Chocolate, matcha & mint cake

Ingredients

Chocolate sponge biscuit

4 eggs

80 grams (2.82 ounces) sugar

80 grams (2.82 ounces) flour

30 grams (1.06 ounces) cocoa powder

40 grams (1.41 ounces) butter

6 grams (0.21 ounces) baking powder

Soaking

150 grams (5.29 ounces) milk

2 drops mint oil

50 grams (1.76 ounces) sugar

Mint cream-mousse

10 grams (0.35 ounces) gelatin

60 grams (2.12 ounces) water

80 grams (2.82 ounces) sugar

300 grams (10.58 ounces) whipping cream

250 grams (8.82 ounces) mascarpone cheese

2 teaspoons matcha powder

3 drops mint oil

Instructions

Step 1

Note: We don't use fresh mint here, as it will not give such a bright taste as edible essential oil. Peppermint oil or "mint flavor" oil can be bought in pastry shops. If you don't want to use matcha tea, you can use green dye or just leave the mousse white.

Step 2

Whip the eggs with sugar until they are fluffy and white. It's important to achieve a light and airy texture for the best sponge cake outcome.

Step 3

Sift the cocoa powder and flour together. Pour this dry mixture into the whipped eggs and mix until smooth using a spatula by hand or on low speed with a mixer. Don't overmix to avoid deflating the batter.

Step 4

Add the melted butter and mix lightly. Butter should be melted but not hot.

Step 5

Pour the batter into two 16cm (6.30 inch) molds with the height of the dough not exceeding 7cm (2.75 inch).

Step 6

Bake the sponge at 338F (170C) for about 30-40 minutes. Check readiness with a skewer. Every oven is different; start checking at 30 minutes.

Step 7

Cut off the top crust from the finished biscuits and cut each biscuit in half.

Step 8

Combine all soaking ingredients, heat gently, and mix until smooth. Soak the biscuits. Soak each layer evenly for consistent moisture.

Step 9

Soak the gelatin in cold water. Allow it to sit until bloomed and fully hydrated.

Step 10

Combine mascarpone and sugar in a mixer bowl. Stir vigorously until smooth.

Step 11

Whip the cream until medium thick. Stop as soon as the cream starts holding its shape.

Step 12

Heat the gelatin for a few seconds in the microwave until it becomes liquid. Do not overheat it.

Step 13

With the mixer running at medium speed, pour the gelatin into the cheese mixture, immediately followed by the whipped cream and mint oil. Mix until smooth.

Step 14

Assemble the cake with the cream-mousse. Ensure even layers for a polished finish.

Equipment

Mixing Bowls

You'll need a few bowls of different sizes. Use one for whisking the eggs and sugar, another for sifting the dry ingredients, and one more for the cream-mousse mixture.

Mixer

A stand mixer will make the task easier, but a hand mixer works just as well. Just remember to adjust the speed as needed.

Sifter

A fine mesh sieve is ideal for sifting flour and cocoa together, ensuring a smooth and lump-free batter.

Spatula

A silicone spatula is perfect for gently folding the ingredients together without deflating the mixture.

Baking Molds

Two 16cm (6.30 inch) molds will help you get the perfect shape and size for your cake layers.

Microwave

You'll need this to heat the gelatin. Be cautious not to overheat.

Faq

How do I know if my cake is baked through?
Insert a skewer into the center of the cake. If it comes out clean, the cake is done. If it has batter clinging to it, bake a bit longer and check again.
Can I use fresh mint instead of mint oil?
No, fresh mint will not give you the bright and concentrated flavor that mint oil provides. Mint oil is essential for this recipe.
What can I use if I don't have matcha?
If you don't want to use matcha, you can use green food coloring. Alternatively, you can leave the mousse white, but it won't have the slight matcha flavor.
Can I make this cake ahead of time?
Yes, you can bake the sponge a day in advance. Just keep them tightly wrapped in plastic wrap. Assemble the cake the day you plan to serve it for the best texture and flavor.
How can I make my cake layers even?
Make sure your batter is evenly distributed between the molds. You can also use a kitchen scale to ensure each mold gets an equal amount of batter.
How long can I store the assembled cake?
The cake can be stored in the refrigerator for up to 3 days. Keep it covered to prevent it from drying out or absorbing other refrigerator odors.
