Preheat your oven to 375°F (190°C) to ensure even baking and golden brown roll-ups.
In a mixing bowl, combine the cooked chopped chicken, ranch dressing, and 3 tablespoons of buffalo hot sauce. Stir in the shredded cheddar cheese until well mixed.
In a separate bowl, whisk together the cream of chicken soup and milk until smooth to create a creamy sauce.
Open the cans of crescent rolls. On a lightly floured surface, lay out the larger 8-count crescent rolls first. Pinch the seams together to form a solid sheet.
Spread half of the creamy sauce over the dough, then evenly distribute the chicken mixture over the top.
Drizzle the remaining buffalo hot sauce over the chicken mixture, then carefully roll the dough up starting from the long edge. Pinch the ends to seal.
Repeat the rolling process with the smaller 4-count crescent rolls using the remaining filling and sauce. Bake separately or alongside the larger rolls.
Place the roll-ups on a baking sheet lined with parchment paper. Bake for 15-20 minutes until golden brown and heated through.
Remove from oven and let cool a few minutes. Serve with additional ranch dressing and your favorite dipping sauces. Enjoy!
