For the short pastry, put flour, butter in flakes, sugar, salt, vanillin sugar, baking powder and egg into a mixing bowl and work through with the dough hooks of the hand mixer. Then knead quickly with cool hands to a smooth dough. Form into a roll (approx. 15 cm long) and cover and leave in a cool place for approx. 30 minutes. Grease 7 cake tins (12 cm Ø). Cut the dough into 7 slices.
Press one slice into each greased cake tin. Bake in the preheated oven (electric cooker: 175 °C/ gas: level 2) for about 25 minutes. Remove from the oven, allow to cool slightly, turn out of the tartlets and let them cool down on a grid. Let the raspberries thaw for 10-15 minutes. In the meantime, melt the chocolate in a water bath. Spread the tartlets with it. Let the chocolate set. For the topping, mix vanilla sugar and cream thickener. Put the sour cream and cream in a bowl, whisk with the whisk of the hand mixer, pour in the cream firming mixture and beat until stiff. Fold in raspberries.
