Share a little about the materials, processes, and techniques used to create this cake Cake, Buttercream, Fondant, Rice Krispy Treats, Chocolate. What are you most proud of? It looked so real the 2 year olds were trying to get it to move by throwing Graham Cracker Crumbs at it. What advice would you give someone starting this project? Pe ver patient and take your time...This cake took me 2 weeks to put together. I did a lot of research. The fish and the Turtle head are Rice Krispy Treats, covered over w/chocolate and then fondant. The turtle back is fondant and then airbrushed.
