Prep the ingredients - Peel and cube the taro root and sweet potato. Measure out the ice cubes, coconut milk, maple syrup, and vanilla extract. Place all of the ingredients in separate bowls or containers for easy access while blending. - Taro root can be sticky and can cause itchiness when it comes into contact with skin. Wear gloves or coat your hands with oil to prevent this. Also, make sure to use a sharp knife to cut the root vegetables as they can be tough to cut.
Blend the ingredients - Add the cubed taro root, sweet potato, coconut milk, maple syrup, vanilla extract, and ice cubes to the blender. Blend on high for 1-2 minutes until smooth and creamy. - Start blending on a low speed and gradually increase to high speed to ensure that all the ingredients are well combined. Do not overblend, as this will cause the smoothie to become too thin. If the mixture is too thick, add a splash of non-dairy milk to thin it out.
Serve and enjoy - Divide the smoothie between two glasses and serve immediately. - Garnish with a sprinkle of cinnamon or chopped nuts for an extra flavor boost and added texture. If you have any leftover smoothie, pour it into a popsicle mold and freeze for a tasty frozen treat!
