Instructions
-
1
Sift the matcha powder into a small bowl or mug to remove any clumps. This step is important for a smooth, lump-free latte.
-
2
Add 2 tablespoons of hot water (not boiling—around 175°F is ideal) to the matcha powder. Using a bamboo whisk or a small regular whisk, whisk vigorously in a zigzag or "M" motion for about 30 seconds until the matcha is fully dissolved and slightly frothy on top.
-
3
Stir in your sweetener of choice while the matcha mixture is still warm. Maple syrup, honey, or simple syrup all work beautifully here. Start with 1 teaspoon and adjust to your preference—matcha has a naturally earthy, slightly bitter flavor that some people love unsweetened.
-
4
Fill your glass with ice cubes. Pour the cold oat milk over the ice, leaving about an inch of space at the top.
-
5
Slowly pour the prepared matcha mixture over the oat milk and ice. For a beautiful layered effect, pour it gently over the back of a spoon. Or, give it a good stir to mix everything together. Add a pinch of vanilla extract if you want an extra layer of flavor, then enjoy immediately!
Don't use boiling water to dissolve your matcha—it can make it taste bitter and destroy some of the delicate flavor compounds. Let your kettle cool for about 2 minutes after boiling, or aim for water around 175°F (80°C). The result is a sweeter, smoother matcha with no bitterness.
Recipe Variations
Strawberry Matcha
Add 2 tablespoons of strawberry syrup or muddle fresh strawberries at the bottom of your glass before adding ice and milk. Beautiful pink-and-green layers!
Brown Sugar Matcha
Swap the maple syrup for brown sugar syrup (equal parts brown sugar and hot water, dissolved). Adds a caramel-like richness that pairs wonderfully with matcha.
Coconut Matcha
Replace the oat milk with coconut milk for a tropical twist. Add a splash of coconut cream on top for extra indulgence.
Toasted Almond Matcha
Use almond milk instead of oat milk and add ¼ teaspoon of almond extract. Top with a sprinkle of toasted almond slivers for texture.
White Chocolate Matcha
Add 1 tablespoon of white chocolate sauce when whisking the matcha with hot water. Creates a creamy, dessert-like drink that's still refreshing over ice.
Citrus Matcha Refresher
Add a squeeze of fresh lemon or orange juice before pouring the oat milk. The citrus brightens the earthy matcha in an unexpected, refreshing way.
Storage & Make-Ahead Tips
🧊 Matcha Concentrate
You can prepare the whisked matcha mixture (without ice and milk) up to 24 hours ahead. Store it in an airtight container in the fridge. Just shake well before using, as the matcha may settle slightly. This is perfect for busy mornings when you want to grab your drink and go.
🧃 Complete Drink Storage
Once mixed with ice and milk, this drink is best enjoyed immediately. If you need to store a complete drink, keep it refrigerated for up to 8 hours in a sealed container, but know that the ice will melt and dilute the flavor. Give it a good shake before drinking.
🧊 Matcha Ice Cubes
Here's a brilliant trick: make extra matcha mixture and freeze it in ice cube trays. Use these matcha ice cubes instead of regular ice in your latte, so as they melt, they won't dilute your drink—they'll actually make it stronger! These keep for up to 3 months in the freezer.
📦 Matcha Powder Storage
Keep your matcha powder fresh by storing it in an airtight container in a cool, dark place—or even better, in the fridge or freezer. Matcha is delicate and can lose its vibrant color and flavor when exposed to light, heat, and air. Properly stored matcha stays fresh for 6-12 months.
For an on-the-go version, prepare your matcha concentrate the night before and store it in a small jar or bottle. In the morning, just pour it into your tumbler with ice and cold oat milk, give it a shake, and you're ready to go in under 30 seconds.
Matcha 101: What You Need to Know
If you're new to matcha, here's the quick rundown that'll help you make the best iced latte possible.
Types of Matcha
There are two main grades: ceremonial grade (bright green, smooth, slightly sweet—perfect for lattes) and culinary grade (more bitter, darker—better for baking). For this recipe, ceremonial grade gives you the best flavor, but culinary grade works if you're adding sweetener.
Why Whisk It?
Unlike coffee or tea, matcha is a fine powder that doesn't dissolve easily—it needs to be whisked to break up clumps and create a smooth, frothy consistency. A bamboo whisk (called a chasen) is traditional and works beautifully, but a regular small whisk, milk frother, or even a sealed jar you shake vigorously will do the job.
Health Benefits
Matcha is loaded with antioxidants (especially catechins), provides calm, focused energy thanks to L-theanine, and may support metabolism and heart health. One cup contains about 70mg of caffeine—less than coffee, but with a smoother, more sustained energy boost and no crash.

Tools & Equipment
You don't need any fancy equipment to make this recipe, but here are the tools that make the process easier:
Whisk (bamboo or regular)
A bamboo matcha whisk (chasen) is traditional and works beautifully, but a small regular whisk works just fine. Even a milk frother or a jar with a tight lid for shaking will do the job.
Fine-mesh sieve
For sifting the matcha powder to remove clumps. This step makes a huge difference in getting a smooth, lump-free latte.
Large glass or tumbler
A 16-20 oz glass works perfectly. For on-the-go, use an insulated tumbler to keep your drink cold for hours without dilution from melting ice.
Thermometer (optional)
If you want to be precise about water temperature, a simple kitchen thermometer helps you hit that sweet spot of 175°F for the smoothest matcha flavor.
