01 - Preheat the oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter or nonstick spray.
02 - Using a serrated bread knife, slice the slider buns horizontally in one piece to create a top and bottom slab, keeping the individual rolls attached. Place the bottom slab in the prepared baking dish.
03 - Spread the pizza sauce evenly across the bottom buns. Sprinkle half of the shredded mozzarella over the sauce in an even layer.
04 - Arrange the pepperoni slices in a single, even layer over the mozzarella. Top with the remaining shredded mozzarella.
05 - Place the top slab of buns over the layered filling, pressing down gently to secure.
06 - In a small mixing bowl, combine the melted butter, honey, hot sauce, garlic powder, and dried Italian herbs. Brush the mixture generously and evenly over the tops of the buns using a pastry brush.
07 - Sprinkle the grated Parmesan cheese and a pinch of red pepper flakes over the glazed tops.
08 - Cover the dish loosely with aluminum foil and bake for 15 minutes. Remove the foil and continue baking for an additional 5 minutes, or until the cheese is fully melted and the tops are golden brown.
09 - Allow the sliders to cool for 2–3 minutes. Garnish with chopped fresh basil if desired. Slice along the bun seams and serve warm.
