What you need:
Milk - I used cow's milk but almond milk is also suitable.
Unsalted butter - make sure it is softened.
Granulated sugar
eggs - I used large eggs.
Matcha - be sure to use a good quality matcha powder like our Sakura Matcha. Namely, the aroma makes all the difference.
All-purpose flour - also called ordinary flour.
Gelatin sheets - they will help to fix the foam.
White chocolate - I used Nestlé white chocolate buttons which I melted in the microwave.
Heavy cream - this is the type of cream you use for whipping.

Preparation:
Matcha sponge cake
- Preheat the oven to 175 ° C. For this recipe you will need an 18cm cake pan and an 20cm cake pan.
- Put the milk and butter in a small microwave-safe bowl and heat it for 30 seconds or until the butter is melted. Set aside to cool.
- Add the eggs, sugar and vanilla extract to a large mixing bowl. Sift the flour and matcha powder into the bowl and use a spatula to gently fold them in until there are no more large lumps of flour.
- Pour into an 20-inch baking pan lined with parchment paper and bake for 15 to 20 minutes.
- While the cake is baking, line the bottom of an 18 cm (10 cm high) cake pan with parchment paper. Cover the sides with acetate.
- Use an 18cm cookie cutter to cut out the cake. Place it in the 18 cm cake pan. Using a damp cloth, wipe off any crumbs that may have settled on the acetate when inserting the cake. Set aside.
White chocolate mousse
- Add cold water to a large mixing bowl. Add the 9 gelatin sheets and let soak.
- Add water, 100ml cream and melted white chocolate to a microwave-safe bowl and whisk until combined. Cook in the microwave for 90 seconds.
- Take 6 gelatin sheets out of the water and squeeze the water well in your hands. Add them to the hot mixture, whisking each time. Let cool to room temperature. Do not let the mixture cool for too long, otherwise it will harden.
- Add the rest of the cream to a large bowl with the vanilla extract. Use an electric mixer to whip until you get stiff peaks. Add the cooled white chocolate mixture and use a spatula to incorporate it into the whipped cream.
- Place the mixture on the cake layer in the 18 cm pan. Use the back of a spoon to even it out. Place in the refrigerator.
Matcha mousse

- Add the rest of the cream to a large bowl with the vanilla extract. Use an electric mixer to whip until you get stiff peaks. Add the cooled white chocolate mixture and use a spatula to incorporate it into the whipped cream.
- Spoon the mixture onto the white chocolate mousse. Use the back of a spoon to even it out. Place the cake in the freezer for 4 hours to set completely.
- To finish the cake, carefully remove it from the pan. Use a small sieve to sprinkle the matcha powder. Slowly remove the cake from the acetate and cut it into slices for serving.
Good tasting !
