Drain the peaches on a sieve. Let the raspberries thaw a little. Melt butter in a pot. Mix 750 g flour, sugar, vanillin sugar and salt in a bowl. Add hot butter and knead into crumbles with the dough hooks of the hand mixer
Grease a baking tray (32 x 37 cm) and spread a good half of the crumbled dough evenly on it as a base and press it down. Add 1 tbsp. flour to the remaining dough, toss with the crumbles and allow to cool. Stir the jam until smooth, spread on the crumble base
Cut the peach halves into quarters, spread on the base with the raspberries and sprinkle with the remaining crumbles. Bake in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) on the bottom shelf for approx. 30 minutes. Let the cake cool down on the tray, dust with icing sugar, then cut into pieces. Vanilla ice cream tastes good with it
waiting time approx. 2 hours
