I found this recipe when I was working with a community kitchen which was also a little vegan paradise for students. This bread will convert non-vegans in one mouthful. I did tweak it to decrease the amount of sugar, feel free to add a little more if your bananas are a little green.
Tip 1 : if you're planning a banana bread but your bananas are not ripe yet, pop them in a paper bag for 2-3 days and they will be ready.
Tip 2 : double the quantities and freeze the breads, they keep for a good 2-3 months.
