In a flat bowl, mix flour, cayenne pepper, black pepper, garlic powder, onion powder, paprika, and salt.
Whisk the egg in a separate bowl.
Dip each chicken drumstick in the egg wash, then coat with the flour mixture, ensuring even coverage.
Place coated drumsticks in the melted butter in the baking dish.
Bake at 425°F (218°C) for about an hour, flipping the drumsticks over after 30 minutes.
