Place the eggs, 150 g sugar and 1/2 packet of vanilla sugar in a mixing bowl and whisk until foamy. Mix flour and baking powder and stir in briefly. Add oil and lemonade while stirring and work everything into a smooth dough. Grease a cloverleaf cake tin (outer dimensions 25 cm Ø; inner dimensions 22 cm Ø; 1 1/4 litre capacity) and sprinkle well with breadcrumbs. Fill in the dough and smooth it down. Bake in the preheated oven (electric cooker 175 °C/ convection oven: 150 °C/ gas: level 2) for approx. 35 minutes.
Let cool slightly on a cake rack, turn out of the tin and let cool completely. For the cream, mix jelly powder with 150 ml water in a small pot and let it swell for 5 minutes. Add 4 tablespoons of sugar and heat while stirring until everything is dissolved (do not boil !). Add 100 ml of cold water and chill the jelly. In the meantime, stir cream cheese, lemon juice, 100 g sugar and 1 packet of vanilla sugar until smooth. Whip cream until stiff. When the jelly begins to set, first stir in the cream cheese and then the cream in portions. Cut the cake once horizontally. Spread the cream on the bottom base and place the 2nd base as a lid on top. For the decoration, prepare jelly according to the package instructions with half the amount of water and fill into a flat form. Turn out when cold.
