In a slow cooker, add the chicken breasts in a single layer. Pour the buffalo sauce over top of the chicken. Cover and cook on high for 1 1/2 hours, or until the internal temperature of the chicken reaches above 165 degrees.
Once the chicken is cooked, transfer the chicken breasts to a cutting board and shred with two forks. Add the shredded chicken back to the slow cooker.
To the slow cooker, add the rest of the dip ingredients. Stir to combine.
Cover and cook on high for 30 more minutes, or until the cheese and cream cheese has melted.
