Preheat oven to 350 degrees and lightly grease a 9x9 baking dish.
Slice Hawaiian rolls open and place bottom halves in the baking dish.
Add shredded chicken to a medium bowl. If using prepared shredded chicken from the refrigerator, warm it up in the microwave for about 1 minute, stirring halfway through.
Prepare the Buffalo Sauce: Add melted butter, Frank's Red Hot, and ranch dressing to a small bowl and mix thoroughly to combine. Microwave for 5 to 10 seconds if needed to fully incorporate.
Pour Buffalo Sauce over the chicken. Stir well to combine, fully coating the chicken in sauce, then stir in shredded cheddar.
Spread the chicken evenly over the Hawaiian rolls.
Top sliders with sliced American cheese, then place the tops of the Hawaiian rolls on the sliders.*
Cover the pan with foil and bake for 30 minutes.
Serve hot with your favorite side!*
