For the crumbles, mix 300 g flour, 1 packet of vanillin sugar, salt, 150 g sugar, 1 egg, 150 g fat and aniseed with the dough hooks of the hand mixer. Then work into crumbles with your hands and chill. Peel, quarter, core and cut the pears into slices. Sort blackberries. Mix 250 g fat, 250 g sugar, 1 packet vanilla sugar and salt with the whisks of the hand mixer. Stir in 4 eggs one after the other. Mix 200 g flour, starch and baking powder and stir in.
Grease the fat pan of the oven (32 x 39 cm). Fill in the sponge mixture and smooth it down. Spread pears and blackberries on top. Sprinkle crumbles evenly over it. Bake in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for approx. 40 minutes. Remove from the oven, allow to cool on a grid and cut into pieces
