Samoas were my favorite type of girl-scout cookie before going gluten-free. Now I haven't had one in over two years. When I saw a recipe for homemade Samoas, I knew I had to make a batch that was gluten-free. These take a while to make and are completely terrible for you but it's so worth it! * For the flour mix, I used Bette Hagman's Mix with great success: 2 parts garfava flour, 1 part sorghum flour, 3 parts cornstarch and 3 parts tapioca flour. Feel free to experiment with your own shortbread cookie mix though.
