Grate the carrots and set aside.
Preheat your oven to 180°C (350°F) and line a loaf tin with parchment paper or use a silicone mould.
In a large bowl, mash the bananas with a fork. Add the cinnamon, oil, cocoa powder, honey and egg. Stir until smooth and well combined.
In another bowl, mix together the oats, baking powder and flour.
Add the dry mixture to the banana mixture and stir until fully combined.
Fold in the grated carrots, sultanas and chopped dates.
Tip the mixture into he prepared loaf tin.
Bake for about 60 minutes, or until a skewer inserted into the centre comes out clean.
Let it cool in the tin for 10 minutes, then transfer to a wire rack to cool completely.
Dust with icing sugar or spread cream cheese glaze on top.
