Combine the rolled oats, apple juice and cinnamon powder together in a glass bowl, cover and place in the fridge overnight to marinate.

In a medium sized saucepan over a low heat, melt the coconut butter and combine it with the honey.

Remove the saucepan from the heat and add the marinated oats. The oats will have solidified whilst marinating so will need added in spoon fulls and then stirred in. Combine well to remove any lumps.

Empty the oats mixture into the lined baking tin and flatten it out by pressing down with your fingers to get it into the corners.

Pop back into the fridge for a couple of hours to allow the oats to cool and harden.

Remove, cut into 8 bars and keep in the fridge until required.
