01 - Preheat oven to 375°F. Grease a 9x13-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 individual rolls attached. Place the bottom slab into the prepared baking dish.
03 - Spread pizza sauce evenly across the bottom buns. Sprinkle half of the shredded mozzarella over the sauce layer.
04 - Arrange 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 assembled filling, pressing down gently to compress the layers.
06 - In a small mixing bowl, combine 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 grated Parmesan cheese and a pinch of red pepper flakes over the brushed bun tops.
08 - Cover the dish loosely with aluminum foil and bake for 15 minutes. Remove the foil and continue baking for 5 additional minutes, or until the cheese is fully melted and the tops are golden brown.
09 - Remove from oven and let rest for 2 to 3 minutes. Garnish with fresh chopped basil if desired. Slice along roll seams into individual sliders and serve warm.
