Stir pudding powder, 4 tablespoons of sugar and 5 tablespoons of milk until smooth. Bring 400 ml milk to the boil. Stir in the pudding powder, then simmer for about 1 minute while stirring. Cover surface with foil and chill. Put the cherries in a sieve and let them drip off. Stir fat, 300 g sugar and salt until creamy. Stir in eggs one at a time, alternating with 4-5 tablespoons of flour.
Mix remaining flour and baking powder and add alternately with lemon juice and sour cream to the fat egg mixture. Mix everything to a smooth dough. Pour the dough into the greased, floured fat pan of the oven (approx. 41 x 32 cm) and smooth it down. Stir the pudding until smooth and spread on the cake by the spoonful. Spread cherries on top and bake in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for 25-35 minutes. Remove the cake from the oven, let it cool down and dust with icing sugar before serving
