One of the many excellent recipes in Mark Bittman’s cooking bible, How to Cook Everything, is an outstanding recipe for banana bread.
The secret (besides a whole stick of butter) is the addition of some coconut to the batter. I have adapted his recipe, using a bit more whole wheat flour and melting the butter rather than creaming it with the sugar. Enjoy!
Note that the 12 servings yield is a joke. In the real world, two to four people can polish this off in no time.
