Mix flour, parmesan, paprika, garlic powder, salt, and pepper in a second bowl.
Dip chicken, 1 breast at a time, in egg mixture, then in parmesan/paprika mixture, turning to evenly coat both sides of each breast with each ingredient.
Place on prepared baking sheet, in a single layer.
Pour the melted butter evenly over the chicken.
Bake for about 40-45 minutes in the preheated oven, until the cheese has browned, and the chicken has cooked.
