Roast the nuts in a pan without fat. Finely chop 2/3 of the nuts. Wash the plums, grate dry, halve and stone them. Cut fat into pieces. Cream 170 g sugar, fat and vanilla sugar with the whisk of the hand mixer.
Stir in the eggs one by one. Mix flour, chopped nuts and baking powder and stir in alternately with the milk. Fill the dough into a greased and flour-spreaded springform pan (26 cm Ø) and smooth it down. Cover cake tightly with plums. Mix 1 tablespoon sugar and some cinnamon and sprinkle the plums with it. Bake the cake in a preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for 40-45 minutes. Remove the cake from the oven. After about 20 minutes, remove the cake from the tin and let it cool on a cake rack. Before serving, dust the cake with icing sugar and decorate with the remaining nuts.
