Chocolate Cake

Ingredients

Half a cup of butter
A cup and a half of sugar
A tablespoon of cognac
The yolks of five eggs, well beaten
A tablespoon of butter with a teaspoon of vanilla essence
Two cups of flour
Four teaspoons of baking powder
A tablespoon and a half of cocoa
A teaspoon of carbonate of ammonia
A cup of yogurt
The whites of five eggs, beaten well until stiff.

Method:

Beat the butter well, then add gradually the sugar, pounded and sifted, together with the cognac, and beat well. After that add the egg yolks, then beat in the butter and the essence, and add gradually, with careful stirring, the flour, mixed and sifted with the baking powder, the cocoa, and the ammonia, alternating with the yogurt, until the flour and the yogurt are used up. Finally fold in the egg whites, turning them over with deliberation, then pour the mixture into a wide baking tray and bake it. After the baking — that is, after it has cooled — you may cut it into shapes with cutters. Lay the pieces in pairs and fill the inside of them with cream.
