Step 1: Preheat oven to 375°F (190°C). Line a baking sheet with parchment paper. (Preheating ensures even cooking. Parchment paper prevents the pizza bombs from sticking to the baking sheet and makes cleanup a breeze.)
Step 2: Separate each biscuit and flatten slightly using hands or rolling pin to form small circles. (Gently separate the biscuits and flatten them into roughly 3-4 inch circles. You can use your hands to press them down, or use a rolling pin for a more even thickness. The thinner the dough, the faster they will cook.)
Step 3: Place shredded mozzarella and mini pepperoni slices in center of each dough circle. (Don't overfill! About a tablespoon of mozzarella and a few mini pepperoni slices per circle should be perfect. Overfilling can make it difficult to seal the dough properly and may cause the filling to leak out during baking.)
Step 4: Fold dough edges up and around filling to form balls. Pinch edges to seal tightly. (Gather the edges of the dough and bring them together in the center, encasing the cheese and pepperoni. Pinch the seams tightly to ensure they are completely sealed. This is crucial to prevent the filling from escaping during baking. If the dough is sticky, you can lightly flour your fingers to help with sealing.)
Step 5: Combine melted butter, garlic powder, and Italian seasoning. Brush each dough ball with mixture. (In a small bowl, whisk together the melted butter, garlic powder, and Italian seasoning. This mixture adds a rich, savory flavor to the crust and helps it brown beautifully in the oven. Use a pastry brush to generously brush each pizza bomb with the seasoned butter.)
Step 6: Place pizza bombs sealed-side down on baking sheet. Bake 12-15 minutes until golden brown. (Arrange the pizza bombs on the prepared baking sheet, placing them sealed-side down. This helps to prevent the seams from opening up during baking. Bake for 12-15 minutes, or until the crust is golden brown and the cheese is melted and bubbly. Keep a close eye on them during the last few minutes of baking to prevent burning.)
Step 7: Serve warm with marinara or pizza sauce for dipping. (Let the pizza bombs cool slightly before serving. Serve them warm with your favorite marinara or pizza sauce for dipping. You can also offer other dipping sauces, like pesto, ranch, or even a spicy sriracha mayo, for added variety.)
