Preheat oven to 425˚F.
Line a baking sheet with foil or parchment paper, and lightly grease with cooking spray; set aside.
Separate the wings into three pieces; that is, cut every piece at the joint. Discard the wing tips. You can also buy precut chicken wings.
In a large bowl or ziploc bag combine flour, baking powder, onion powder, garlic powder, chili powder, salt, and pepper.
Add the wings to the flour mixture and toss around to coat the wings evenly.
Transfer wings to previously prepared baking sheet.
Bake for 40 minutes, flipping them halfway through cooking.
In the meantime prepare the Mango Habanero Sauce.
In a large cup or bowl whisk together the mango nectar, melted butter, Frank’s Hot Sauce, Chile Habanero sauce, and sugar; whisk until thoroughly combined.
Remove chicken wings from oven.
Add wings to the prepared sauce and toss around to coat.
Transfer wings to a serving platter.
Serve with celery sticks and bleu cheese dressing.
