Drain the cherries well. Mix fat, sugar, vanilla sugar and salt with the whisk of the hand mixer for about 5 minutes until creamy. Add the eggs one after the other and stir in. Mix flour, sauce powder and baking powder and stir in alternately with the liqueur in portions.
Fold in the cherries. Grease a ring cake tin (23 cm Ø, approx. 2.5 litres capacity) and sprinkle with breadcrumbs. 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 45-50 minutes.
Leave to cool on a cake rack for about 10 minutes. Turn out of the tin and let it cool completely. Dust with icing sugar and decorate with mint.
