Preheat the oven to 375°F (190°C) and grease a baking dish.
In a bowl, mix the softened cream cheese, shredded cheese, and green onions.
Cut a pocket into each chicken breast and fill with the cream cheese mixture. Secure with toothpicks if necessary.
Crush the Doritos into crumbs using a plastic bag and rolling pin or a food processor.
Season the chicken with garlic powder and onion powder, then coat with the crushed Doritos.
Place the chicken in the baking dish and bake for 25-30 minutes until cooked through.
Let rest for a few minutes, remove toothpicks, and serve warm. Enjoy!
