There is a very good book called Simply Gluten Free Desserts by Carol Kicinski. It hits all the notes you’d expect in a GF desserts recipe book, such as pie crust, cookies, cakes, and the likes. This blend makes the best cookies… amongst other things!

Also… go buy Carol’s book. So many good recipes.
