In a small bowl, whisk together the matcha powder and hot water with bamboo whisk until the matcha is fully dissolved and there are no lumps.
Fill a glass with ice, then pour the milk over the ice. This will help keep the latte cold and refreshing. You can use a milk frother to get a frothy matcha latte.
Add the sweetener to the milk and mix it until it dissolves.
Pour the matcha mixture into the milk and stir well until everything is combined.
Enjoy your iced matcha latte immediately.
Notes
Start with good quality matcha powder. Look for a high-quality ceremonial-grade matcha powder, which will have a vibrant green color and a smooth, slightly sweet taste.
Always use a whisk or blender to mix the matcha powder with a small amount of hot water before adding the cold milk.
