Hi. I also wanted a healthier cake, particularly for my son's first Birthday, as we weren't giving him much sugar or desserts at that point. I found a good recipe on this wholesome baby food website that we all liked: http://www.wholesomebabyfood.com/tipFirstBDay.htm
I believe it was the applesauce spice cake.
This year (for his 2nd B-day) I made a chocolate banana bread recipe (which tastes close enough to cake) with no icing & it also was very good & he loved it. Here's the recipe for that:http://www.cooks.com/rec/doc/0,174,145188-234193,00.html
but I left out the nuts & added chocolate chips.
