Cream fat, sugar, vanillin sugar and salt with the whisk of the hand mixer. Stir in the eggs one after the other. Mix flour and baking powder and stir in portions. Grease a saddle of venison (30 cm long; 1 litre capacity) well and sprinkle thickly with breadcrumbs.
Add the dough and smooth it down. Place three rows of peppermint bars in the dough and press them in lightly. Leave 2-3 tablets to decorate. Bake in the preheated oven (electric: 175 °C/ gas: level 2) for approx. 45 minutes.
Let it cool down on a cake rack. Turn out of the mould and let it cool completely. Sprinkle with icing sugar and pistachios. Quarter the remaining bars and decorate the cake with them. Makes about 18 pieces.
