Share a little about the materials, processes, and techniques used to create this cake Cake, fondant, buttercream, gel color, Rice Krispie cereal. What are you most proud of? I didn't follow a pattern or instructions! I also built it like a hamburger so when you cut it, it had a hamburger profile. What advice would you give someone starting this project? Just think of what you like on your hamburger and play with your colours. For the fries, I like mine crispy, so I even toasted my pound cake fries lightly in my toaster oven. Use your imagination and have fun. Mistakes can be eaten!
