Mix the water, eggs, sugar and vanilla sugar until frothy. Fold in the flour mixed with baking powder. Spread evenly on a baking sheet lined with baking paper. Bake at 220 ° C for about 10 minutes.
Boil pudding with cherry juice. Spread the cooled pudding cream on the cooled cake batter.
Let the cake stand in the refrigerator overnight so that the custard cream sets properly.
Tip:
You can also take a glass of cherries and fill the juice from the glass up to a liter with cherry juice. After the pudding has cooked, fold in the cherries and then pour the mixture on the bottom.
