Preheat the oven to 180c/350f.
Add the oats to a blender and blend to a flour like consistency.
Add all of the ingredients to a blender and blend until combined (don’t overblend as it can lead to a tough batter, some banana chunks are fine)
Grease or line a loaf tin (9”x5”) then pour the batter in (optional to top with an extra banana for decoration) and cook for 50 – 60 minutes (do the toothpick test or just by eye).
Cool in the tin for 5 mins before removing and leaving to cool on an airing rack for one hour before cutting in to ~8 slices.
Serve however you like (we love it warm with some coconut oil or almond butter spread on it)
Store on the bench for 2 days, fridge for 5, or freeze in slices for 2 months
