Share a little about the materials, processes, and techniques used to create this cake Two carved red velvet cakes covered in fondant. Blood made out of a combination of piping gel & corn syrup. What are you most proud of? I love how the brain turned out, but even though it was easier, I am in love with the heart! :) What advice would you give someone starting this project? Carve the cakes a little at a time. You can always take more off, but once you cut off the cake, you can't put it back!
