In large bowl, beat brown sugar, salt and beer with whisk. Add chicken wings; toss gently to coat. Refrigerate 30 minutes to brine.
In large resealable food-storage plastic bag, mix onion powder, garlic powder and paprika. Drain chicken; pat dry with paper towels. Discard brine. Add chicken to bag; toss until evenly coated. Place chicken on cookie sheet.
In 1-quart saucepan, melt butter. Stir in pepper sauce. Heat to a simmer. Pour mixture over wings.
Bake 30 to 35 minutes or until juice of chicken is clear when thickest part is cut to bone (165°F). If desired, shake extra pepper sauce over wings after baking.
