Preheat your oven to 375°F (190°C).
In a mixing bowl, combine softened cream cheese, crumbled bacon, shredded cheddar cheese, garlic powder, onion powder, salt, and pepper. Mix thoroughly until well combined.
Take each chicken breast and create a pocket by cutting horizontally into each breast, being careful not to cut all the way through.
Stuff each chicken breast pocket with the cream cheese mixture, pressing it down gently to fit. Secure with toothpicks if necessary.
In a frying pan, heat the olive oil over medium heat. Add the stuffed chicken breasts and sear for about 2-3 minutes per side until they are golden brown.
Transfer the chicken breasts to a baking dish and sprinkle the crushed Doritos evenly over the top.
Bake in the preheated oven for 25-30 minutes until the chicken is cooked through (internal temperature should reach 165°F or 75°C).
Remove from the oven, let rest for 5 minutes, and then serve hot.
