I posted this cake once before, but I wanted to add some information, I had to delete it and post again. Apologies to those who had saved this cake photo. I am very grateful for all the amazing castle cakes and inspirational ideas on this site! My first castle cake is made with 6" and 8" tiers of chocolate cake covered with vanilla buttercream. Towers are made of molasses and Oreo cookies covered with fondant and fondant steps and stonework. Roofs, windows, door, and castellations are made of chocolate plastique.
