Method

Base

Heat an oven to 180C with a fan.

Line the round cake tin (with a diameter of 25cm) with baking parchment. 

Separate the whites from the yolks into two bowls. 

Place the whites into the mixing bowl. 

Add a pinch of salt and beat to a stiff foam using a hand mixer at high speed.

Add gradually sugar, spoon by spoon, and whisk until dissolved.

Add yolks, one at a time, still mixing until combined. The mixture should be light and fluffy at this stage.

Sift the flour, potato starch, cacao powder and baking powder and add to the egg mixture. Fold with the spatula. 

Do not use a whisk at this time.

Gently transfer the dough onto the tin and even out. 

Bake for 25 to 30 minutes. 

Take the hot base out of the oven. Carefully drop the base in the tin on the floor from a height of around 30 cm and cool down at room temperature. This allows to settle and levelling of the base.

Once cooled down, cut into 2 tops.

Spread the jam from the inside of the bottom part.

Filling

Pour the double cream into the mixing bowl and whisk using a mixer at high speed. Gradually add sugar.

It will take a few minutes until the filling is done. Do not overmix. The cream must be fluffy not too stiff.

Prepare the same round cake tin you used to bake the base and place the first top inside (side with a jam upwards).

Spread the cream over the base and cover with the top making a cake sandwich.

Topping

In a medium pot melt the butter.

Add sugar and cacao powder.

Stirring adds slowly milk, spoon by spoon, and combine all ingredients.

The topping is ready when is glassy and smooth.  

Pour onto the top of the cake.

You can decorate with sprinkles.
