Adjust oven racks to upper-middle and lower-middle positions and preheat to 250°F. Set a wire rack into an foil lined rimmed baking sheet. Pat the wings dry with paper towels and place into a large ziplock bag. Combine the baking powder and salt and add to the bag. Seal and toss to evenly coat.
Arrange the wings, skin side up, in a single layer on the rack. Bake on the lower rack for 30 minutes and then move the wings to the upper rack. Increase the temperature to 425°F and roast until golden brown and crispy, 40-50 minutes. Rotate the sheet halfway through baking. Remove from the oven and let stand for 5 minutes before transferring to a large bowl and tossing with wing sauce. Enjoy hot.
Stir together the ingredients in a bowl until throughly mixed.
Note: The key to these crispy oven baked wings is the baking power and salt. The salt breaks down the proteins in the skin and the baking powder helps with browning. Starting the wings at a low temperature renders out the fat without overcooking and finishing at a higher temperature crisps and browns the skin.
