Add all ingredients into a blender and blend until smooth (about 25 seconds)
Notes
For a nice consistency, you will need to use a powerful blender. We love our Blendtec! This KitchenAid Blender is great too and it comes in so many fun colors.
You can sub plain Greek yogurt for flavors like Vanilla or Strawberry.
I've used both fresh fruit that I've put in the freezer the night before and store-bought frozen fruit. Fresh fruit is a little bit more flavorful, but either will work!
