I will be placing a 9x13 sheet cake on top of a 12x18 sheet cake, and I was wondering, has anyone tried using wax or parchment paper under the cake board that is on the top, to help keep the icing from sticking to the bottom of the cake board?
I havent heard of that, but if you are going to try that I would put powdered sugar under the wax paper, on the icing, so the wax paper doesnt stick to the icing. Just-in-case! Some poeple just put powdered sugar, or coconut flakes. Good Luck!
