I've been using recipes from How It All Vegan to make treats for my son, but I don't like to use brown sugar because he has had problems with his teeth. I have been replacing the regular sugar with Splenda, and I was wondering if there was a good substitute for the brown sugar. It seems to bind the recipe together, like it caramelizes or something. I thought about maybe adding some more oil, but don't want to make the cookies or whatever too unhealthy. Thanks.
