Mix the sugar, flour, vanilla sugar and baking powder well. Then stir in the quark and eggs well. And so well until a solid and sticky mass is formed.
Heat the deep fat fryer to 160 ° C. Now shape the dough into appropriate balls with two tablespoons and place them in the preheated deep fryer and fry them, turning constantly, until they are golden brown. Remove and drain. Then sprinkle with powdered sugar or sugar, depending on your taste.
Tip: dip the two tablespoons briefly in the hot deep fryer beforehand so that the donuts can be processed better.
