Drain the cherries and collect the juice. Bring 200 ml of juice to a boil in a saucepan. Mix the vanilla pudding powder with 2 tablespoons of cherry juice and 1 tablespoon of cinnamon sugar and add to the boiling cherry juice. Stir. Add the drained cherries and remove the pan from the heat.
Now mix the milk, eggs, vanilla sugar and the remaining sugar together. Halve the milk rolls and dip in the egg mixture. Now fry the rolls in a hot pan with butter until golden brown. The morello cherries are served as a side dish (sauce).
