Mix flour, baking powder, sugar, vanillin sugar, salt and cinnamon well in a bowl. Peel, wash and finely grate the carrots. Stir oil into the flour mixture. Add the eggs one by one and stir in.
Finally, fold carrots and almonds into the dough. Grease a springform pan (24 cm Ø), fill in the dough and bake in a preheated oven (electric: 175 °C/ gas: level 2) for about 1 hour. Cover if necessary in between.
Let the cake cool down in the mould on a cake rack. In the meantime knead marzipan and 25 g icing sugar. Then colour the mixture orange with a few drops of yellow and 1-2 drops of red food colouring.
Shape 16 small carrots (weighing about 5 g). Cut some pistachio kernels into quarters and put 2 quarters as leaves into the carrot ends. Carve a grain into the finished carrots with a knife.
For the cream melt butter and let it cool down. In the meantime, stir cream cheese, icing sugar and vanilla aroma until creamy. Stir in the butter bit by bit. Spread the cream cheese mixture on the cake. Place a wreath with the carrots.
Finely chop the remaining pistachios and decorate the cake with them. Makes about 16 pieces.
