Matcha Cold Foam: How to Make It at Home (and Top an Iced Matcha Latte)
Matcha isn’t just for hot tea anymore. You’ll find it in iced lattes, smoothies and all sorts of café drinks, but one of the nicest ways to enjoy it is with a layer of creamy matcha cold foam.
The foam sits atop a cold drink, adding a smooth texture and a gentle green tea flavour with every sip. It looks impressive, too, especially when served over an iced matcha latte in a clear glass.
Making matcha cold foam at home is surprisingly straightforward. This matcha cold foam recipe uses a few simple ingredients and a cream whipper to create a light, creamy topping without spending ages whisking or frothing milk.

What Is Matcha Cold Foam?
Matcha cold foam is a chilled, aerated mixture of matcha powder, milk, cream and sweetener. It’s designed to sit on top of iced drinks rather than blend completely into them.
Unlike the warm, steamed milk used in a traditional latte, cold foam is prepared without heating the finished mixture. The cream provides enough richness to help the foam hold its shape, while the milk keeps it lighter and easier to dispense.
This particular recipe produces a richer matcha cream topping than traditional milk-only cold foam. The extra cream gives it more body, making it particularly suitable for dispensing from a cream whipper.
A regular iced matcha latte usually combines matcha, milk and ice in one drink. Adding matcha cold foam creates a separate creamy layer, giving you a richer texture and a more pronounced matcha flavour as you sip.
Ingredients for Matcha Cold Foam
This recipe makes approximately four generous foam toppings, depending on how much you dispense per drink.
Preparation time: 10 minutes
For the Matcha Cold Foam
- 150 ml cold thickened cream
- 100 ml cold full-cream milk
- 2 teaspoons matcha powder, sifted
- 2 tablespoons icing sugar or another fully dissolvable sweetener
- 1 tablespoon warm water, for mixing the matcha
- ½ teaspoon vanilla extract (optional)
For Two Iced Matcha Lattes
- 2 teaspoons matcha powder, sifted
- 60 ml warm water, approximately 70–80°C
- 400 ml cold milk
- 1–2 teaspoons honey or sugar syrup, to taste
- Ice cubes
You’ll also need a fine-mesh sieve, a small whisk, a mixing jug, two tall glasses and a cream whipper with a compatible food-grade cream charger.
How to Make Matcha Cold Foam in a Cream Whipper
The key to smooth foam is preparing the matcha properly before it goes anywhere near the whipper. Dry matcha powder tends to form small clumps, which can affect the texture and potentially block the dispensing nozzle.
Follow these five steps to make a creamy matcha foam topping for your favourite iced drinks.
Step 1: Sift and Mix the Matcha
Sift two teaspoons of matcha powder into a small bowl. Add one tablespoon of warm water and whisk until you have a smooth, lump-free paste.
You only need enough water to disperse the powder. Adding too much can dilute the mixture and make the finished foam thinner.
Step 2: Combine the Cream and Milk
Pour the cold thickened cream and full-cream milk into a mixing jug. Add the icing sugar, vanilla extract and prepared matcha paste.
Stir gently until the ingredients are evenly combined and the sugar has dissolved. The mixture should have a consistent pale-green colour.
Step 3: Strain the Mixture
Pass the mixture through a fine-mesh sieve into a clean jug. This catches any remaining matcha particles or undissolved ingredients that could interfere with dispensing.
Don’t skip this step. Even properly sifted matcha can form small lumps when mixed with liquid.
Step 4: Fill and Charge the Whipper
Pour the strained mixture into your clean cream whipper, making sure you don’t exceed the manufacturer’s maximum fill line.
Secure the head, insert a compatible food-grade cream charger and charge the whipper according to its instructions. Shake as recommended by the manufacturer to distribute the gas evenly.
If you’re unfamiliar with the equipment, our beginner’s guide to using a whipped cream dispenser explains the preparation, charging and dispensing process.
Refrigerate the whipper briefly if the mixture has warmed during preparation. Never attempt to open the whipper while it’s pressurised.
Step 5: Dispense the Matcha Foam
Hold the whipper in the dispensing position specified by its manufacturer and gently dispense the matcha foam over your prepared iced matcha latte.
Start with a modest amount, then add more if you’d like a thicker topping. The foam should be creamy enough to form a distinct layer while remaining soft enough to enjoy with the drink.
How to Make an Iced Matcha Latte with Cold Foam
While your foam chills, prepare the iced matcha latte that will sit underneath it.
A cold foam matcha latte starts with a regular iced matcha drink, finished with the creamy topping rather than mixing everything together.
Sift two teaspoons of matcha into a small bowl. Add 60 ml of warm water at approximately 70–80°C and whisk until smooth and lightly frothy.
Divide the matcha mixture between two tall glasses. Add your preferred sweetener and stir until combined.
Fill the glasses with ice, then pour 200 ml of cold milk into each one. Stir gently to combine the matcha and milk.
Finally, dispense a generous layer of matcha cold foam over each latte. The lighter green foam creates an attractive contrast with the drink underneath.
Serve immediately with a reusable straw. You can stir the foam into the latte or leave it on top and enjoy the different textures as you drink.
Ceremonial vs Culinary Matcha: Which Is Better?
Matcha is commonly sold in ceremonial and culinary grades, although these labels aren’t governed by a universal grading standard.
Ceremonial-grade matcha is generally marketed for drinking on its own. It often has a smoother flavour, brighter green colour and less noticeable bitterness, although quality varies between brands.
Culinary-grade matcha is usually intended for recipes where the tea is combined with other ingredients. Its stronger flavour can work well in cold foam, particularly when mixed with cream and sweetener.
For the best balance of flavour and price, choose a good-quality culinary matcha designed for drinks, or an affordable ceremonial-style matcha if you prefer a milder taste.
Avoid matcha that smells stale or has developed a dull brownish colour. Fresh powder generally produces a more appealing flavour and colour.
Why Cold Ingredients Make Better Matcha Foam
Temperature plays a bigger role in cold foam than you might expect. Cold thickened cream aerates more reliably and helps the finished foam maintain its texture.
Keep your milk and cream refrigerated until you’re ready to use them. If possible, chill the mixing jug as well.
The type of cream also affects the finished texture. Australian thickened cream is a reliable option, but you can learn more about different varieties in our guide to choosing the best cream for whipping.
The small amount of warm water used to dissolve the matcha shouldn’t be a problem once it’s combined with the cold ingredients. However, if the mixture feels warm, refrigerate it before charging or dispensing.
Don’t add ice cubes directly to the whipper. They’ll interfere with the equipment and aren’t necessary when the ingredients are properly chilled.
How to Fix Matcha Cold Foam That's Too Thin
If your foam comes out runny, there’s usually a straightforward explanation.
The Cream-to-Milk Ratio Is Too Low
Milk makes cold foam lighter, but too much reduces its ability to hold air. If the foam lacks body, increase the proportion of thickened cream in your next batch.
Try 175 ml of cream and 75 ml of milk instead of the original 150 ml to 100 ml ratio.
The Ingredients Aren't Cold Enough
Warm cream won’t produce the same texture as properly chilled cream. Refrigerate the mixture and whipper according to the manufacturer’s instructions before trying again.
The Whipper Needs More Shaking
Follow the manufacturer’s recommended shaking method and number of shakes. Too little shaking may produce uneven results, while excessive shaking can make the cream overly stiff.
The Matcha Mixture Contains Too Much Water
Only use enough warm water to dissolve the matcha. Excess water thins the cream mixture and can affect the finished foam.
If the foam still isn’t right, check that you’re using suitable whipping cream and that the whipper, charger and dispensing parts are compatible and functioning correctly.
Can You Make Matcha Cold Foam Ahead of Time?
Yes, preparing the mixture ahead can be useful when you’re making several iced drinks.
Mix and strain the ingredients, then refrigerate them in a covered container until you’re ready to fill the whipper. You can also prepare the foam in the whipper ahead of serving if the manufacturer permits refrigerated storage.
Keep dairy ingredients at 5°C or colder, follow their use-by dates and observe the equipment manufacturer’s storage guidance.
Our guide to storing whipped cream also has useful advice on keeping cream-based toppings refrigerated and maintaining their texture.
Don’t leave the whipper sitting out on a warm kitchen bench or in direct sunlight.
For the freshest presentation, prepare the iced matcha lattes separately and dispense the foam just before serving.
More Cold Foam Flavours to Try
Once you’ve mastered matcha cold foam, you can experiment with other flavours using the same basic approach.
Vanilla is an easy addition if you prefer a sweeter, softer matcha flavour. A little honey or maple syrup can also work, provided it dissolves completely, and the mixture is strained before entering the whipper.
If you’re interested in experimenting with different textures and cream-to-milk ratios, our main cold foam guide covers lighter, milk-based foam, as well as additional preparation tips.
For something sweeter, our salted caramel cold foam recipe offers a rich alternative that works beautifully over iced coffee.
Give Your Iced Matcha a Café-Style Finish
A good iced matcha latte doesn’t need much dressing up, but a layer of homemade matcha cold foam makes it feel like something you’d order at your favourite café.
The trick is getting the consistency right. Sift the matcha, strain the mixture, keep everything cold and use a balance of cream and milk that gives the topping enough body without making it too heavy.
Once you’ve found the texture you like, you can adjust the sweetness, try a little vanilla or experiment with different matcha powders. Make the latte as usual, finish it with a fresh layer of foam and enjoy it while it’s cold.
