Preheat the oven to 200°F (about 95°C). Line a rimmed baking sheet with foil and place a wire cooling rack inside the sheet.
Pat the chicken wings dry with paper towels and place them in a large bowl.
In a small bowl, combine the paprika, light brown sugar, salt, black pepper, garlic powder, ground cumin, and cayenne (if using).
Sprinkle the seasoning mix evenly over the wings, then rub thoroughly so each wing is well coated.
Arrange the seasoned wings in a single layer on the wire rack, leaving space between pieces for air circulation.
Bake at 200°F for 1 hour 15 minutes. Then turn each wing over, increase the oven temperature to 250°F, and bake for another 1 hour 15 minutes.
Turn the wings again, raise the oven temperature to 300°F, and bake for an additional 30 minutes until the skin is crisp and the meat is cooked through.
Remove the wings from the oven and serve warm or at room temperature.
