Add chicken to slow cooker
Place the chicken breasts in the bottom of the slow cooker.
Add the creamy ingredients
Add the cream cheese, buffalo sauce, ranch seasoning, chicken broth, garlic powder, and black pepper on top of the chicken.
Slow cook
Cover and cook on LOW for 4 to 5 hours or HIGH for 2 to 3 hours, until the chicken is fully cooked and easy to shred.
Shred the chicken
Use two forks to shred the chicken directly in the slow cooker.
Stir everything together
Mix the shredded chicken well with the cream cheese and sauce until creamy and fully combined.
Add cheese and bacon
Stir in the shredded cheddar cheese and most of the crumbled bacon. Save a little bacon for topping.
Finish and serve
Cover for 5 to 10 minutes so the cheese melts completely. Top with green onions and remaining bacon before serving.
