Ingredients You’ll Need
Here’s what you’ll need to make Keto-Friendly Matcha Mousse Cake:
For the Crust:
- 1 ½ cups almond flour
- ¼ cup granulated erythritol or monk fruit sweetener
- ¼ teaspoon salt
- 6 tablespoons unsalted butter, melted
For the Matcha Mousse:
- 2 teaspoons matcha powder (high-quality ceremonial grade)
- 2 tablespoons hot water
- 1 cup heavy cream
- ¼ cup powdered erythritol or monk fruit sweetener
- 1 teaspoon vanilla extract
- 1 teaspoon unflavored gelatin
- 2 tablespoons cold water
For Garnish (Optional):
- Fresh berries (e.g., raspberries or strawberries)
- Whipped cream
- Additional matcha powder for dusting
Step-by-Step Instructions
Step 1: Prepare the Crust
- Preheat your oven to 350°F (175°C). Line an 8-inch springform pan with parchment paper or lightly grease it.
- In a mixing bowl, combine the almond flour, sweetener, and salt. Add the melted butter and mix until the dough resembles coarse sand.
- Press the mixture evenly into the bottom of the prepared pan to form the crust.
- Bake for 10–12 minutes, or until lightly golden. Let the crust cool completely.
Step 2: Make the Matcha Paste
- In a small bowl, whisk together the matcha powder and hot water until smooth and free of lumps. Set aside to cool.
Step 3: Prepare the Gelatin
- In a small bowl, sprinkle the gelatin over the cold water and let it bloom for 5 minutes.
- Microwave the bloomed gelatin for 10–15 seconds, or until fully dissolved. Stir it into the cooled matcha paste.
Step 4: Make the Mousse
- In a large mixing bowl, beat the heavy cream, powdered sweetener, and vanilla extract with a hand mixer until soft peaks form.
- Gently fold the matcha paste into the whipped cream until fully combined and no streaks remain.
Step 5: Assemble the Cake
- Pour the matcha mousse over the cooled crust, spreading it evenly with a spatula.
- Refrigerate the cake for at least 4–6 hours, or until the mousse is set and firm.
Step 6: Garnish and Serve
Once set, remove the cake from the springform pan. Dust with additional matcha powder or garnish with fresh berries and whipped cream. Slice and serve chilled.
Tips for the Best Matcha Mousse Cake
- Use High-Quality Matcha : Ceremonial-grade matcha provides the best flavor and vibrant color compared to culinary-grade matcha.
- Don’t Overmix the Mousse : Overmixing can deflate the whipped cream, resulting in a denser mousse. Fold gently to maintain airiness.
- Adjust Sweetness : Start with a smaller amount of sweetener and adjust to your preference, as matcha can vary in bitterness.
- Make Ahead : This cake can be made up to 2 days in advance and stored in the refrigerator until ready to serve.
- Freeze for Convenience : Store leftover slices in a freezer-safe container for up to 3 months. Thaw in the refrigerator before serving.
Variations to Try
While the classic version is divine, here are some creative twists to try:
- Chocolate Matcha Combo : Swirl melted sugar-free chocolate into the mousse for a decadent twist.
- Layered Cake : Add a thin layer of sugar-free berry compote between the crust and mousse for a fruity contrast.
- Coconut Cream Version : Replace heavy cream with coconut cream for a dairy-free, tropical-inspired mousse.
- Mini Cakes : Use mini springform pans or muffin tins to create individual-sized cakes perfect for portion control or gifting.
- Gluten-Free Option : This recipe is naturally gluten-free, but ensure all ingredients (like extracts) are certified gluten-free if needed.
Serving Suggestions
Matcha Mousse Cake is versatile enough to serve in a variety of settings:
- For Afternoon Tea : Pair with a cup of green tea, black tea, or sparkling water for a refreshing pairing.
- At Parties : Arrange slices on a dessert platter alongside other low-carb treats like cookies or truffles.
- For Special Occasions : Decorate with edible flowers or gold leaf for an elegant touch at weddings, anniversaries, or holidays.
- With Beverages : Serve alongside coffee, tea, or a glass of dessert wine for a sophisticated pairing.

Frequently Asked Questions (FAQs)
Q: Can I use coconut flour instead of almond flour? A: Coconut flour absorbs more moisture, so you’ll need to adjust the ratio. Use ¼ cup coconut flour instead of almond flour and increase the eggs or liquid to compensate.

Q: Can I freeze this cake? A: Absolutely! Wrap individual slices tightly in plastic wrap and store them in a freezer-safe container for up to 3 months. Thaw in the refrigerator before serving.
Q: How do I prevent the mousse from being too dense? A: Ensure the whipped cream is beaten to soft peaks and fold the matcha paste gently to avoid deflating the mixture.
Q: Can I make this cake nut-free? A: Yes! Replace almond flour with sunflower seed flour or a gluten-free flour blend for a nut-free alternative.
