Preheat the oven to 400°F. Spray a muffin pan with nonstick cooking spray.
Roll out the pizza dough into a large rectangle and cut into 12 squares.
Top each dough square with pizza sauce, three pepperoni slices, and a cube of mozzarella cheese.
Fold the dough's edges over the filling and pinch to seal, creating a compact bundle.
Place the dough bundles seam-side down in the prepared muffin pan.
Bake for 15 to 18 minutes, until golden brown.
In a small bowl, whisk together the melted butter and Italian seasoning.
Brush the hot rolls with the garlic butter mixture and sprinkle with grated Parmesan cheese.
Serve warm with additional pizza sauce for dipping.
