01 - Preheat the oven to 350°F. Lightly grease a 9x13-inch baking dish with butter or nonstick spray.
02 - Using a serrated knife, slice the slider buns in half horizontally while keeping them connected as a sheet. Place the bottom halves in the prepared baking dish.
03 - Spread the marinara sauce evenly across the bottom bun halves. Sprinkle half of the mozzarella over the sauce, then layer the pepperoni slices on top. Add the remaining mozzarella and scatter the dried Italian herbs over the cheese.
04 - Place the top halves of the buns over the layered fillings, pressing down gently to help the sliders hold together.
05 - Combine the melted butter with the garlic powder. Brush the mixture generously over the tops of the buns. Sprinkle with grated Parmesan and chopped parsley if desired.
06 - Cover the baking dish tightly 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.
07 - While the sliders bake, gently warm the honey in a small saucepan over low heat or in a microwave-safe bowl in 15-second intervals. Stir in the hot sauce until well blended. Keep warm until ready to serve.
08 - Remove the sliders from the oven and let them rest for 2 minutes. Use a serrated knife to cut along the bun seams into individual sliders. Drizzle the warm hot honey over the tops just before serving.
