This is the cake I made for my daughters graduation from preschool. I used 2 10-inch rounds stacked on bottom and 2 6-inch rounds stacked on top. The cake is iced in buttercream with the letters, numbers and shapes cut from fondant. The graduation cap I purchased the morning of the graduation, because I didn't know they were actually wearing graduation caps and receiving diplomas at the ceremony until they had their practice that morning. My original intention was to have the stars standing up on the top, but they didn't dry completely so I bought the cap instead and made due. They stars on top have the 5 childrens names on them that were graduating from the class. The cake was a hit with the kids!!
