Place the aquafaba in the bowl of your stand mixer and turn it to medium speed for about two minutes, until the AF is frothy.
Next, stream in the sugar slowly with the motor running.
Turn the speed up to high and beat until the aquafaba is fluffy and light.
Add the matcha and fold to incorporate.
Fill your mug up with your favourite non dairy milk (hot or cold, if you're doing it cold, add some ice as well), then top with the matcha foam.
