Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
On a lightly floured surface, roll out the refrigerated pizza dough into a rectangular shape, about 1/4 inch thick.
Sprinkle the shredded mozzarella cheese evenly over the dough, leaving a small border around the edges.
Layer the pepperoni on top of the cheese, spreading it out evenly.
In a small bowl, mix the garlic powder, Italian seasoning, and crushed red pepper flakes (if using). Sprinkle this mixture over the pepperoni layer for added flavor.
Carefully roll the dough up tightly from the bottom to the top, ensuring the filling stays inside. Pinch the ends to seal.
Cut the roll into 1-inch slices and place them cut-side up on the prepared baking sheet. Brush the tops with olive oil for a golden finish.
Bake in the preheated oven for 15-18 minutes, or until golden brown and bubbly.
Remove from the oven and let cool for a few minutes. Serve with the pizza sauce for dipping and garnish with fresh basil leaves if desired.
