cake decorating techniques that can apply to genuine cupcakes in the future.
