Wendy's is bringing back its wildly popular Thin Mints Frosty for a limited time, and this year it's offering an even more indulgent Thin Mints Frosty Fusion option packed with real crushed Thin Mints cookies. The chain is also hosting local Girl Scout troops at participating locations during cookie season, making it easy for fans to grab a box of Thin Mints and a matching Frosty in one stop.

Why it matters

The Thin Mints Frosty was a viral hit last year, with fans lining up to try the mint-chocolate mashup. Wendy's is doubling down on the popular treat by adding an even more decadent Frosty Fusion option, catering to the legions of Thin Mints devotees who already know the joy of stashing the cookies in the freezer for that perfect icy, snappy bite.

The details

The Thin Mints Frosty is available in both chocolate and vanilla bases, with a luscious crumbled cookie sauce that delivers the icy, chocolatey snap Thin Mints fans love. The new Thin Mints Frosty Fusion takes it a step further, folding real crushed Thin Mints straight into the Frosty alongside the mint-chocolate sauce. The result is an even more indulgent treat with more crunch and more of that cool, chocolate-mint magic in every spoonful.

  • The Thin Mints Frosty is available starting February 16, 2026.
  • Wendy's will host local Girl Scout troops at participating locations throughout cookie season starting February 1, 2026.
