Wendy’s teased that they are leveling up their Frostys, and now we know how. Frosty Swirls will be available on their app in a soft launch today. The flavors are Strawberry, Caramel, and Brownie Batter flavors, which you can add to Chocolate or Vanilla Frostys. They’re fully available on Tuesday. Joining the fun later this spring will be Frosty Fusions. The flavors for the Fusions are Caramel Crunch flavor, Pop-Tarts Strawberry Frosty Fusion and Oreo Brownie Batter Frosty Fusion. Wendy’s reminds you to use a spoon so you don’t miss a single drop.
