Finely grind the oat flakes in a blender or similar (e.g. Moulinette / Thermomix / ) and mix with the coconut flakes, chocolate flakes and the sliced (and slightly chopped) almonds.
Fill the oatmeal mix into a storage container. Fill the coconut chips separately as a topping.
To prepare, stir 50 g of the mixture into 200 ml of milk (alternatively coconut or almond milk) and place in the microwave for about three minutes. Stir once in between, if necessary. Then stir again well and let it steep for a minute.
