*If you can’t get on board with the greens-in-smoothies thing, you can opt for green food coloring or just drink a white peppermint shake (which is just as delicious). Or add a pinch of spirulina!Feel free to use your favorite milk of choice. Canned coconut milk will give it a rich milkshake-like taste, but I also really love the lighter results of using cashewmilk or almond milk. Make sure the banana you use is at least somewhat brown so you don't get that unripe earthy banana flavor in your mint chocolate shake. To make the shake: Blend all ingredients in a blender until completely smooth. You can add the chocolate chips either before or after blending. Be sure to use pure peppermint extract, not imitation.View Nutrition Facts
