The Newest Girl Scout Cookie Is Finally Available Girl Scout cookie season is here, and the last flavor has finally been released, the Raspberry Rally. The Raspberry Rally features a thin, crispy, raspberry-infused cookie that's been coated in chocolate and is being called the "sister flavor" to the Thin Mint cookie. From now until February 27, all cookie flavors are only available from a local troop. On February 28, you can order cookies online and have them shipped directly to your home. What is your favorite Girl Scout cookie flavor?
