This was a fun cake to make. It is a single 12" layer iced with buttercream. The edge was built up with icing and airbrushed to looked baked. The tomato sauce is thinned colored buttercream and piping gel with chocolate cake crumbs added to look like spices. I made the pepperoni by adding alot of powdered sugar to colored buttercream to make a dough and rolled it into a log and then sliced it. The chesse was made the same way. I did not use any fondant. I purchased the pizza box from a retailer. This party was held at a pizza palor!
