Apparently, Jonas Vileišis – one of the signatories of the Act of Independence of Lithuania – had a daughter, and this cake was her favourite treat in Vilnius. So even though this cake is more than a hundred years old, its taste is on par with modern desserts.
You will need:
For the sponge cake:
For the filling:
Make the sponge cake
Beat the egg yolks with the sugar until the mixture is almost white and fluffy. Beat the egg whites until they form a thick foam, then gradually add them to the yolk and sugar mixture. Add a pinch of salt, the flour, and the melted butter. Divide the mixture into six parts and pour each part into a round 22 cm baking tin. Bake in an oven preheated to 180°C for 12-14 minutes.
Make the filling
Beat the eggs, add the sugar and bring the mixture to a boil in a water bath (bain-marie), stirring the entire time. Remove the filling from the water bath and let it cool. Melt the chocolate in a bowl of hot water and add the butter at room temperature. Combine the egg and chocolate mixtures and add the cocoa powder.
Assemble the cake
Spread each sponge cake with 1/6 of the filling and stack. Sprinkle the top layer with cocoa powder.
Allow the cake to stand for one day so the layers can set and the sponge cake can absorb the filling.
