Get ready for an all-star cupcake showdown as Mel B, Mayim Bialik, Andy Dick and Jennie Garth battle to prove their baking dominance and have their cupcakes featured at an epic party celebrating the first and most famous video game platform of all time: Atari! These four might be VIPs in the real world, but they'll face the same Cupcake Wars gauntlet as any other baker and be eliminated one by one with the help of guest judge and CEO of Atari, Fred Chesnais. The last celebrity standing earns bragging rights and a donation to their charity of choice.
