Share a little about the materials, processes, and techniques used to create this cake Decadent Chocolate cake recipie, vanilla buttercream, vanilla fondant, rice krispies, gel colours, non-toxic coloured pens, cake board, sparklers. What are you most proud of? The way it all came together. I'm getting much better working with fondant. What advice would you give someone starting this project? Make Stewie out of the rice krispies prior to decorating the cake as it will take overnight for the fondant covering it to set so that you won't leave fingerprints in it when you handle it. The ears, head, eyes etc. were attached using only water. When dried, the pieces will stick together like glue was used. I applied 2 layers of fondant. The first layer was pushed into the holes left when the rice krispies were cooked and formed so that the second layer would go on smoothly.
