Start by peeling the ripe banana and cutting it into slices. This quick task should take about a minute.

In a blender, combine the sliced banana, matcha powder, your preferred milk, and Greek yogurt. Add ice if using fresh banana.

Blend the mixture on high speed for about 30-45 seconds until creamy and uniform. Check for remaining chunks and blend longer if necessary.

Pour the smoothie into a glass and enjoy immediately for the best freshness and flavor.
