Preheat the oven to 200 C / Gas 6. Grease and line a 450g loaf tin with baking parchment.
In a mixing bowl, combine the flour, baking powder, salt, bicarb and cinnamon and mix. Then add the chopped dates.
In a separate bowl combine the coconut oil, vanilla extract and bananas and mash together with the demerara sugar.
Combine the wet and dry ingredients together in one bowl and mix together till it reaches the consistency of a dough. If still a bit dry you can add a few teaspoons of water. Mix well then transfer to the prepared loaf tin.
Bake in the preheated oven for 30 to 35 minutes or until a skewer inserted into the centre comes out clean. It should also have a nice golden colour to it and be firm to the touch. Remove from the oven and allow to cool. Drizzle with a little icing sugar mixed with water if desired. Slice and serve.
