I just made chocolate chip cinnamon cookies using tapioca flour in place of normal flour (I cannot have wheat/gluten). They taste really good and very much like cookies, but they have the weirdest texture. They are very sticky, almost glue-y in fact. I just thought I would put this out there in case anyone was thinking about using tapioca flour to bake with. It's even weirder because the bag specifically said that the flour was good for baking. It lied.
