In a small baking dish mix all ingredients in the first layer and freeze for 15 min. I make this twice and keep the second batch in a container in the fridge, to be added on top as the last layer.
Mix ingredients for the second layer. Add on to the first layer and freeze for 1 hour.
Mix ingredients for the third layer. Add on to the layer and freeze for 1-2 hours.
The last layer is the chocolate first layer that was set aside.
After a couple of hours in the freezer, cut into bars and store in an airtight container in the freezer.
