Beat the lukewarm fat, sugar, vanillin sugar and salt until foamy. Stir in the eggs one after the other. Sift flour, starch and baking powder and alternately add cream. Halve the pralines and fold in. Grease a ring cake tin (2.3 litres capacity) and sprinkle with breadcrumbs. Pour 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. 45 minutes.
Let the cake rest in the tin for approx. 10 minutes and turn it over onto a grid. Let it cool down. Melt the cake glaze in a water bath. Mix in nuts and pour the icing on the cake. Let it set. Cut the cake into pieces and serve
