Pre-heat your oven to 350 degrees and spray a 13×9 baking dish with cooking spray.
Using a serrated knife, slice the mini buns in half (without separating them) so there is a sheet of bottoms and a separate sheet of tops.
Place the bottoms into the pan and bake for 5 mins.
While bottoms are toasting, peel all of the rotisserie chicken off of the bones and place it into a bowl. Use a hand mixer set to medium to shred the chicken.
Mix together shredded chicken, buffalo sauce, and 1 tablespoon of ranch seasoning.
In a separate bowl, melt butter and add 1 tablespoon of ranch seasoning.
Once bottoms are done baking, spread a thin layer of ranch dressing over them.
Then top the bottoms with the chicken mixture and then sprinkle that with cheese.
Place the sheet of bun tops onto the sliders and brush the ranch-butter mixture on top of all the buns.
Bake for 10-15 mins, enjoy while warm!
