Preheat oven to 375°F (190°C). Cut a pocket into each chicken breast, season with salt and pepper.
In a bowl, combine cream cheese, cheddar, bacon, ranch, garlic powder, onion powder, smoked paprika, salt, and pepper until creamy.
Fill each chicken pocket with the mixture and secure with toothpicks if needed.
Crush Doritos in a zip-top bag and press onto the chicken to coat.
Heat olive oil in an oven-safe skillet, sear chicken for 2–3 minutes per side until golden, then bake for 20–25 minutes or until it reaches 165°F (75°C).
Remove toothpicks, slice, and serve warm with the creamy filling and crisp Dorito crust.
