Put the coconut oil into a large baking tray

Turn the oven on to 180 degrees/160 fan/gas 4 and place the baking tray and coconut oil inside while it heats up (to melt the oil)

Meanwhile mix together the nuts, seeds and coconut flakes

Carefully remove the tray from the oven and mix the nut and seed mixture around the tray, coating it in coconut oil

Place back in the oven for 5 minutes

Meanwhile peel and chop the banana, then mash well with a fork until smooth

Remove the nut mixture from the oven and stir the mashed banana in well

Replace in the oven for 10 more minutes before stirring again

Bake for a final 5 - 10 minutes until the mixture is crisp and dry

Finally stir in the ground cinnamon and ginger before allowing to cool completely and storing in an airtight container
