This is a buttercream transfer cake. The kids were very impressed with it. It is easiest to do with a cartoon image; Sponge Bob qualifies. The nice thing about buttercream transfer cakes is that you can copy just about any simplistic commercial image and it looks perfect. The image is made of buttercream, not plastic, or fondant, or anything like that. You can eat the icing but the main ingredient is Crisco and I don't eat it.
