This is a brand-new Frosty flavor, and it’s a seasonal collaboration between Wendy’s and the Girl Scouts. I decided to try one even though I think Thin Mints are highly overra

Both the chocolate and vanilla variations have the same swirl of Thin Mint flavor, in "a rich, minty cookie crumble sauce."

The Thin Mint Frosty incorporates the flavor of the Thin Mint Girl Scout cookie into a Wendy's chocolate or vanilla Frosty. The Frosty has a minty-chocolatey, crumbly, cookie butter texture swirl around the cup. The presentation will be similar to what Wendy's did with the SpongeBob Pineapple Under the Sea Frosty.
