Preheat the oven to 400°F and line a baking sheet with parchment paper.
In a large mixing bowl, combine the melted butter, hot sauce, garlic powder, salt, and black pepper. Mix well.
Add the chicken wings to the bowl and toss until evenly coated with the sauce.
Arrange the chicken wings in a single layer on the prepared baking sheet.
Bake the wings for 40-45 minutes, or until the skin is crispy and golden brown, flipping halfway through.
Remove the wings from the oven and sprinkle with grated parmesan cheese.
Place the wings back in the oven for an additional 3-5 minutes, or until the cheese is melted and bubbly.
Garnish with chopped parsley (optional) and serve hot. Dig in!
