Put boneless skinless chicken breasts at the bottom. Cut cream cheese blocks in half and put on top of meat. Sprinkle in ranch seasoning, Add cheese on top of everything.
Cook on low for 6 hours or until meat shreds easily with 2 forks. When time is up use two forks to shred chicken and stir all ingredients together so chicken is nice and coated. (if it shreds super easy with forks it is done, if breasts are thick and it is a bit tough then leave in for more time) Add bacon if you'd like now.
