1. Preheat the oven:
- Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper or a silicone baking mat.
2. Prepare the cheese mixture:
- In a bowl, mix the shredded mozzarella, grated Parmesan, Italian seasoning, garlic powder, and red pepper flakes (if using).
3. Assemble the chips:
- Scoop heaping tablespoons of the cheese mixture onto the prepared baking sheet, spacing them about 2 inches apart. Flatten each scoop slightly into a small circle.
- Top each cheese circle with 2–3 mini pepperoni slices or a small amount of chopped pepperoni.
4. Bake the chips:
- Bake in the preheated oven for 8–10 minutes, or until the edges are golden and crispy.
5. Cool the chips:
- Remove from the oven and let the chips cool on the baking sheet for 5 minutes. They will crisp up further as they cool.
6. Serve:
- Serve warm with pizza sauce or marinara on the side for dipping, if desired.
