Drain the cherries, let them drip off. For the crumbles, mix flour, 80 g sugar, butter and 100 g coconut flakes with the dough hooks of the hand mixer to form crumbles and chill. In the meantime, mix quark, sour cream, 500 g sugar, lemon juice, eggs, pudding powder and semolina.
Fold the cherries into the quark mixture. Pour the mixture into a greased and floured oven pan (32 x 39 cm) and smooth it down. Bake in the preheated oven (electric cooker: 175 °C/ convection oven: not suitable/ gas: level 2) for 50-60 minutes.
After 30 minutes baking time, spread the crumble evenly on the cake and bake to finish. Remove the cake from the oven, place on a cake rack and allow to cool. Cut the cake into 30 cubes and sprinkle with remaining coconut flakes.
Whipped cream is delicious with it.
