Making Pepperoni Pizza Sliders is a breeze. Just follow these simple steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C).
2. Prepare the Baking Dish: Lightly grease a 9×13 inch baking dish with cooking spray or butter.
3. Slice the Buns: Carefully slice the slider buns in half horizontally, keeping them connected. Place the bottom halves in the baking dish.
4. Spread Pizza Sauce: Evenly spread the pizza sauce over the bottom halves of the buns.
5. Add Cheese: Sprinkle half of the shredded mozzarella cheese over the sauce.
6. Layer Pepperoni: Arrange the slices of pepperoni on top of the cheese.
7. Add More Cheese: Sprinkle the remaining mozzarella cheese over the pepperoni.
8. Top with Bun Halves: Place the top halves of the slider buns on top of the cheese.
9. Prepare Butter Mixture: In a small bowl, mix the melted butter, garlic powder, and Italian seasoning.
10. Brush the Mixture: Brush the butter mixture generously over the tops of the slider buns.
11. Sprinkle Parmesan: If desired, sprinkle grated Parmesan cheese over the top for added flavor.
12. Bake: Cover the dish with aluminum foil and bake for 15 minutes. Then, remove the foil and bake for an additional 5-10 minutes, or until the tops are golden and the cheese is bubbly.
13. Cool Slightly: Remove the sliders from the oven and let them cool for a few minutes.
14. Slice and Serve: Using a sharp knife, slice the sliders into individual portions and serve warm.
