For the dough, boil 1/4 litre of water, salt and fat in a pot. Add the flour and stir over medium heat until the dough comes off the bottom of the pot as a lump. Stir in 1 egg, let the dough cool down a little and gradually stir in the remaining eggs until a shiny dough is formed.
Pour the dough into a piping bag with a large star-shaped spout. From half of the dough, squirt 8 spots onto a baking tray lined with baking paper. Bake in a preheated oven (electric cooker: 200 °C/ gas: level 3)) for about 15 minutes.
Cut open the cream puffs immediately and let them cool down. Bake 8 more cream puffs from the remaining dough. Soak the gelatine for the filling. Mix quark, vanillin sugar, sugar and slibovitz. Squeeze the gelatine, dissolve and stir into the quark.
Whip cream until stiff and fold in. Spread the plum puree on the cream puffs. Pour the quark cream into a piping bag with a star-shaped spout and squirt onto the plum jam. Mix icing sugar, cinnamon and 2-3 tablespoons of water to a glaze.
Spread the tops of the cream puffs with it, place on the quark and leave to dry.
