You'll need to chop and freeze the banana the night before, or if you're like me, keep 1-2 chopped frozen bananas in your freezer.
Slice, pit and scoop out the avocado into a blender.
Add in the frozen banana, blueberries, coconut milk, and cocoa powder, along with about 1/2 of the water.
Turn the blender on pulse and continue pulsing until all is blended together. Add additional water if needed.
Pour into a glass and enjoy!
