Cream fat, sugar, vanillin sugar and salt. Stir in the eggs one after the other. Mix nuts, except for 1 tablespoon chopped nuts, baking powder and flour. Alternately stir in rum. Grease a ring cake tin ("Flora"; 24 cm Ø; 3 litres capacity) and dust with flour.
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 50-60 minutes. Remove from the oven, allow to cool for 10 minutes and place on a cake rack to cool. Dust the cake with icing sugar and sprinkle with remaining nuts. Whipped cream tastes good with it
