01 - Preheat oven to 375°F. Grease a 9x13-inch baking dish with butter or non-stick spray.
02 - Slice the slider buns horizontally in one piece to create a connected top and bottom slab, keeping the 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 assembled 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 and sides of the buns using a pastry brush.
07 - Sprinkle grated Parmesan cheese and red pepper flakes evenly over the brushed buns.
08 - Cover the dish loosely with aluminum foil. Bake for 15 minutes.
09 - Remove the foil and continue baking for an additional 5 minutes, or until the cheese is fully melted and the tops are golden brown.
10 - Let rest for 2 to 3 minutes. Garnish with fresh chopped basil if desired. Slice along the roll seams into individual sliders and serve warm.
