This is a pepperoni pizza cake, which is just a layer of pizza, topped with another layer, and another, and...sorry, drooling.
Now Pillsbury has published a super-easy recipe for pepperoni pizza cake that will take you about an hour to make.
Instead of a homemade pizza crust, you can use two cans of Pillsbury refrigerated crust to save time.
Roll out the dough, and cut out five circles wide enough to fit the tall cake pan you plan to use. (Two circles will be the bottom and top layers, and the remaining three will go in the middle of your pizza cake.)
