Divide the pizza dough into 4 equal parts and roll each piece into a 6-inch circular shape.

Spread pizza sauce on one side of each circle, leaving half an inch around the edges.

Sprinkle mozzarella cheese and layers of pepperoni on top of the sauce.

Fold the dough over and crimp edges securely to seal.

Preheat air fryer to 375°F and lightly spray the basket with oil.

Place calzones in a single layer and air fry for 7-10 minutes, flipping halfway.

Remove calzones, let cool for a minute, then brush with garlic butter and sprinkle with cheese or seasoning.

Serve warm with marinara sauce for dipping.
