Everyone loves Wendy’s popular frozen treat — the Frosty. Even more so, now that the fast-food chain has introduced seasonal flavors on the menu.
And, this spring, the flavor of the season is Thin Mints. The limited-time flavor combines the Classic Chocolate or Vanilla Frosty, swirled and topped with a rich, minty cookie crumble sauce — inspired by the flavor of Girl Scout Thin Mints.
