I had a someone ask me to make a 6 layer 9 inch rainbow cake allergy free. I had never seen one before but was up for the challenge. The Allergy Free Vanilla Cake recipe stood up to 6 layers piled high. Its such a beautiful cake to cut into. My kids enjoyed watching the batter change color. Two main tips: make sure to line each pan with parchment paper. Since each layer is thinner than a regular cake layer they are a bit more delicate. Make sure to use gel food coloring. It makes very bright colors.
