I didn't have the board to go in the box, and was too lazy to go buy one so I cut cardboard with a craft knife and covered it with wax paper. Put a bit of frosting on the board so the cakes will stick. I made this recipe for buttercream from Confessions of a Cookbook Queen.
I freehanded a bunny face with melted candy melts on wax paper. I am LESS than thrilled with how it turned out, but it was for family, and it was FREE!
