This is a yellow pudding cake with a buttercream frosting. The water is blue gel icing. The sand is grahm cracker crumbs. The palm trees are royal icing. The hut is made from a plastic cup (for shape), pretzels, and royal icing to hold it together. I made this cake for a second grade teacher at the school I work in. His class did a couple lessons on expository writing on how to make and decorate a cake! This was such a fun cake to make!
