I just made CI's molasses cookies (from NBR) yesterday and think they would be great on a dessert table. It's funny that kids just
gobble these up. I thought the strong taste would be offputting, but I've yet to meet a kid that doesn't like them. Not that that matters for your party though.
I also agree a fruit based dessert might be nice, even a fruit salad that could be made a day or two early.
