First, peel the banana, then place it into a blender.
Next, pour in the almond milk, then add the matcha powder, the cinnamon, the vanilla, and the nutmeg.
Then, add the ice cubes, and blend for 30 to 60 seconds, until completely smooth and foamy.
After that, taste it, and if you prefer it sweeter, add a little honey or maple syrup.
Finally, enjoy it right away, ideally freshly made.
If you're making it as an evening drink, it's best to reduce or skip the matcha, since it does contain caffeine. Even so, the vanilla and cinnamon still give the smoothie a pleasant, cozy flavor.
