Preheat the oven to 375°F (190°C) and line a baking sheet with parchment paper.
Place small mounds of shredded mozzarella cheese on the baking sheet, spacing them a few inches apart.
Top each cheese mound with a slice of pepperoni.
Bake for 5-7 minutes, or until the cheese is melted and crispy around the edges.
Remove from the oven and let cool slightly before serving. Enjoy!
