I'm making a whole wheat pastry flour, sugar free shortbread cookie for a friend. A small portion of the cookie is supposed to be dipped in chocolate both for asthetics and flavor . Unfortunately I can not find sugar free dipping chocolate or bars in any of my local stores. I do have some unsweeted bakers chocolate, but am wondering if that would be too bitter. What do you think? Does anyone have a suggestion on how I can handle this?
