For the muffin batter, stir the butter and sugar until creamy. Gradually stir in the eggs. Stir in the juice. Mix in the flour, baking powder, salt and orange peel and stir in. Pour the batter into the muffin molds and put 2 - 3 mandarin fillets in each muffin mold. Bake at 170 ° C for about 25 minutes.
For the topping, mix the quark with the vanilla sugar and whip the cream until stiff. Fold in the cream. Pour the topping onto the cold muffins with a piping nozzle and decorate with tangerine fillets, white chocolate and orange zest.
Tip: Take the muffins out of the oven five minutes before the end of the baking time, let them cool and freeze. If necessary, bake for 10 minutes in the preheated oven, do not defrost beforehand.
