The Yellow Cake Batter Classic Shake consists of a blend of vanilla ice cream and yellow cake batter, while the Oreo Yellow Cake Batter Master Shake takes the same and mixes in Oreo cookie pieces. Both come finished with whipped topping and a maraschino cherry.
As with the rest of the chain's shake offerings, you can get the new, limited-time shakes for half-price after 8 PM all summer long at participating locations.
