The infamous pizza cake came to life in April of 2014 when a Canadian-based chain Boston Pizza started a campaign called Pizza Game Changers, where the public was called in to vote on the next big thing when it comes to pizza-related products.

Pizza cake won the race by miles and since its appearance had people either salivating or shaking their heads in denial. The cake in question is actually made up of multiple layers of pizza that are baked in a pot or a cake pan with tall sides. The recipes vary in the number of pizza layers, ranging from three to six, but the stuffing is always the same; tomato sauce, pepperoni, and heaps of cheese.
