Creating Pepperoni Pizza Sliders is straightforward. Follow these steps for a delicious result:

1. Preheat your oven to 350°F (175°C).
2. Prepare the baking dish: Grease a 9×13-inch baking dish gently with cooking spray or butter.
3. Assemble the buns: Slice the slider buns in half horizontally and place the bottom halves in the prepared baking dish.
4. Add sauce: Spread a generous layer of marinara sauce over the buns.
5. Layer ingredients: Sprinkle half of the shredded mozzarella cheese over the sauce, then evenly distribute the pepperoni slices on top.
6. Top with cheese: Finish with the remaining mozzarella cheese.
7. Cover with the top buns: Place the top halves of the sliders on the cheese layer.
8. Prepare the butter sauce: In a bowl, combine the melted butter, garlic powder, and Italian seasoning. Mix well.
9. Brush the mixture: Drizzle the butter mixture over the top of the slider buns, ensuring they are evenly covered.
10. Add Parmesan: If desired, sprinkle grated Parmesan cheese on top for additional flavor.
11. Bake: Cover the dish with aluminum foil and bake for 20 minutes. Remove the foil and bake for an additional 5-10 minutes or until the tops are golden and crispy.
12. Cool slightly: Once out of the oven, let the sliders cool for a few minutes before slicing.
