Since 1917, the Girl Scouts of the United States of America have been selling baked goods to raise funds to support local community service projects, maintain Girl Scout camps, develop programs and provide financial support to girls in need.

Last year, in the Washington, DC, area alone, more than 4.5 million boxes of cookies were sold.

While scouts still sell cookies door-to-door, the Girl Scouts have gone high-tech in the last few years, offering the "Cookie Club" website—which allows scouts to sell cookies via email—and launching the Girl Scout Cookie Locator app so that one is never more than a few clicks away from one's favorite cookies:

• Thin Mints
• Samoas
• Trefoils
• Do-Si-Dos
• Tagalongs
• Savannah Smiles (lemon flavored)
• Dulce de Leche
• Thank You Berry Munch

So, we want to know, what is your favorite Girl Scout Cookie, and why? Vote in our poll or tell us in comments.
