Using a frozen banana helps to naturally thicken the smoothie and gives it a cold, creamy texture without needing extra ice. If you only have a fresh banana on hand, you can toss in a few ice cubes to achieve a similar chilled effect.
The nutrition details provided are based on the smoothie made with plain Greek yogurt and whole milk. Using different types of milk or yogurt, such as low-fat, non-dairy, or flavored options, will slightly change the nutritional values.
