Preheat oven to 375 degrees F (190 degrees C). Lightly spray a muffin pan with non stick spray.
Unroll the Crescent Roll Dough (1 package) triangles. Form the cresent dough triangles into a circular disc. Gently press the crescent dough into the bottom of each muffin tin.
Spoon 1 tablespoon of Pizza Sauce (8 tablespoon) into each dough filled cup. Layer each with even amounts of Cheese (1 cup) and Pepperoni Slice (1/2 cup).
Bake for 12 minutes until the dough is golden brown on the edges and the cheese is melted and bubbly.
Cool for 1 minute in the muffin pan. Gently move a knife around the edge of each pizza cup to release them from the pan. Serve warm.
