Line a rimmed baking sheet with foil and set a wire rack on top. Pat the wings completely dry with paper towels.
Combine the baking powder, salt, garlic powder, onion powder, paprika, and pepper. Toss the wings in the dry rub until evenly coated.
Air Chill:
Arrange the wings in a single layer on the rack. Refrigerate uncovered for at least 1 hour, up to 8 hours. Do not cover.
Bake:
Preheat oven to 425°F. Transfer the baking sheet to the oven and bake 40 to 50 minutes, flipping halfway, until the skin is deep golden brown and the internal temp reads 165°F.
Make the Sauce:
Add mango, habanero peppers, garlic, apple cider vinegar, lime juice, and salt to a blender. Blend until completely smooth.
Pour into a small saucepan over medium heat, stir in the honey, and simmer 10 minutes, stirring frequently, until slightly thickened. Remove from heat and whisk in the butter.
Sauce and Serve:
Optional: broil the wings 2 minutes for extra char.
Transfer hot wings to a large bowl, pour sauce over, and toss with tongs until coated. Garnish with minced parsley or sliced scallions.
Notes
Use aluminum-free baking powder to avoid a metallic aftertaste
Wear gloves when handling habaneros
For a glossy sauce, strain through a fine-mesh sieve after blending
Sauce keeps in a sealed jar in the refrigerator for up to 1 week
Reheat leftovers at 350°F for 10-12 minutes to re-crisp the skin
