Drain the peach halves in a sieve. Cut the halves into columns. Put flour, butter in flakes, 200 g sugar, salt, vanillin sugar and egg in a large mixing bowl. First use the dough hooks of the hand mixer, then work into crumbles with your hands
Spread a good 2/3 of the crumbles on a greased, flour-dusted baking tray, press them to a base with your hands. Spread peach slices on one half of the base and cranberry compote on the other half. Sprinkle the remaining crumbles and almond flakes on top
Bake the cake in the preheated oven (electric oven: 175 °C/ convection oven: 150 °C/ gas: see manufacturer) on the bottom shelf for 35-45 minutes. Take out, let cool down a little. Halve the warm cake between the two toppings. Cut the peach cake on the tray into 18 pieces. Leave to cool on the tray
Whip the cream until stiff, adding 1 sachet of cream firming agent and 75 g sugar. Stir the sour cream and 1 sachet of cream firming agent until smooth. Fold the cream into the sour cream. Place the cranberry cake on a board, possibly enclose it in a baking frame. Spread the cream on the base. Place the peach cake cut into pieces on top. Chill for about 2 hours.
