Oh my gosh! This sounds so good. Someone just posted a link to a recipe for Girl Scout Cookie Thin Mint Brownies on a message board I frequent. They look delicious. Thin Mints are my absolute favorite Girl Scout cookie, so I'm going to have to try this one out.
The recipe is on Little Brownie Bakers' website. They have been making Girl Scout cookies for 25 years. Check out the site. There are lots more great recipes to be found there. Yum!
