Put all the ingredients in the blender. Chop the banana into pieces if it does not fit whole
Blend until smooth
Serve your chocolate banana smoothie and enjoy!
Notes
You can use a food processor instead of a blender. Blender is a much better option since it works better making your work easier
If you want a vegan smoothie you can substitute the honey with agave.
Using frozen bananas is much better since it gives you a thick consistency. You can however use ice cubes when working with unfrozen bananas.
