Our basis for these was a plain pizza crust which we baked at 375 for 20 minutes.This was a family favorite. Spread peanut butter on the bottom , top with marshmallows (we realized the more marshmallows the better, especially if you broil them for a few moments) after you bake top with chocolate sauce.
Spread melted butter and sprinkle with cinnamon and sugar for an easy one.Spread on strawberry jam, bake for 10 minutes and when out sprinkle with powdered sugar.
On a cooked crust, add apple pie filling. We used frozen chopped up apples from the previous fall (we were going to use in apple pie) It already had some sugar so no need to add any. After we heated it in the oven, we sprinkled with powdered sugar.
These were all very yummy ways to make dessert pizza.
