Beat the eggs, sugar, and scraped vanilla caviar in a mixer for 15 minutes at medium speed.

Add the sifted flour, Matcha tea powder, and the soft butter, mix the mixture with a spatula from the top to the bottom to obtain a homogeneous consistency.

Put the mixture into the cake pan properly greased and lightly floured.

Bake in a preheated oven at 180°C (356°F) for about 40-50 minutes, never open the oven before 35 minutes.

Do the toothpick test to check cooking, insert it in the center and it should come out clean.

After the time necessary to allow it to cool, remove it from the mold.

Make sure the sponge cake is cooled completely before slicing.

Slice the sponge into three layers.

Soak the gelatin in cold water.

Work the egg yolks in a mixer at maximum speeds with 100g (7 tbsps) sugar until the mixture is light and smooth.

After the gelatin has completely soaked, squeeze it with your hands and make it completely dissolve in a cup with warm whipping cream.

Slowly drip the whipping cream-gelatine mixture into the egg cream.

Add the mascarpone cheese, while continuing to mix it little by little amalgamating it very well to avoid lumps.

In a clean container whip the egg whites.

Once you’ve whipped the egg whites, incorporate them into the mixture of mascarpone with a spatula moving from top to bottom until you get a smooth cream.

The Matcha tea powder is dissolved in water, do not infuse.

Heat the water and pour it into a cup, avoid reaching the boiling point (therefore remaining around 80°C, 176°F ).

Mix the tea powder in the water with a small whisk, if you don’t have the bamboo whisk (Chasen), which should be kept in water for a few seconds before being used (bamboo whisk) – mix with slow movements simulating the shape of an eight until the powder dissolved in the water.

Place the first base layer onto a 6-inch round springform pan.

Brush 1/4 of the soaking Matcha syrup onto the cake then spread with the mascarpone cream.

Repeat with the remaining layers and cover the top with the remaining mascarpone cream.

Place it into the fridge for 3-4 hours.

After, remove the Matcha Tiramisu` from the springform pan and garnish with sponge cake crumbles, as I did, or dust the surface with some powdered matcha tea.
