Preheat oven to 425°F and line a large baking sheet with parchment paper.
Pat the chicken wings completely dry with paper towels to ensure the skin gets maximum crispiness in the oven.
In a large bowl, toss the wings with avocado oil, sea salt, black pepper, garlic powder, and smoked paprika until every wing is evenly coated.
Arrange the wings in a single layer on the prepared baking sheet, ensuring they are not touching, and roast for 25-30 minutes, flipping halfway through.
While the wings roast, whisk together the tomato paste, apple cider vinegar, maple syrup, cayenne pepper, and coconut aminos in a small saucepan over low heat until the sauce thickens and becomes glossy.
Remove the wings from the oven and transfer them to a clean bowl, then pour the spicy BBQ glaze over them and toss until fully coated.
Place the coated wings back onto the baking sheet and roast for an additional 5 minutes to allow the glaze to caramelize and become sticky.
Serve the wings immediately while hot and crispy with the fresh celery stalks on the side for a cooling crunch.
