First, add all the smoothie ingredients into your blender. For most blenders, start with the frozen banana and avocado at on the bottom, as that is the hardest for the blender to blend.
Add the milk into the blender last, then blend until smooth. You will probably need a blender tamper to stir everything until combined. In this recipe, we use minimal liquid to make sure our smoothie is as thick as possible. It may take patience and maneuvering to get your smoothie smooth. Sometimes I have to pause and let all my ingredients thaw slightly before blending again. See notes for details.*
Once your smoothie is done, top it with your favorite toppings of your choice! Enjoy immediatley!
