Preheat your smoker to 225°F (107°C). If using a charcoal smoker, add wood chips for flavor, such as hickory or applewood.
In a large bowl, combine olive oil, smoked paprika, garlic powder, onion powder, cayenne pepper, salt, black pepper, and brown sugar. Mix well to create a flavorful marinade.
Add the chicken wings to the marinade, ensuring they are evenly coated. For best results, allow the wings to marinate in the refrigerator for at least 1 hour, or overnight for deeper flavor.
Once the smoker is preheated, arrange the marinated wings on the smoker rack, leaving space between each wing for even cooking.
Smoke the wings for 1.5 to 2 hours, or until they reach an internal temperature of 165°F (74°C). For extra crispiness, consider increasing the smoker temperature to 375°F (190°C) for the last 15 minutes of cooking.
If desired, brush the wings with barbecue sauce during the last 10 minutes of smoking for a sticky glaze.
Remove the wings from the smoker and let them rest for a few minutes before serving. Enjoy!
