I made this cake for my son's 5th birthday. It was really fun! White choc. cakes with strawberry filling. They are a half sheet, 10 in square, and 8 in round carved to look like a desert mountainside and covered in crushed nilla wafers and graham crackers. The cactus and signs are made of royal icing and the signs are handpainted with food color. The rocks and road are fondant and the rock formations were rice krispie treats covered in fondant and sponge painted.
