In a large bowl, add together dry ingredients and mix.
In a separate bowl, add together all wet ingredients, mash the bananas with a fork, and mix.
In the bowl with the wet ingredients, add the dry mix and stir for a few seconds with a wooden spoon until roughly incorporated (do not over-mix).
Pour into a baking form (we use a 31x13cm / 12x5in ) with a sheet of baking paper inside.
Optional: you can add some banana slices on top of the bread. In this case sprinkle the banana slices with sugar to facilitate caramelisation in the oven.
Bake for 50 mins at 180 °C or 360˚F. Let cool down before serving.
