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 2 slices of bacon.

Place the wrapped chicken breasts in a baking dish.

Bake in the preheated oven for 30-35 minutes or until the chicken is cooked through.

Let rest for a few minutes before slicing and serving.
