Preheat the oven to 425°F (220°C).
Prepare the chicken wings by patting them dry with paper towels.
In a bowl, combine the baking powder, paprika, garlic powder, onion powder, cayenne pepper, black pepper, and salt.
Toss the dried wings in the spice mixture until well coated.
Place the wings on a wire rack set over a baking sheet.
Bake the wings in the preheated oven for 40-45 minutes, flipping halfway through.
Check for doneness; wings should be crispy and golden.
Allow the wings to rest for 5 minutes before serving.
