01 - Preheat oven to 400°F. Lightly grease a baking dish with non-stick spray or butter.
02 - In a skillet over medium heat, cook the bacon slices until evenly crisp. Transfer to paper towels to drain, then crumble into small pieces once cooled.
03 - In a mixing bowl, combine the softened cream cheese, sour cream, ranch seasoning, garlic powder, black pepper, and half of the shredded cheddar cheese. Stir until smooth and well blended.
04 - Arrange the chicken breasts in the prepared baking dish. Spread the cream cheese mixture evenly over the top of each breast.
05 - Sprinkle the remaining cheddar cheese and crumbled bacon over the coated chicken breasts.
06 - Bake for 25 to 30 minutes, or until the chicken is cooked through to an internal temperature of 165°F and the cheese is bubbling and golden on top.
07 - Remove from the oven and let rest for 5 minutes. Garnish with chopped chives or green onions before serving, if desired.
