Start by making the vegan egg in a jar with a lid so you can give it a nice shake. This will reduce the waiting time for the seeds to expand to only a few minutes.
Take a large bowl and mix the bananas and dates. Add the oats, baking powder, plant cream, almond flour, buckwheat. Add the vegan egg if the chia seeds have turned into a gel otherwise wait for a few more minutes.
Put the oven on 175ºC/347.00ºF. Give the dough a nice stir and add into a bread pan coated with a baking sheet. Bake the banan bread for 15-20 minutes. Serve with a nice nut butter.
