Girl Scout cookies were first sold by troops in the '20s and '30s for 25 to 30 cents per dozen. As of 2015, Girl Scout cookies now range from $4 to $5, depending on the region.
In 1922, American Girl magazine published a simple sugar-cookie recipe, so Girl Scout troops could make and sell cookies to fund their activities. The Girl Scout cookie has since evolved and grown. In 1951, the Girl Scouts expanded sales to include Peanut Butter, Shortbread and Chocolate Mint, which were later renamed Thin Mints. By 1978, Girl Scouts were sold in uniformed boxes and only made by four licensed bakers. By the 21st century, Girl Scouts had eight varieties of cookies and were made by only two bakers.
As of 2015, Girl Scout cookies are available in 12 selections. In 2015, Girl Scouts raised prices for the first time in a decade, but according to Time, Girl Scout cookies are still being sold below their value of $5.84. Girl Scout cookies can be purchased online as of 2015 for the first time in nearly 100 years of production. All proceeds from cookie sales benefit local Girl Scout councils to fund their troop activities, travel and program supplies.
