Preheat the oven to 400°F (200°C) and line a baking sheet with parchment paper or foil.
In a mixing bowl, combine the baking powder, salt, garlic powder, onion powder, smoked paprika, black pepper, chili pepper, and brown sugar.
Add the chicken wings to the bowl and toss thoroughly with the dry rub until evenly coated.
Arrange the seasoned wings in a single layer on the prepared baking sheet and drizzle evenly with the olive oil.
Bake the wings for 35 minutes, or until the internal temperature reaches 165°F (74°C) and the skin is crisp to your liking.
Remove from oven, let rest a few minutes, then serve.
