01 - Preheat the oven to 400°F. Line a baking sheet with parchment paper.
02 - Lightly dust a clean work surface with flour. Roll the pizza dough into a rectangle roughly 10x14 inches.
03 - Distribute mozzarella and Parmesan cheeses evenly over the dough, leaving a 1/2-inch border around the edges. Arrange pepperoni slices in an even layer on top of the cheese.
04 - Starting from one long edge, roll the dough up tightly into a log. Pinch the seam firmly 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, leaving space between them for even baking.
07 - Combine the melted butter, garlic powder, and Italian seasoning in a small bowl. Brush the mixture generously over the tops and sides of each roll.
08 - Bake for 16 to 20 minutes until the tops are golden brown and the cheese is bubbling.
09 - Remove from the oven and sprinkle with fresh parsley. Serve warm with marinara sauce for dipping.
