01 - Preheat your oven to 375°F (190°C). Grease a 9x13-inch baking dish.
02 - Slice the slider buns horizontally to create a top and bottom slab, keeping the individual rolls attached. Place the bottom slab in the prepared baking dish.
03 - Evenly spread the pizza sauce over the bottom buns. Sprinkle half of the mozzarella over the sauce.
04 - Arrange the pepperoni slices in a single layer over the cheese. Sprinkle the remaining mozzarella on top.
05 - Place the top slab of buns over the filling.
06 - In a small bowl, mix the melted butter, honey, hot sauce, garlic powder, and Italian herbs. Brush this mixture generously over the tops of the buns.
07 - Sprinkle grated Parmesan and a pinch of red pepper flakes (if using) over the tops.
08 - Cover loosely with foil and bake for 15 minutes. Remove foil and bake an additional 5 minutes, or until cheese is melted and tops are golden brown.
09 - Let cool slightly. Garnish with fresh basil if desired. Slice along the bun seams into individual sliders and serve warm.
