The doughnuts aren't just garnished with Girl Scout cookies they actually taste like the cookies too:
The Thin Mint doughnut is a chocolate doughnut dipped in warm chocolate with chocolate crunchies placed on top to mimic the Thin Mint crunch. Then it's drizzled with chocolate and a mint glaze, with a thin mint placed on top.
The Samoa doughnut is a traditional doughnut dipped in warm caramel, toasted coconut, and topped with a warm chocolate drizzle. A dollop of Bavarian cream is then used to keep the Samoas in place.
Then there's the Tagalongs doughnut, which is a traditional doughnut dipped in chocolate that's topped with peanut butter and a Tagalong.
