In a small mixing bowl, combine the smoked paprika, garlic powder, onion powder, brown sugar, salt, black pepper, and cayenne pepper. Mix well until all the ingredients are evenly distributed.
Transfer the mixture to an airtight container, such as a small jar, and store it in a cool, dry place until ready to use.
To use the seasoning, simply sprinkle it over chicken before grilling or baking. Ensure the chicken is coated evenly for optimal flavor.
