For the raspberry puree, boil 200 g frozen berries with jam sugar and 4 tbsp. orange juice. Cook for about 4 minutes while stirring until bubbly. Immediately pass through a sieve, stir in raspberry brandy. Let it cool down.
For the cream, mix mascarpone, yoghurt, sugar and 1⁄2 TL cinnamon with the whisks of the mixer. Whip cream until stiff and fold in.
Put about 75 g of frozen berries in a glass bowl. Spread a good half of the vanilla cream on top. Spread the rest of the berries, except for a few for decoration, on top. Add the raspberry puree. First cut the stollen into slices, then break into pieces.
Spread on the puree. Sprinkle with 2 tablespoons of orange juice. Add the rest of the mascarpone cream. Decorate with remaining berries for serving. Dust with icing sugar.
