Bring milk to the boil and remove from the stove. Stir in poppy seeds, a few dashes of sweetener, lemon peel and cinnamon and let it swell for about 10 minutes. In the meantime, separate the eggs. Cream egg yolk, vanilla pulp, 100 g diabetic sweetener and 2 teaspoons of sweetener. Stir in curd cheese and pudding powder. Beat the egg whites in portions with 1 pinch of salt until stiff. Fold into the quark mixture.
Remove 6-8 tablespoons of quark mixture and mix with the poppy seed filling. Smooth the rest of the quark mixture in a greased fat pan of the oven (32 x 37 cm). Spoon the poppy-quark mixture onto the surface. Use a fork to draw a circle through the blotches and marble them slightly. Bake the cake in a preheated oven (electric cooker: 175 °C/ convection oven: not suitable/ gas: level 2) for 40-45 minutes. Let them cool down. Dust the cake with 20 g diabetic sweetness and cut into pieces
