Jovial makes pretty good gluten-free fig newtons. I'm not trying to discourage you from baking, just letting you know there is something out there. I like them because they really do taste like "regular" food. I think it's because the fruit filling doesn't change and the dough doesn't have to puff. You may look up their ingredients and see what they use as flour.
I will remember that brand name. Problem is that I have a step-father that puts up fig preserves every year and I am overloaded with them. I have searched for a recipe to use all of the preserves that I have and this is the one I came up with. Just still struggling with trying to bake things I can eat and taste good too.
