Wash the cherries, drain well, stone them and put them on a sieve. Cut marzipan into fine cubes and mix with 1 teaspoon of flour. Put 250 g soft fat, 200 g sugar, vanillin sugar, lemon peel and salt into a mixing bowl and whisk until creamy. Add the eggs one by one alternating with the cornflour and stir well. Mix 250 g flour and baking powder and finally stir in briefly. Grease the oven pan (approx. 38x34 cm) well and dust with flour.
Spread the dough evenly on top. Mix drained sour cherries with 1 tablespoon flour. Sprinkle the cherries and marzipan on the dough and bake in the preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: level 2) for approx. 20 minutes. In the meantime heat up 100 g fat and 125 g sugar. Add almonds first, then milk and remove from the heat. Spread the almond icing as small blobs on the pre-baked cake and bake for another 20 minutes
