Preheat oven to 425F. Add an oven-safe baking wire rack to a large, rimmed sheet pan. Set aside.
In a small bowl, combine the sugar and lemon zest. Rub together with your fingers to release the lemon essential oils. Add the flour, BBQ seasoning, paprika, garlic powder, salt, and baking powder. Mix well.
Add the chicken wings to a large bowl, try not to transfer over any chicken juice from the packaging. Add the seasoning mixture and toss until well coated.
Evenly distribute on the wire rack. Pat in any extra dry rub at the bottom of the bowl into any bare spots on the chicken wings. Bake 30-40 minutes, until deeply golden and crispy. Flip the chicken wings every 15 minutes.
