01 - Preheat oven to 375°F. Grease a 9x13-inch baking dish with butter or non-stick spray.
02 - Using a bread knife, slice the slider buns horizontally in one piece, 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 mozzarella cheese over the sauce layer.
04 - Arrange pepperoni slices in a single, even layer over the mozzarella. Top with the remaining mozzarella cheese.
05 - Place the top slab of buns over the layered filling, pressing down gently.
06 - In a small mixing bowl, combine melted butter, honey, hot sauce, garlic powder, and dried Italian herbs. Brush the mixture generously over the tops of the buns using a pastry brush.
07 - Sprinkle grated Parmesan cheese and a pinch of red pepper flakes over the glazed tops.
08 - Cover loosely with aluminum foil and bake for 15 minutes. Remove the foil and continue baking for an additional 5 minutes until the cheese is fully melted and the tops are golden brown.
09 - Allow sliders to cool for 2 to 3 minutes. Garnish with fresh chopped basil if desired. Slice along roll boundaries and serve warm.
