If not already done, cut the wings into drumettes and flats. Using paper towels, pat dry each wing (helps crispiness!).
In a large bowl, gently toss the chicken wings with avocado oil.
In a small bowl, whisk together the salt, black pepper, baking powder, smoked paprika, garlic powder, onion powder, ground mustard, and cayenne pepper (if using).
Sprinkle the seasoning mix over the chicken wings and toss.
