Warm the milk lukewarm. Put 300 g of flour in a bowl and make a depression in the middle. Add yeast, 1 teaspoon of sugar and 4 tablespoons of warm milk into the hollow and stir a little. Cover with a cloth and leave to rise in a warm place for about 15 minutes. For the crumbles, mix 150 g flour, 50 g sugar, vanillin sugar, 75 g fat and chocolate flakes into crumbles using the dough hooks of the hand mixer.
Put them in a cold place. Heat the rest of the milk again and pour it into the yeast dough. Add egg, 50 g sugar, salt and 50 g soft fat. Use the dough hooks of the mixer for about 4 minutes to form a smooth dough. Cover and leave to rise in a warm place for about 30 minutes. Pour the cherries onto a sieve, drain and mix with the jam. Knead the yeast dough again and divide it into 8 equal pieces. Form 8 oval thalers from them. Place on 2 baking trays lined with baking paper. Spread cherries on top and sprinkle with the crumbles.
