With Girl Scout Cookie season in full swing, Wendy’s today announced the return of its fan-favorite Thin Mints Frosty Swirl, along with the all-new Thin Mints Frosty Fusion, available at participating locations starting February 17, 2026.
Here’s a closer look at the seasonal Girl Scout Cookie-inspired Frosty treats:
- New Thin Mints Frosty Fusion: This new menu item mixes Wendy’s Vanilla Frosty with a mint-flavored cookie crumble sauce and pieces of Girl Scout Thin Mints cookies. The result is a smooth Frosty with bits of chocolate and mint throughout.
- Thin Mints Frosty Swirl: The returning Frosty pairs Wendy’s Vanilla Frosty with a mint cookie crumble sauce, swirled in and layered on top, inspired by the flavor of Girl Scout Thin Mints.
Both treats combine Thin Mints–inspired flavors with Wendy’s signature Frosty and can also be ordered using a Chocolate Frosty base instead of vanilla.
Prices may vary, but at my local Wendy’s, the Girl Scout Thin Mints Frosty Fusion starts at $4.19, while the Girl Scout Thin Mints Frosty Swirl starts at $2.99.
You can find both new and returning Thin Mints Frosty desserts at participating Wendy’s locations nationwide for a limited time.
