A pizza cake is a multiple-layer pizza baked in a pot or cake pan. In April 2014, Canadian-based chain Boston Pizza included the pizza cake as part of its Pizza Game Changers promotion. The campaign called on Canucks to vote for the most outrageous pizza innovation, with the pizza cake described as "Great for birthdays, bar mitzvahs, weddings, and even lonely nights watching infomercials." It easily topped the second place creation, the pizza mint.
Recipes soon started circulating online, including ones posted by the So Good Blog and the Pillsbury Company.
