As of 2015, there are 12 varieties of Girl Scout cookies. The oldest, and most widely distributed varieties are Peanut Butter Sandwich, Shortbread and Thin Mints. These three varieties have been in production since 1951, according to the official Girl Scouts website
The Girl Scouts organization contracts two different bakers to produce all of their cookies. Each baker is required to make Peanut Butter Sandwich, Shortbread and Thin Mints, as well five more optional varieties from the 12 possible cookie recipes. These possible cookies include Savannah Smiles, Thanks-A-Lot, Toffee Tastic, Lemonades and Rah-Rah Raisins.
ABC Bakers and Little Brownie Bakers produce all of the girl scout cookies sold in the United States. Girl Scouts provides the nutritional information and ingredients for each cookie online. There may be slight differences in the ingredients and nutrition for cookies of the same type that have been produced by different bakeries. With each bakery producing only eight of the 12 recipes, some cookie varieties may not be available in certain regions. For example, Cranberry Citrus Crisps are produced only by ABC Bakers, while Savannah Smiles are produced only by Little Brownies. Luckily, Girl Scouts allows users to enter their zip code to find out which cookies are available in their region.
