Follow these straightforward steps to create your Pepperoni Pizza Puffs:

1. Preheat Oven: Preheat your oven to 375°F (190°C). Prepare a baking sheet by lightly greasing it with cooking spray.
2. Prepare Dough: Unroll the crescent roll dough onto a clean surface. Pinch the seams together to form a single sheet.
3. Cut Dough into Squares: Use a knife or pizza cutter to slice the dough into approximately 3-inch squares.
4. Add Filling: In each square, place about 1 tablespoon of pizza sauce, followed by 2 tablespoons of mozzarella cheese, and a few pieces of pepperoni. Sprinkle a little Italian seasoning if desired.
5. Fold the Puffs: Gently bring the corners of each square together, pinching the edges to seal each puff tightly.
6. Apply Egg Wash: In a small bowl, beat the egg and brush it over the tops of the puffs for a golden finish.
7. Bake: Place the assembled puffs on the prepared baking sheet and bake for 15-20 minutes or until golden brown.
8. Cool Slightly: Once baked, remove the puffs from the oven and let them cool for a few minutes.
9. Serve with Dipping Sauce: Transfer the puffs to a serving platter and accompany with extra pizza sauce for dipping.

By following these simple steps, you’ll have a batch of Pepperoni Pizza Puffs ready to impress!
