01 - In a mixing bowl, combine granulated sugar and active dry yeast with warm water. Let stand for 5 minutes until foamy.
02 - Add all-purpose flour, olive oil, and salt to the yeast mixture. Mix and knead for 5 to 7 minutes until the dough becomes smooth and elastic. Cover and allow to rise in a warm environment for 1 hour, or until dough doubles in size.
03 - Preheat oven to 400°F (200°C). Line a baking sheet with parchment paper.
04 - On a lightly floured surface, roll the dough into a 10 by 14 inch rectangle.
05 - Distribute shredded mozzarella, sliced pepperoni, dried oregano, and garlic powder evenly across the dough.
06 - Roll up the dough tightly starting from the long edge. Slice into 12 equal pieces.
07 - Transfer slices seam-side down onto the prepared baking sheet. Brush each roll with melted butter and sprinkle with grated Parmesan cheese.
08 - Bake for 18 to 20 minutes or until rolls are golden brown and cooked through.
09 - Serve warm, accompanied by marinara sauce for dipping if desired.
