Preheat oven to 400°F (200°C).
Line a baking sheet with parchment paper.
Place small mounds of shredded mozzarella on the baking sheet, flattening them slightly.
Top each mound with a pepperoni slice.
Bake for 5-7 minutes or until the edges are golden and crispy.
Allow to cool slightly before serving. Enjoy on their own or with a side of marinara sauce!
