Mega creamy 10-minute quark cheesecake with mandarins without a base

First, place the mandarin oranges in a colander and let them drain. Preheat the oven to 180 degrees Celsius (350 degrees Fahrenheit) top/bottom heat.
Add the quark, cream cheese, Greek yogurt, crème fraîche

and the juice of half a lemon and mix on low speed until creamy. Stir in the sugar until it no longer crunches.
Add the vanilla pudding mix and mix in. Finally, briefly beat in the eggs, one at a time.
Pour the cheesecake mixture into a baking dish, top with the mandarin oranges, and bake the cake in the oven for 60-75 minutes, until the center of the cake is only slightly wobbly.
After the baking time is over, let the cake cool slowly by placing a potholder over the oven door.
