Wuzetka is a traditional cake originating from Warsaw. The cake consists of chocolate sponge cake that's filled with whipped cream and covered with chocolate icing. It's usually made with a combination of flour, eggs, sugar, butter, cocoa powder, whipping cream, rum, gelatin, and plum jam.
The icing is made with a combination of butter, milk, and dark chocolate. Once prepared, the bottom layer is drizzled with jam and rum, the whipped cream mixture is spread over it, and the top sponge layer is placed on top. The chocolate icing is poured over the cake, and when it sets, the wuzetka is cut into cubes.
