There are more than just round, square, and sheet cakes. There are heart, hexagon,and oval shaped cakes. Along with those types of cakes, there are also specialized carved cakes. For example, I carve and use numerous shaped pans to design number cakes! There is really not a form that I can show you for those. But that is why custom cakes are so magnificent and special!! You can have a cake that is detailed just the way you'd like it.
