This banana bread recipe calls for plain yogurt which I think really helps to keep the bread moist. As I am sure that I have mentioned (one more than one occasion) I do not like nuts, so I used dried cranberries instead.
This is by far and away the best banana bread I have ever eaten! Peter really likes it to, but says until I add the walnuts in it will not be the best he has ever had....maybe next time! ;-)
