First things first, open up that can of biscuit dough. Separate each biscuit into its own little circle. Now, you need to flatten each biscuit out. You can use your hands or a small rolling pin. Aim for a circle about 4-5 inches across. Don't worry if they're not perfect circles, they're going to be little balls soon anyway!
Now, time for the good stuff! Spoon about 1 tablespoon of your pizza sauce right in the center of each flattened biscuit. Don't overfill, or they'll be harder to seal. Pile about 1/3 of your shredded mozzarella cheese on top of the sauce. Then, layer 3 slices of pepperoni over the cheese.
Here's the slightly tricky but fun part: becoming a bomb-builder! Carefully gather the edges of the dough up and around the filling. Bring all the sides together at the top and pinch them really, really well to seal it closed. You want to make sure there are no little holes or gaps where the cheese can escape while cooking. Roll it gently in your hands to make it a nice round ball. Repeat this for all eight biscuits.
While your bombs are ready, let's make that glorious topping. In a small bowl, whisk together the melted butter, garlic powder, Italian seasoning, and grated Parmesan cheese until it's all combined.
Now, brush each pizza bomb liberally with this amazing garlic butter mixture. Get all sides! This is what gives them that fantastic golden crust and extra flavor.
Preheat your air fryer to 350°F (175°C) if your model requires preheating. Carefully place your pizza bombs in the air fryer basket. This is important: make sure they are in a single layer and are not touching each other! Overcrowding will make them cook unevenly and they won't get that nice crispy exterior. You'll likely need to cook them in two batches.
Air fry for 7-10 minutes. Keep an eye on them! They're done when they are beautifully golden brown and look cooked through. The time can vary a bit depending on your air fryer, so start checking around 7 minutes.
Carefully remove the hot pizza bombs from the air fryer. If you're feeling fancy, sprinkle a little fresh chopped parsley over them right away.
Serve them immediately while they are hot and the cheese is super melty! Don't forget that extra pizza sauce on the side for dipping. Trust me, you'll want it!
