I took a cake professional decorating class decades ago. We decorated lots of styrofoam cakes. LOL I remember for my final test and certificate we had to present a decorated cake for a holiday. I choose Halloween. I baked two bunt cakes, Turned one upside down and put the other on top. I cut windows and doors. I made a pumpkin house with lots details. I won a complete set of cake decorating tools. Back then the tools were hard to find in stores. I still use the cake pan belt strips. The strips are made from the silver heat resistant fabric that are padded. They have been washed so many times and still together. The belts will keep the cake baking evenly. A leveler is used for the cake to keep it flat so the layers will not topple. I haven't decorated a cake in years but still use these two baking tools.
