Jack in the Box celebrated St. Patrick’s Day this year by teaming up with Mint Mobile and co-owner actor Ryan Reynolds for the introduction of the “new” limited-edition Mint Mobile Shake.

While new in name only, the Mint Mobile Shake is basically Jack’s signature Oreo Cookie Mint Shake, which takes the brand’s Classic Oreo Cookie Shake and adds cool mint syrup flavoring. The shake is hand-spun with Oreo cookie crumbles and finished with a whipped topping and classic cherry.

Consumers could find the Mint Mobile Shake at participating Jack in the Box locations nationwide from February through April 2, 2023.
