Step-by-Step Instructions

Step 1: Prepare the Crust

1. Preheat your oven to 350°F (175°C). Line an 8-inch springform pan with parchment paper or lightly grease it.
2. In a mixing bowl, combine the almond flour, sweetener, and salt. Add the melted butter and mix until the dough resembles coarse sand.
3. Press the mixture evenly into the bottom of the prepared pan to form the crust.
4. Bake for 10–12 minutes, or until lightly golden. Let the crust cool completely.

Step 2: Make the Matcha Paste

1. 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

1. In a small bowl, sprinkle the gelatin over the cold water and let it bloom for 5 minutes.
2. Microwave the bloomed gelatin for 10–15 seconds, or until fully dissolved. Stir it into the cooled matcha paste.

Step 4: Make the Mousse

1. In a large mixing bowl, beat the heavy cream, powdered sweetener, and vanilla extract with a hand mixer until soft peaks form.
2. Gently fold the matcha paste into the whipped cream until fully combined and no streaks remain.

Step 5: Assemble the Cake

1. Pour the matcha mousse over the cooled crust, spreading it evenly with a spatula.
2. 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

1. Use High-Quality Matcha : Ceremonial-grade matcha provides the best flavor and vibrant color compared to culinary-grade matcha.
2. Don’t Overmix the Mousse : Overmixing can deflate the whipped cream, resulting in a denser mousse. Fold gently to maintain airiness.
3. Adjust Sweetness : Start with a smaller amount of sweetener and adjust to your preference, as matcha can vary in bitterness.
4. Make Ahead : This cake can be made up to 2 days in advance and stored in the refrigerator until ready to serve.
5. Freeze for Convenience : Store leftover slices in a freezer-safe container for up to 3 months. Thaw in the refrigerator before serving.

3. Coconut Cream Version : Replace heavy cream with coconut cream for a dairy-free, tropical-inspired mousse.
4. Mini Cakes : Use mini springform pans or muffin tins to create individual-sized cakes perfect for portion control or gifting.

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.
