Wash the strawberries and cut into bite-sized pieces.
Put the cookies in a freezer bag and crumble them with a meat mallet or rolling pin depending on the size you want.
For the cream, whip the cream until stiff, use cream stabilizer if necessary. Mix the mascarpone, yoghurt and low-fat quark and vanilla sugar with a whisk or hand mixer and fold in the cream. How much sugar is needed depends on the sweetness of the strawberries and their own taste.
Now it is layered: First the strawberries, then a layer of cream and then the crumbled cookies. I always do 2 shifts.
The individual components of the dessert can be prepared a day in advance, but should be layered shortly beforehand, otherwise it will become soggy.
If there are no fresh strawberries, I also like to take grapes, they taste great too.
