The very idea of a sugarless cookie makes me wince a bit, I admit. The problem is, I wanted to send cookies to my SO's grandparents this year as part of their present, but they're inexplicably hooked on Splenda. I'm not sure why, as neither of them have had problems with diabetes, but they sub it for sugar almost 100% of the time. They're wonderful people, so I know they'll be appreciate any gift, but I think they'd enjoy cookies more if they were sugar free. I've never cooked with sugar substitutes before though, so I have no idea which recipes are good and which would be a waste of time. Does anyone have any good recipes or tips for sugar-free cookies tucked up their sleeve?
