Girl Scout Cookies have been a part of the scouting program for decades. While the tradition started in the early 1900s as a bake sale to raise funds for a troop, the idea quickly caught on, with the organization eventually standardizing the production of these treats.

One of the most popular Girl Scout cookie flavors is getting made into Wendy’s signature desserts. Wendy’s is partnering with Girl Scouts of the USA for its new Thin Mints Frosty.
