Put it into a greased and flour-spread springform pan (24 cm Ø). Press the rim evenly. Roll out remaining dough to a circle (24 cm Ø).
Put both in a cool place. Caramelise 300 g sugar for the filling. Add nuts and stir in. Add cream, bring to the boil and dissolve the caramel while stirring. Put the nut caramel into the mould.

Turn down the oven (electric oven: 150 °C/ convection oven: 125 °C/ gas: level 1) and continue baking for about 15 minutes. Remove the cake from the oven and put it in the tin, preferably overnight.
