Anytime you can pack some extra goodness and fibre into a sweet treat, without affecting the taste too much I say hooray! These are Banana Crumb Muffins without the crumb topping, made with wholemeal plain flour. As always, I added some cinnamon to the batter. The wholemeal flour changed the taste and texture of the muffin only very slightly. I used four small-medium overripe bananas.
