Grandma’s cherry sour cream sheet cake

With the 625 ml milk (note: do not use the amount of milk stated on the package!)

and prepare a pudding using the 2 packets of pudding powder according to the instructions on the packet (with sugar, see packet).

When the mixed pudding powder is added to the milk, stir a lot and it will thicken straight away. Allow to cool slightly, but not for too long, otherwise there will be lumps in the mixture. Stir in the sour cream and egg yolk and spread over the base. Spread the sour cherries (reserve the juice!) over the mixture and bake again at 180 °C top and bottom heat for 15 minutes.
