Preheat & Prep: Heat the oven to 350°F and line a 9×9 baking sheet or casserole dish with parchment paper.
Mix the Filling: In a bowl, combine shredded chicken, buffalo hot sauce, ranch dressing, salt, pepper, garlic powder, and paprika.
Assemble the Sliders: Place the bottom halves of the slider buns on the baking sheet. Evenly distribute the buffalo chicken mixture on each bun.
Layer the Cheese: Sprinkle shredded cheese on top of the buffalo chicken mixture, then place the top buns over the cheese.
Brush with Garlic Butter: In a small bowl, mix melted butter, garlic powder, and Italian seasoning. Brush this over the tops of the slider buns.
Bake to Perfection: Cover the baking sheet with foil and bake for 15 minutes. Remove the foil and bake for an additional 5-10 minutes until the tops are golden brown and the cheese is melted.
Serve & Enjoy: Slice the sliders apart and serve hot with your favorite sides.
