Prepare the Dough: Unroll the refrigerated pizza dough onto a cutting board or flat surface, shaping it into a rectangle. Using a sharp knife or pizza cutter, slice the dough into nine equal rectangles.

Assemble the Rolls: Place 4 slices of pepperoni in the center of each rectangle. Add about 1 tablespoon of shredded mozzarella cheese on top of the pepperoni. Fold the dough over the pepperoni and cheese, pressing the edges to seal the seam. Fold up the ends and press them into place to ensure the filling is enclosed. Place each assembled roll seam-side down.

Season the Rolls: Melt the butter in a small microwave-safe bowl. In a separate bowl, mix the garlic powder, salt, and Italian seasoning. Using a pastry brush, coat each pepperoni roll with melted butter, then sprinkle the garlic seasoning mixture on top.

Air Fry the Rolls: Arrange the pepperoni rolls in the air fryer basket, leaving space between each one. Cook at 350°F for 8-10 minutes or until the rolls are golden brown and cooked through.

Serve and Enjoy: Serve the crispy, cheesy air fryer pepperoni rolls immediately and enjoy!
