Put all ingredients in order in a magic bullet cup or blender. If using a blender, this recipe can be doubled. I didn't have a frozen banana (easy to do, peel, cut into chunks and pop in a ziploc into your freezer) so I added a ripe banana and a few ice cubes. Blend until everything is mixed. The cacao nibs won't be completely crushed and add a nice crunch to your smoothie.
