This matcha mousse is a no-bake, no-gelatin dessert that sets in the fridge using whipped aquafaba for lift and full-fat coconut milk plus Greek yogurt for the creamy base. It comes together in about 25 minutes of active work, then chills for at least an hour. The honest reason to make it: the flavor is genuinely interesting — earthy, lightly bitter matcha against tangy yogurt — and the texture is lighter than you’d expect from something with no eggs and no heavy cream.
Before you start
Two things decide whether this mousse works. First, dissolve the matcha completely in the warm coconut milk before anything else touches it. Matcha powder clumps on contact with cold liquid and those clumps don’t disappear later — you’ll end up with green specks and uneven flavor. Keep the heat low and whisk constantly for the full 2–3 minutes. Second, whipping aquafaba by hand takes real effort — 5 to 7 minutes of vigorous whisking is not an exaggeration. Soft peaks mean the foam holds a gentle curve when you lift the whisk; if it’s still liquid and frothy, keep going. Under-whipped aquafaba collapses when folded in and the mousse will be dense rather than airy. A hand mixer or stand mixer makes this much easier if you have one.
Substitutions that actually work
- Aquafaba: Use the liquid from a can of plain, unsalted chickpeas. Salted or seasoned varieties can affect the flavor. Drain it straight from the can — no need to reduce it for this recipe.
- Coconut milk: It must be full-fat canned coconut milk, not the refrigerated carton kind. The higher fat content is what gives the base its body. Shake or stir the can well before measuring, since the fat and liquid separate.
- Greek yogurt: A full-fat or 2% Greek yogurt works best. Fat-free versions are thinner and can make the mousse slightly watery. If you want a fully dairy-free version, a thick coconut yogurt is a workable swap.
- Honey vs. maple syrup: Both work. Maple syrup keeps it vegan and has a slightly more neutral sweetness; honey adds a faint floral note that pairs well with matcha. Either way, 3 tablespoons is on the lightly sweet side — taste the base before folding in the aquafaba and add a little more if you want it sweeter.
Mistakes to avoid
- Adding the matcha mixture while it’s still hot: Hot liquid deflates the whipped aquafaba almost instantly. Let the coconut milk and matcha mixture cool until it’s just warm to the touch before combining it with the yogurt.
- Stirring instead of folding: Once the aquafaba is whipped, fold it into the matcha-yogurt base with a spatula using slow, wide strokes from the bottom up. Stirring knocks out the air you just worked to build in.
- Skipping the full chill time: One hour is the minimum. The mousse firms up noticeably between the 1-hour and 2-hour marks. If it looks a little loose when you pour it into glasses, that’s normal — it sets as it chills.
- Using the wrong grade of matcha: Culinary-grade matcha is specified for a reason — it’s meant to hold its flavor when mixed into other ingredients. Ceremonial-grade is finer and more expensive, but it doesn’t perform better here. Skip the garnish of extra matcha on top — it goes bitter and powdery within an hour of sitting in the fridge, and it’s not worth the extra dish.
Keeping it fresh
Cover each glass with plastic wrap pressed directly onto the surface of the mousse and refrigerate for up to 3 days. The texture is best on day one and two; by day three it softens slightly but still tastes good. This mousse does not freeze well — the aquafaba foam breaks down and the texture turns grainy after thawing. For make-ahead purposes, you can prepare the matcha-yogurt base up to 24 hours in advance and keep it covered in the fridge, then whip and fold in the aquafaba the day you plan to serve it.
Healthy Matcha Mousse
Equipment
- Whisk
- Mixing Bowls
- Small saucepan
- Spatula
- Serving glasses
Ingredients
- 1 cup coconut milk full-fat, canned
- 2 tablespoons matcha powder culinary grade
- 3 tablespoons honey or maple syrup for a vegan option
- 1 teaspoon vanilla extract pure
- 1 cup Greek yogurt plain, unsweetened
- ½ cup aquafaba liquid from a can of chickpeas
Instructions
- In a small saucepan over low heat, whisk together the coconut milk and matcha powder. Heat gently until the matcha is fully dissolved, giving off a bright green aroma, about 2-3 minutes. Remove from heat and let it cool slightly.
- Stir in the honey (or maple syrup) and vanilla extract into the warm matcha mixture until well combined, allowing the flavors to meld.
- In a mixing bowl, whisk the Greek yogurt until smooth. Fold in the matcha mixture gently, ensuring a smooth, consistent texture.
- In a separate bowl, whip the aquafaba using a whisk until soft peaks form. This should take about 5-7 minutes of vigorous whisking. Alternatively, use a stand mixer to expedite the process.
- Gently fold the whipped aquafaba into the matcha-yogurt mixture using a spatula. Aim for a light, airy consistency, maintaining the mousse's fluffiness.
- Divide the mousse among serving glasses and refrigerate for at least 1 hour before serving, allowing the flavors to develop and the mousse to set.
Notes
- For a more robust matcha flavor, consider dusting the top with a pinch of matcha powder before serving.
- To further enhance the visual presentation, garnish with fresh mint leaves or a scattering of jasmine flowers.

Common questions
Can I make this without aquafaba?
Not easily and get the same result. Aquafaba is the structural element that makes this a mousse rather than a thick pudding. If you’re not avoiding eggs, two stiffly beaten egg whites folded in the same way will work as a direct substitute.
My aquafaba won’t form peaks — what’s wrong?
The most common cause is grease on the bowl or whisk, which prevents the foam from forming. Wipe both with a paper towel dampened with a little white vinegar or lemon juice before you start, then dry thoroughly. Also make sure the aquafaba itself is cold — it whips more reliably straight from the fridge.
How do I know if my matcha is fully dissolved?
Tilt the saucepan and look at the liquid — it should be uniformly bright green with no dark specks or streaks. If you see clumps, keep whisking over low heat for another minute. A small fine-mesh sieve to sift the matcha powder into the coconut milk before heating also helps prevent clumping in the first place.
Can I make this in one large bowl instead of individual glasses?
Yes, a medium serving bowl works fine. The chill time stays the same, but scooping it to serve will deflate it a little — individual glasses just look neater and hold the texture better when portioned.
