Preheat your oven to 400°F (200°C) and line a large rimmed baking sheet with parchment paper or a silicone mat.
Pat the chicken wings thoroughly dry with paper towels; removing moisture is the secret to achieving a crispy skin without deep frying.
In a large mixing bowl, combine the chicken wings with avocado oil, smoked paprika, garlic powder, onion powder, sea salt, black pepper, and cayenne pepper.
Toss the wings until they are evenly coated in the oil and spice mixture.
Arrange the wings in a single layer on the prepared baking sheet, ensuring they are not touching to allow for proper air circulation.
Bake for 35 to 40 minutes, flipping the wings halfway through the cooking time, until the skin is golden brown and crispy.
While the wings bake, slice the celery stalks into sticks.
Transfer the baked wings to a clean bowl, add the low-sugar BBQ sauce, and toss until every wing is well-glazed.
Return the wings to the baking sheet and bake for an additional 2 to 3 minutes to allow the sauce to become tacky and slightly caramelized.
Serve the hot wings immediately alongside the fresh celery sticks.
