This is a graduation cake I made for a co-worker. The colors of the cap and gown were going to be white, so he wanted mostly white, but the school colors also included silver and blue.
I actually made two 8″ inch double-layer cakes (one chocolate, one yellow), and put them side by side and then covered with fondant. He wanted some of each flavor and I thought that was an easy way to do it.
The graduation cap is yellow cake as well.
