Line a rimmed baking sheet with foil then set a wire rack inside and spray rack with cooking spray.
Dry chicken wings thoroughly with paper towels to remove as much moisture as possible.
Mix baking powder, salt, onion powder, garlic powder, and pepper in a large bowl or zip to plastic bag then add chicken wings and toss to coat.
Place wings on rack leaving about 1 inch of space in between each wing.
Bake wings for 20 minutes then flip and bake for an additional 20 minutes.
Flip again and bake for about 5 more minutes until the wings are cooked through and skin is crispy and light golden brown.
Remove from oven and allow to cool for about 5 minutes.
While the wings cool melt the butter in a microwave safe dish and then add to a large bowl with the hot sauce and stir to combine.
Add cooled wings to the bowl with the sauce and toss until thoroughly coated.
This recipe is for about medium level heat. If you want more heat you can reduce the amount of butter to 1- 2 tsp and increase the amount of hot sauce or try a brand or hot sauce with higher heat. You can also try adding cayenne pepper to the mixture.
