Preheat oven to 400°F (200°C). Line a baking sheet with parchment paper.
In a shallow dish, combine flour, Parmesan cheese, garlic powder, onion powder, salt, and pepper. Dip each chicken breast into the mixture, turning to coat evenly.
Place the chicken breasts on the prepared baking sheet and bake for 15-20 minutes, or until cooked through.
In a saucepan, melt butter over medium heat. Whisk in heavy cream, garlic, salt, and pepper. Cook and stir until sauce is smooth and slightly thickened.
Arrange the baked chicken breasts on plates and drizzle generously with the Creamy Garlic Sauce.
