"sugar-free" muffins and cookies?

[supercarrot]

hey all. i was wondering if any of you had any "sugar-free" recipes for cookies and muffins. any flavor will do. list whatever you've had successes with. i'm open to anything. i need to expand my horizons.

maple, agave, stevia are all fair game. i was also going to pick up a bag of date sugar and experiment with that.
(i've never been a fan of brown rice syrup, but if you have a recipe where the flavor doesn't come through too much, lay it on me.)

thanks so much!
