Oatmeal Heart Cut-Out Cookies

I created this recipe without xanthan gum and it worked beautifully. The binding action comes from the arrowroot and the oats. I think there are many possibilities to modify this recipe. For example, adding one tablespoon of ground cinnamon to the dough would be delicious! Or dust each heart with cinnamon before baking. For the chocolate lovers out there, the cookies can be dipped in a chocolate glaze after baking. I like them better plain, but you decide.
