Start by gathering all your ingredients and measuring them properly. Make sure the banana and blueberries are frozen so the smoothie becomes thick and cold. Frozen fruit also helps maintain nutrients and gives a creamy texture.
Place the milk, frozen blueberries, frozen banana, matcha powder, vanilla extract, and ice cubes into a blender. Adding liquid first helps the blades move more easily and ensures smoother blending.
Blend everything together until the mixture becomes completely smooth and frothy. If the smoothie feels too thick, add a small amount of extra milk and blend again until you reach your desired consistency.
Taste the smoothie after blending. If you prefer it sweeter, you can add a small drizzle of honey or maple syrup and blend briefly again.
Pour the smoothie into glasses and serve right away. The cold texture and fresh flavor are best enjoyed immediately after blending.
