I found this recipe on a cookie website and tried it using Bob's Red Mill Gluten Free All Purpose Baking Flour. They turned out great and tasted like normal cookies! It took me a few batches to get the browning right but I found that by cooking them slightly longer and having them be a little more browned they were easier to remove from the baking sheet and not have the cookies fall apart. I added the lemon extract to the batter because I had it on hand and it made for just a slight hint of lemon and they tasted great, but that can be optional. I also added some sprinkles for some color and my kids loved them. I also used a round pizza pan to bake the cookies in and they turned out better than a rectangular sheet.
