Preheat oven to 375°F. Combine mayonnaise, TABASCO® Sauce and onion powder in a small bowl; stir until well blended. Place cereal in a plastic bag and seal; finely crush cereal with hands. Add parsley, if desired.
Brush chicken generously with mayonnaise mixture. Add one piece of chicken at a time to crushed corn flakes and shake to coat well; repeat with remaining chicken. Bake on an ungreased shallow baking pan for 45 minutes or until chicken is crisp, tender and no longer pink inside.
