Slideshow: The Serious Eats Guide to Girl Scout Cookies

Thin Mints
Thin Mints
Thin Mints are definitely the most popular member of the Girl Scout Cookie troupe. Their success lies in a combination of flavor and texture—a thin, circular mint cookie is encased in a glossy robe of dark chocolate. The result is an almost refreshing mint-chocolate flavor: the cookie cousin of an After Eight. Thin Mint’s lighter-than-air texture becomes particularly crisp after a short stay in the freezer. During the Girl Scout Cookie high season, Little Brownie (and that’s just one of the two Girl Scout Cookie baking companies) bakes over 4.5 million Thin Mints every day.
Samoas (also known as Caramel deLites)
Samoas (also known as Caramel deLites)
Samoas are the second most popular cookie, yet they couldn’t be more different than their troupe leader, Thin Mints. Rather than refreshing and light, these cookies are delightfully decadent. A ring-shaped vanilla cookie base is covered with a layer of Twix-like caramel, then rolled in shreds of toasted coconut and striped with melted chocolate. Samoas are the Girl Scout Cookie of choice for chewy cookie lovers: the caramel actually has a little viscosity and the cookie bends under your teeth.
Do-Si-Dos (also known as Peanut Butter Sandwiches)
Do-Si-Dos (also known as Peanut Butter Sandwiches)
Do-Si-Do’s are a double whammy of childhood treats: oatmeal cookies and peanut butter sandwiches. The oatmeal cookies are on the sweeter, less rustic side of their breed, but fans of Do-Si-Dos appreciate the cookie's crisp contrast to their soft peanut butter interior. We like to think of them like an intended-to-be-healthy Oreo gone rogue.
Tagalongs (also known as Peanut Butter Patties)
Tagalongs (also known as Peanut Butter Patties)
Peanut butter lovers tend to stake their loyalty between these cookies and Do-Si-Dos. The deciding factor for members of the Tagalong camp is usually chocolate—Tagalongs have a thin dark chocolate shell that covers a layer of soft peanut butter and a crunchy short bread base.
Savannah Smiles
Savannah Smiles
The newest member of the Troupe, Savannah Smiles were introduced to celebrate the 100th anniversary of the Girl Scouts. These half-moon shaped cookies have an extremely crunchy interior with an intense, if artificial, lemon flavor. A dusting of powdered sugar makes them very similar to the discontinued Lemon Cooler cookie.
Dulce de Leches
Dulce de Leches
The Girl Scout Cookie website says that these hard, crunchy cookies scattered with milk caramel chips are “inspired by the classic confections of Latin America.” Perhaps the original version felt more authentic: the cookies initially came with a caramel topping. It was removed because it contained too much trans fat.

Lemonades
Lemonades
Lemonades are essentially just Trefoil cookies with a thin layer of lemon icing that have been stamped in the shape of a flower lemon. They replaced Lemon Coolers, Lemon Chalet Cremes, and Lemon Drops as the de facto lemon cookie of the troupe.

Shout Outs!
Shout Outs!
Shout Outs! are intended to be a Belgian-style caramelized cookie, similar to Biscoff cookies. They have the typical, crunchy texture of most Girl Scout Cookies and a lightly spiced flavor. Shout Outs! responded to a growing demand to cut trans fat in Girl Scout Cookies, and these contain zero grams of trans fat per serving, no artificial colors or preservatives, and no high fructose corn syrup.

Thanks-A-Lots
Thanks-A-Lots
Another twist on Trefoils, these cookies take a shortbread base and coat them with chocolate. Taste-wise, they’re almost identical to the discontinued Animal Treasures. Each cookie has the phrase “Thank You” stamped into its face in English, French, Spanish, Swahili, or Chinese.
