I made this cake for my mom's birthday. She loves to eat sushi with her friends and I thought this would be the perfect cake. The base is an 8 inch square chocolate cake iced in chocolate buttercream icing and then covered in chocolate MMF. The california rolls are Cakesters that I cut into circles and covered in fondant. The rice, crab and avocado are all gumpaste. Everything else on the cake is made of fondant and the fondant soy sauce dish is filled with brown colored corn syrup. Enjoy!
