Preheat the oven to 450F.
Line a baking sheet with tin foil and place a fitted wire cooling rack on top (see note for link). If you don’t have a wire rack that fits on your baking sheet, you can just line the baking sheet with parchment and cook the wings directly on there.
Add the wings to a large bowl and use paper towels to pat as dry as you can (this is important for crispy skin, see note). Add the baking powder and salt and toss to coat. Arrange them evenly on the baking sheet.
Bake for 20 minutes, then flip them over and bake for 10-20 more minutes or until the skin is crisp and golden and the chicken is cooked through. Wings can vary a lot in size, so use your judgement.
Meanwhile, choose the sauce you want to make and whisk the ingredients together in your biggest bowl. See note for buffalo sauce instructions.
Once the wings are done, add them to the bowl with the sauce and toss to coat well. Serve immediately as is or with a side of ranch or thinned out yogurt for dipping!
