For the cheesecake with peaches, knead flour, baking powder, 85g sugar, salt, 1 egg and cold pieces of butter. Wrap in plastic wrap, refrigerate for about 30 minutes.
Drain peaches and cut into small pieces. Preheat oven to 180°C (top and bottom heat) (convection oven: 160°C).
Separate remaining eggs. Mix egg yolks, curd, 160g sugar, custard powder, oil, milk, lemon juice. Fold in the peaches.
Roll out the dough into a round shape and place it in a greased springform pan (26 cm diameter), covering the edges with the dough as well.
Pour the cream into the pan and bake the cake on the middle shelf for about 60 minutes.
Beat egg whites and remaining sugar (100g) until stiff, spread on cake after 60 minutes baking time. Bake for another 10-15 minutes (until the snow is lightly browned). Let the cheesecake with peaches cool and serve.
