Every once in a while I get a hankering for that sweet cinnamon flavor, too. I don't eat a LOT of artificial sweeteners, either. The healthy sugar substitute I use is STEVIA. Use it on anything you want to sweeten, it comes in various forms. I like the plain, concentrated white powder. But you can get it diluted with other stuff so it sprinkles more like sugar, in case you want it for cinnamon toast.
Otherwise, I would bake an apple (for instance) and use the white stevia powder, and cinnamon, maybe a tiny amount of raisens.
One note: most stevia newbies make the mistake of using too much, and don't like it, because that gives a bitter aftertaste. So, just try a TINY amount. For example, on one baked apple, I might sprinkle an amount about HALF the size of a pea...if that. Try it, and you soon get the hang of judgeing how much for what dish.
Here is a good link...you don't need to buy it here, but it has lots of stevia info:
