In a mixing bowl, combine the ranch seasoning mix with the hot sauce until well blended.
Place the chicken breasts in the bottom of a Crock-Pot
Cut the butter into small pieces and scatter them over the chicken.
Pour the hot sauce mixture over the chicken and butter in the Crock-Pot.
Cover the Crock-Pot with its lid and set to cook on low heat for 4 hours.
After 4 hours, check if the chicken is tender enough to shred with two forks. If not, cook a bit longer until it reaches the desired tenderness.
Shred the chicken inside the Crock-Pot and stir to combine with the sauce.
Serve the Buffalo chicken on sandwiches, as a topping for nachos or salads, inside quesadillas, or use it as a dip with crackers and chips.
