01 - Preheat oven to 400°F. Line a baking sheet with parchment paper.
02 - Lightly dust a work surface with flour. Roll the pizza dough into a 10x14-inch rectangle.
03 - Sprinkle mozzarella and Parmesan cheeses evenly over the dough, leaving a 1/2-inch border. Layer pepperoni slices on top of the cheese.
04 - Starting from the long edge, roll the dough up tightly into a log. Pinch the seam to seal.
05 - Using a sharp knife, cut the log into 8 equal pieces.
06 - Place each piece cut side up on the prepared baking sheet, spacing them apart.
07 - In a small bowl, mix melted butter, garlic powder, and Italian seasoning. Brush generously over the tops and sides of the rolls.
08 - Bake for 16 to 20 minutes until golden brown and cheese is bubbling.
09 - Remove from oven and sprinkle with parsley. Serve warm with marinara sauce for dipping.
