Put flour, 100 g sugar, butter in flakes, vanillin sugar, salt and egg in a large bowl. Mix with the dough hooks of the hand mixer. Then work into crumbles with your hands. Grease 4 flat, ovenproof (oval, max. 17 cm long, 12 cm wide) portion forms. Mix raspberries and 3 tablespoons of sugar and fill into the moulds.
Spread crumbles on top. Bake in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for 25-30 minutes. Remove from the oven, place on a rack and allow to cool slightly. Place 1 scoop of vanilla ice cream on each, decorate with mint and serve immediately
