Pre-heat your oven to 250 degrees. Line a baking sheet with foil and place a baking rack on top of the foil. Spray the rack with a cooking spray or brush with canola oil if you don't have spray.
Pat the wings dry (this is very important for crispy wings) and add them to a zip-top bag.
To the bag, add the baking powder, salt, and garlic powder. Close the bag and shake to coat the wings.
Place the wings on the oiled baking rack (skin side up) and place in the oven for 30 minutes.
After the 30 minutes, increase the temperature to 450 degrees. Cook for 45 minutes.
Making the sauce
Add the butter, garlic, and salt to a saucepan and cook on low until the butter is melted. (about 5 minutes)
Once melted, add the parmesan cheese and the parsley and stir to combine.
When the wings are done, remove from the oven and let them cool for about 5 minutes. .
Add the wings to a heat safe bowl. Pour the sauce over the wings and toss to coat. Serve immediately
