Ingredients

Matcha powder: Ceremonial grade matcha is best, but regular culinary ones work too! Feel free to add more for a stronger matcha flavor.
Hot water: Make sure that it is about 60°C to 80°C (140°F to 175°F) so you won’t burn the matcha.
Oat milk: Use barista oat milk if you’d like to froth the milk (either from brands like Oatly or your local house brands). Otherwise, regular oat milk works great.
Liquid sweetener (optional): To balance the matcha’s flavor.
Ice cubes (optional)

How to Make Oat Milk Matcha Latte

Sift the (ceremonial) matcha powder into a small bowl. Or sift into your serving cup if you are not using a whisk.
Add hot water (not boiling) and whisk in a zig-zag motion for 20-30 seconds, or use a frother for 5-10 seconds until combined.

For a cold version, add ice to the serving cup that contains the matcha, and pour the oat milk over. Stir, add the sweetener if needed, and enjoy your iced matcha latte with oat milk!
For warm matcha, warm the oat milk in the microwave for about 45 seconds. Add the sweetener if desired, then froth until it doubles in volume. Pour over the matcha and enjoy!

Can You Froth Oat Milk Cold?

Yes, oat milk can be frothed cold using a handheld frother or electric frother. However, it is usually harder and won’t get as thick as when it is frothed warm. For the best results, use barista oat milk and not the regular oat milk.

Can You Steam Oat Milk?

Yes, oat milk steams well. For the best results, get barista oat milk. They are way better than regular oat milk.

Top Tips

If the water is too hot, it can burn the matcha, making it taste bitter. Aim for 60 to 80℃ (140 to 175°F)—it’s worth the extra care!
Don’t skip sifting the matcha. You can taste the difference!
Adjust your sweetener. You might not need it, but if you want to balance the bitterness from the matcha, add a bit of liquid sweetener such as agave syrup, maple syrup, or (vegan) honey.
