Preheat the oven to 200°F (95°C). Line a rimmed baking sheet with aluminum foil and place a wire cooling rack on top.
Pat the 3 pounds of chicken wings dry with paper towels and place them in a large bowl.
In a small bowl, combine 3 tablespoons paprika, 2 tablespoons light brown sugar, 1 tablespoon salt, 1/2 tablespoon black pepper, 1 teaspoon garlic powder, 1 teaspoon ground cumin, and 1/4 teaspoon cayenne (if using).
Sprinkle the seasoning mixture evenly over the wings and rub thoroughly so each piece is coated. Arrange the wings in a single layer on the wire rack.
Bake at 200°F for 1 hour and 15 minutes.
Turn the wings, increase the oven temperature to 250°F, and bake for another 1 hour and 15 minutes.
Turn the wings again, raise the oven to 300°F, and bake for an additional 30 minutes until the skin is crisp and browned.
Remove from the oven and serve warm or at room temperature.
