Preheat the oven to 375°F (190°C).

In a mixing bowl, combine cream cheese, spinach, cheddar cheese, garlic powder, onion powder, salt, and pepper.

Slice a pocket into each chicken breast and stuff with the cream cheese mixture.

Wrap each stuffed chicken breast with bacon slices.

Place the wrapped chicken in a baking dish.

Bake in the preheated oven for 30 minutes or until the chicken is cooked through.

Let it rest for a few minutes before serving.
