Notes
Peanut Butter: Feel free to use almond butter or sun butter (if nut-free).
Freezing: You can freeze smoothies for up to 3 months. I like to freeze them in ice trays and store them in freezer-safe bags as “cubes.” When you are ready to enjoy, simply add to a glass and let thaw in the fridge for a few hours or overnight. You can also blend the smoothie ice cubes for a quick thaw.
