For the filling with the cherry juice, custard and sugar, cook a custard. Then add the cherries and the alcohol.
Now pour the mixture onto the base, which has meanwhile been flattened out on a baking sheet.
Now make the crumble from butter, sugar, flour and almonds and spread on the cherry filling.
Now bake the cake: 50-60 minutes 180 ° C hot air, 200 ° C top-bottom heat.
Let it cool on the baking sheet, as it is very juicy. You can also bake the cake the day before and only put the whipped cream on it the next day, then it is really cold. Sweeten the cream as required. Sprinkle cocoa or chocolate shavings on top of the cream.
