Peel your banana and freeze it overnight. Frozen banana makes the smoothie thick and creamy — fresh banana makes it thin and watery.
Add milk first, then Greek yogurt, frozen banana, and protein powder on top.
Blend on high for 45–60 seconds until completely smooth. If it’s too thick, add a splash more milk. If it’s too thin, add a few ice cubes and blend again for 15 seconds.
Tilt the blender — it should move slowly, like a thick milkshake. If it pours out instantly like juice, it’s too thin. Add more banana or yogurt next time.
Pour into a glass and drink right away. Smoothies separate and lose texture within 20–30 minutes. This is not a meal prep item — make it fresh, drink it fresh.
