Pour cold cream into a large bowl, beat with sugar and vanilla sugar until stiff, then fold in the yogurt with a whisk.
Then roughly crumble the 4 meringues (meringues) and fold them into the cream and yoghurt mixture. Fold the frozen blueberries into the mixture and let everything stand for 1/2 hour in the refrigerator, then consume immediately.
The cream and yoghurt mixture freezes slightly due to the frozen fruit.
Also goes well with other berries, e.g. wild berry mix, raspberries, etc.
