Social media is abuzz with reports that Wendy's will unveil an all-new flavor of Frosty in February incorporating one of the oldest Girl Scout cookies.

Wendy’s is bringing its beloved vanilla Frosty back, and a special new flavor is rumored to be joining the mix. The fast food chain has indicated on its website that “Wendy’s Vanilla Frosty is Back” at all stores in the U.S.. However, the company didn’t specify how long the dessert will be back in stores, or if it has returned permanently.

Rumors have been swirling online about the possibility of a Girl Scouts collaboration with Wendy's for a Thin Mint-flavored Frosty. "The frosty is rumored to be available sometime in February and will use a vanilla base with a thin mint swirl," according to an Instagram post from Snackbetch, a popular page for food news.
