Mix the mascarpone, quark, milk and vanilla sugar together. Melt the butter in the pan, add the sugar and toast the almond flakes in it. Cut the meringue into pieces (not too small, there shouldn`t be any crumbs!).
Now layer the mascarpone cream, frozen raspberries and meringue pieces alternately in a bowl. Start with the mascarpone cream, then raspberries, then meringue, then mascarpone cream, raspberries
Place the bowl in the refrigerator for 3-4 hours and let it steep.
