Add all of the smoothie ingredients to a high-powered blender and blend until smooth.
Taste the smoothie for flavor and texture. For colder, thicker smoothies, add 3 to 5 large ice cubes and blend until incorporated.
You can add more orange juice (or milk of choice) for a thinner consistency.
Pour smoothie into one large glass or two medium-sized glasses and enjoy!
If you don’t finish the smoothie, store it in an airtight jar for up to 24 hours.
Smoothies are best when consumed fresh, but saving a smoothie is acceptable for later use.
