Preheat your air fryer to 350°F (175°C).
Flatten each biscuit and add 1 teaspoon of pizza sauce, mozzarella cheese, and a few pepperoni slices.
Fold the biscuit dough over the filling and pinch the edges to seal.
Place the pizza bombs in the air fryer basket, seam-side down.
Brush with melted butter and sprinkle with garlic powder, Italian seasoning, and Parmesan cheese.
Air fry for 6-8 minutes until golden brown and crispy.
Serve warm with extra pizza sauce for dipping.
