01 - Sift the matcha powder into a mug to remove clumps and ensure smooth texture.
02 - Add the hot water to the sifted matcha. Whisk vigorously with a bamboo whisk or small regular whisk until completely smooth and frothy.
03 - Heat the oat milk in a small saucepan over medium heat until steaming but not boiling. Alternatively, microwave in a microwave-safe container for 45–60 seconds.
04 - Froth the heated oat milk using a milk frother or whisk until foamy and doubled in volume.
05 - Pour the frothed oat milk into the mug with matcha, holding back the foam with a spoon. Spoon the foam on top of the latte.
06 - Stir in maple syrup or sweetener if desired. Serve immediately, optionally garnished with a light sprinkle of matcha powder on top.
