01 - Preheat oven to 400°F. Lightly grease a 9x13 inch baking dish with cooking spray or butter.
02 - In a skillet over medium heat, cook bacon slices until evenly crisp, about 4-5 minutes per side. Transfer to paper towels to drain, then crumble into small pieces once cooled.
03 - In a mixing bowl, combine 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 chicken breasts in the prepared baking dish. Spread the cream cheese mixture evenly over the top of each breast, covering the surface completely.
05 - Sprinkle the remaining cheddar cheese over the coated chicken, then distribute the crumbled bacon evenly across the top.
06 - Bake uncovered for 25-30 minutes, until the chicken reaches 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 if desired, then serve warm.
