Preheat oven to 375°F (190°C). Lightly grease a baking dish with cooking spray or oil.

In a bowl, mix cream cheese, cheddar cheese, bacon, garlic powder, onion powder, paprika, and black pepper until creamy and well combined.

Cut a pocket into each chicken breast without slicing all the way through. Fill each pocket with the cheese and bacon mixture, securing with toothpicks if necessary.

Roll the stuffed chicken breasts in crushed Doritos, pressing gently to coat all sides.

Place in the prepared baking dish and bake for 25–30 minutes, or until chicken is cooked through and reaches an internal temperature of 165°F (74°C).

Let the chicken rest for a few minutes before serving.
