Lightbright:
Key question is why are you avoiding gluten (celiac or something else) in the first place? If it’s not celiac, you may have luck with spelt vs. regular wheat, so it may be worth a try, especially for Challah (to start with, as it has no other ingredients besides water, whole spelt Matzah is even better). Many packaged gluten free treats are loaded with sugar, potato, rice, and other fillers that are not exactly healthy AND are expensive to boot.
Cravings may be legitimate if you are severely restricting carbs and you’re not diabetic, so it may be wise to listen to them, but don’t jump from from the frying pan into the fire. A good test would be to bake stuff yourself, which will limit the amounts and ensure you’re craving it enough to put in the time and effort. (One fairly simple recipe you can find many variations of online using basic ingredients is for “chick-pea chocolate chip cookies”.) Good luck!
