How to make
Beat the eggs with the sugar and add the flour, baking powder and milk, while still beating. Add cocoa and so on, until you've added everything and it homogenizes.
Pour the mixture into a greased and floured form and bake until ready. For the buttercream, beat the butter and sugar very well, divide it into 2 parts. To one add the vanilla and to the other, the fresh egg yolks, and mix each of them.
Divide the cooled cake layer carefully into two. Smear 2/5 cup (100 ml) sugar syrup on them.
Glue the two layers together with the yellow cream and smear the white cream on top. Make a decoration of your choice - you can sprinkle with nuts or chocolate glaze and arrange fruits.
