In the blender, pour in the milk. Add the peeled banana and peeled and seeded avocado. Blend on medium speed for 30 to 60 seconds, until the texture is completely smooth.
Notes
A medium banana is about 7 inches long, or it's 1 cup's worth of sliced banana.The ripeness of the banana will alter the taste and sweetness. I prefer this smoothie with a somewhat speckled banana.Best when all ingredients are cold.
