For the coconut mass, beat the sugar and 7 eggs with the whisk of the hand mixer until foamy. Add the coconut cream and quark and stir in. Sift 80 g starch on top and fold in. Pour the mixture onto a greased and floured fat pan of the oven (32 x 39 cm) and smooth it down. For the blueberry mixture, mix yoghurt, 3 eggs and semolina. Sift 40 g starch on top and fold in.
Pour blobs onto the coconut mass and draw streaks with a fork. Bake the cake in a preheated oven (electric cooker: 175 °C/ convection oven: not suitable/ gas: level 2) for approx. 60 minutes. Take the cake out of the oven and let it cool down on a cake rack. Cut into 20 pieces. To decorate, drain the blueberries and decorate the pieces with the berries
