Pour the cherries into a sieve and collect the juice. Measure 100 ml cherry juice. Boil up 2 tablespoons of sugar, cherry juice, to 2 tablespoons. Stir the remaining 2 tbsp. juice and vanilla custard powder until smooth and bind the juice with it.
Add the cherries, fold in and allow to cool.
Chopping chocolate. Knead the flour, 150 g sugar, cocoa, approx. 2/3 of the chocolate, peanut cream and margarine into crumbles. Cut baking paper into 12 squares of approx. 12 x 12 cm. Line the hollows of a muffin tray with the baking paper.
Spread about half of the crumbles in the bowls, press lightly, pressing one bowl at a time. Spread cherries in it. Coarsely chop the peanuts. Knead the remaining crumbles and peanuts and spread on the muffins.
Bake in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: see manufacturer) for approx. 30 minutes. Sprinkle the muffins with the remaining chocolate, allow to cool and remove from the trays.
