Peel the banana and ideally freeze it beforehand. Measure your non-dairy milk, matcha powder, and sweetener. This prep ensures smooth blending without lumps.
Add banana, milk, matcha, maple syrup, and ice cubes to your blender. Blend on high until creamy and smooth, scraping down the sides if needed.
Taste your smoothie and add more syrup if you like it sweeter. You can also add extra milk to thin it out if needed.
Pour the smoothie into your favorite glass. Top with a sprinkle of matcha powder or sliced banana for a visually appealing touch.
