Select the berries, possibly wash and clean them. For the dough mix eggs, 200 g sugar, vanilla sugar, 200 g very soft butter and yoghurt. Mix flour and baking powder and stir in.
Spread the dough on a greased and floured baking tray (35 x 40 cm). Spread the berries on top. Bake in a hot oven (electric cooker: 200 °C/circulating air: 180 °C/gas: see manufacturer) for approx. 25 minutes.
For the nut crumbles, mix 50 g butter, 4 tablespoons sugar and almonds with your hands until crumbly. About 5 minutes before the end of the baking time, spread the nut crumbles on the cake and bake. Let the finished cake cool down on a cake rack.
