Banana and chocolate is a well known combination, but we have used Nutella for added flavour, which is so much better! The plain yoghurt used in the batter, along with the mashed bananas, means that this sponge is lovely and moist. With an additional Nutella drip and scattered hazelnuts top, this recipe makes for the perfect afternoon snack or tea-time treat.
