Preheat oven to 450 degrees. Dice pizza fillings into very small pieces. Spray cupcake tin with cooking spray.
Roll out pizza dough. Using a 3-inch cookie cutter, cut 6 rounds, then repeat with the 2-inch cutter.
Place 3-inch rounds in the cupcake tins. Spoon sauce all around the inside, then layer toppings like a parfait.
Top each pie with a 2-inch round, pressing edges together. Cut a small vent in the center of each pie. Bake about 15 minutes, brushing tops with olive oil halfway through. Pies are done when they’re golden and filling is bubbling!
