Remove the half frozen banana from the freezer and break or cut it into smaller pieces. Then place the banana pieces in the blender pitcher.
Add the scoop of cacao protein powder, the tablespoon of raw cacao, the almond butter and the almond milk to the banana. Turn on the blender and mix all ingredients on high speed until smooth and thick with no large pieces visible.
Turn off the machine and scrape down the sides with a spatula to incorporate everything. Pour the thick smoothie into a large bowl.
Distribute the tablespoon of cacao nibs and the tablespoon of grain-free granola evenly over the top of the mixture. Serve immediately so the smoothie bowl stays thick and cold.
