Preheat the oven to 180°C (350°F) and line a loaf tin with parchment paper.
Add the bananas, eggs, rolled oats, baking soda, and maple syrup to a food processor. Blitz for a few seconds, just until the mixture is smooth and combined.
Pour the batter into the prepared tin. Sprinkle over the chopped chocolate and gently fold it through with a spoon to distribute evenly.
Bake for 35–40 minutes, until set in the centre and lightly golden on top.
Leave to cool in the tin for 20 minutes, then transfer to a wire rack and allow to cool completely before slicing.
Notes
This recipe is naturally sweetened, flourless, and made with wholesome ingredients.
Use very ripe bananas for the best natural sweetness.
Oats make this banana bread flourless and high in fibre.
Swap maple syrup for honey if preferred.
Dark chocolate chunks add flavour, but you can leave them out or swap for chopped nuts.
Store in an airtight container at room temperature for 2–3 days or freeze slices individually.
