Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper or a wire rack for extra crispiness.
Pat the chicken wings thoroughly dry with paper towels to remove excess moisture.
In a large bowl, toss the wings with avocado oil, sea salt, black pepper, garlic powder, and smoked paprika until evenly coated.
Arrange the wings in a single layer on the prepared baking sheet, ensuring they are not touching.
Bake for 35 to 40 minutes, flipping the wings halfway through, until the skin is golden brown and crispy.
While the wings bake, whisk together the sugar-free BBQ sauce and hot sauce in a clean bowl.
Once the wings are finished, remove them from the oven and immediately toss them in the spicy BBQ sauce mixture.
Serve the wings hot alongside the fresh celery and carrot sticks.
