This recipe is fantastic! I did make the following changes as others recommended: 1 tsp baking powder, split the sugar 1/2 cup white and 1/2 cup brown, more like 1.25-1.5 cups banana.
I also had some extra finely chopped pecans (maybe 1/2 cup?) around from a different baking project and threw them in the batter...it added a little more body to the dough and gave it a bit of a savory balance to the sugar. My husband doesn't like banana-flavored anything, but loves these! Definitely a keeper!
