Mix flour, baking powder, salt and 100 g sugar. Add 1 egg and butter in pieces. Quickly knead into a smooth shortcrust pastry. Roll out the dough round (approx. 32 cm Ø) on a floured work surface. Grease a springform pan (26 cm Ø), put the dough into it and press the rim. Place the mould in a cool place for approx. 30 minutes. In the meantime mix pudding powder and 40 g sugar. Stir with 100 ml milk until smooth.
Bring 400 ml milk to the boil, remove from the stove. Stir in pudding powder. Let simmer for about 1 minute while stirring. Stir in the poppy seed filling, let it cool down a bit. Stir in advocaat and 150 g sour cream. Pour the mixture onto the base and smooth it down. Stir 3 eggs, 125 g sugar and vanilla sugar until thick and creamy. Stir in 300 g sour cream. Carefully pour onto the poppy seed mixture and smooth it down. Bake in the preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: level 2) for approx. 60 minutes. Cover the last 10 minutes of baking time if necessary. Leave to cool down with the oven door open. Knead marzipan with icing sugar. Colour one third of the mixture green with food colouring.

Form small balls from half of the green marzipan, place them in the middle of the flowers and press them flat. Roll the remaining marzipan into several thin strands (each approx. 6 cm long). Whip the cream until stiff, fill into a piping bag with star-shaped spout. Remove the cake from the mould. Spray a cream rim onto the cake and sprinkle with eggnog. Decorate with marzipan decoration and chocolate rolls
