Wash and clean the gooseberries and let them drain well in a sieve. Chop the hazelnuts. Put flour, butter in pieces, sugar, salt and cinnamon in a large mixing bowl. Mix with the dough hooks of the hand mixer. Then work into crumbles with your hands. Fold in gooseberries and hazelnuts
Spread the crumble mixture in a greased springform pan (26 cm Ø) and bake in a preheated oven (electric range: 175 °C/ convection oven: 150 °C/ gas: see manufacturer) on the lower rack for approx. 40 minutes. Approx. 15 minutes before the end of the baking time, place the cake on the upper rack. Remove from the oven and leave to cool on a cake rack for at least 3 hours. (After 3 hours the cake is still a little soft and cannot be cut as well. You can also prepare the cake the day before!) Whipped cream is delicious with it
waiting time approx. 3 hours
