I have seen this done so many times on tv cake shows, so I was very intrigued when I was asked to make one. I used buttercream icing as the marinara sauce, melted white chocolate for the melted cheese, and grated fondant for the shredded cheese. The pepperoni, black olives and sausages are all fondant. The checkered board and napkin note are also fondant....couldn't figure out exactly how to get "Happy Birthday Cason" on there. The pictures don't really show it, but the "napkin" is textured to look like a real napkin.
Well, Tuesday is our pizza night, so I am off to eat the real thing! Maybe I will show them a picture of my pizza and see if they catch on that it is a cake.
