Preheat oven to 375℉. Grease 8 regular-sized muffin cups.
Open the crescent roll dough and separate into triangles. Place a triangle of dough into each prepared muffin cup, pressing it to fit.
Spoon 1 tablespoon of sauce into each dough-lined cup. Divide cheese over each cup, followed by your pizza toppings of choice. Top with a sprinkle of Parmesan cheese.
Bake for 14 to 16 minutes, or until edges are golden. Serve warm.
Notes
Lightly tent with foil while baking if the tops of the pizza cupcakes start to get too brown.
