Prep your fruit. If using fresh blueberries and banana, peel the banana and break it into chunks. Frozen fruit works great and makes a thicker smoothie.
Add liquids first. Pour the milk into the blender. This helps the blades catch everything and blend smoothly.
Layer in the creamy base. Add the Greek yogurt on top of the milk.
Add the fruit. Toss in the banana and blueberries.
If using frozen fruit, you may not need ice.
Flavor it up. Add honey or maple syrup if your fruit isn’t very sweet, plus vanilla and a pinch of cinnamon if you like.
Blend until smooth. Start on low, then move to high for 30–45 seconds. Add more milk a splash at a time if it’s too thick.
Adjust and serve. Taste and adjust sweetness or thickness. Pour into a glass and serve right away.
