In a bowl, combine the chia seeds, kefir, plant-based milk, maple syrup, Greek yoghurt, and white miso paste. Mix well until everything is thoroughly combined.
Slice the bananas and gently fold them into the mixture.
Cover the bowl and refrigerate for at least a few hours or overnight to allow the chia seeds to expand and the pudding to thicken.
Before serving, give the pudding a good stir and dust the top with raw cacao powder.
