1. 1. Prepare the Chicken Mixture: In a medium bowl, combine the cooked, shredded chicken with the buffalo wing sauce and ranch dressing. Stir everything together until the chicken is thoroughly coated. The mixture should look moist and evenly orange from the sauce.

2. 2. Preheat and Slice Buns: Preheat your oven to 350 F (175 C). Take your package of dinner rolls or slider buns and, without separating them, slice the entire slab of rolls horizontally through the middle, creating a top and bottom half. Place the bottom halves of the rolls into a 9×13 inch baking dish.

3. 3. Assemble the Filling: Spread the buffalo chicken mixture evenly over the bottom layer of the rolls in the baking dish. Make sure the chicken goes right to the edges for full flavor in every bite.

4. 4. Add the Cheese Layer: Sprinkle the shredded cheddar cheese generously over the buffalo chicken mixture. You want a good, even layer of cheese that will melt into gooey deliciousness.

5. 5. Place Top Buns: Carefully place the top halves of the rolls back over the cheese layer, aligning them with the bottom halves.

6. 6. Prepare the Butter Topping: In a small microwave-safe bowl, melt the unsalted butter. Stir in the garlic powder and dried parsley flakes (if using). This creates a savory, fragrant topping for the buns.

7. 7. Brush and Bake: Brush the melted garlic butter mixture evenly over the tops of the slider buns. Cover the baking dish loosely with aluminum foil. Bake for 15 minutes, then remove the foil and bake for an additional 5-10 minutes, or until the cheese is bubbly and melted, and the tops of the buns are lightly golden brown.

8. 8. Serve Warm: Once baked, remove the dish from the oven. Let it cool for a few minutes before slicing along the original bun lines to separate the sliders. Serve immediately while warm and gooey.
