This was a very fun cake to customize for the college graduate! I started with two 9x13's stacked on top of one another (with a vanilla pudding in the middle) and frosted it to look like a super big textbook. Then I carved a 6" cake to look like the shape of a graduation hat and placed dried gum paste on top to act as the mortarboard. I also shaped some gum paste into a diploma and let that dry so I could add another prop to the cake. I think it turned out spectacular!
