Brownie Batter and Yellow Cake Batter Shakes are Back at Sonic

Sonic brings back the Brownie Batter Shake and Yellow Cake Shake for a limited time, while supplies last. Both shakes are available early now through March 21, 2022 for Sonic app users. A wider, nationwide release begins on March 28, 2022.

Sonic's Brownie Batter Shake features vanilla ice cream blended with chocolate brownie batter and brownie pieces, while their Yellow Cake Batter Shake takes the same vanilla ice cream but blends it with yellow cake batter instead. Both shakes are finished with whipped topping and a maraschino cherry.
