Roast the hazelnuts in a pan without fat, take them out. Leave to cool. For the short pastry, put 225 g flour, hazelnuts, 75 g sugar, vanillin sugar, salt, 150 g butter and 1 egg into a mixing bowl and knead to a smooth dough with the dough hooks of the hand mixer. Roll out to a circle (approx. 32 cm Ø) on a floured work surface. Grease a springform pan (26 cm Ø). Carefully place the dough sheet into the tin with the help of the cake roll.
Pull up the rim approx. 3.5 cm and press on. Prick the base several times with a fork and chill in the tin for about 30 minutes. For the crumbles melt 100 g butter. Mix 150 g flour, 50 g sugar, cinnamon, butter and 1 pinch of salt with the dough hooks of the hand mixer to form crumbles and chill. Separate 3 eggs. Beat the egg white and 1 pinch of salt until stiff. Put the quark in a bowl. Mix in egg yolks, milk, 200 g sugar, lemon juice, pudding and sauce powder. Carefully fold in the beaten egg white. Pour the quark mixture into the mould. Spoon cranberries into the quark.
