What happened: The dessert pairs a chocolate brownie with soft serve, banana, licorice ropes, whipped cream and cherries. It is served in a souvenir helmet for postseason home games.

Why it matters: Postseason concession launches are timed to October home dates at Rate Field. The sundae follows the club's two-pound Fall Classic Burger rollout.

What to watch: Availability continues through remaining White Sox home postseason games.
