no recipe, here
, but I used to make one for my daughter when she was little that consisted of mashed banana with vanilla as the cookie "base," so to speak. THen added raisins, other dried fruit and nuts (somehow, without any real sweetener, the nuts seem to make it taste sweeter) and I added oats to that and baked them.
She and her friends didn't like the first few bites, but nibbled on them anyway as they played, and then after a cookie or two they started gobbling them up...they are not sweet-tasting at all, but start to just taste good on their own when your mouth adjusts. I've lost the recipe, but it was something like what I put above.
IF you get onto raw recipe boards, there are many recipes for raw "candies" and "cookies" that are based on date paste and stuff like that...I make these quite a bit now...they are really, really tasty. If I bring them to work, they disappear by this SAD-eating crowd faster than I can possibly keep up...I think they'd be a big hit with kids.
I've gotten some really good ones from here:
