Method
Preparation
In a bowl, mix the sourdough starter, flour, salt, and garlic powder until combined. Use a spoon to bring the mixture together gently.
Knead the dough for about 5 minutes on a lightly floured surface until it becomes smooth and elastic.
Let the dough rise in a warm place for 1–2 hours until doubled in size. Cover the bowl with a clean towel or plastic wrap.
Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper.
Assembly
Once the dough has risen, punch it down and divide it into small pieces (about the size of a golf ball).
Flatten each piece and place a small amount of mozzarella cheese, pepperoni, and a sprinkle of Italian seasoning in the center.
Fold the dough over the filling and pinch to seal, ensuring no gaps are present.
Place the filled dough balls seam-side down on the prepared baking sheet, spaced an inch apart.
Brush the tops with olive oil.
Baking
Bake for 15–20 minutes, or until golden brown.
After baking, let cool for a couple of minutes before serving. Serve hot with marinara sauce for dipping.
Notes
Freeze baked bombs in an airtight container for up to 2 months. Make sure to reheat properly to maintain texture.
