I came up with this recipe to use up some extra bananas and yogurt, but since I live alone, eating a whole banana bread to myself is... well... pure gluttony. So, to my great pleasure, there is no willpower needed here! I am very proud of how it came out. It is very moist and the buckwheat gives it a nice flavour. If you are used to regular store-bought over-sweetened cakes, I recommend you increase the amount of sugar in the recipe or, you can use these tricks: use over-ripened bananas (they are sweeter), use sweetened applesauce and/or vanilla yogurt instead of plain.
