Knead flour, quark, baking powder, milk, oil, salt and sugar with the dough hook of a hand mixer.
When everything is well kneaded, add the fried onions, cheese strips and ham cubes and knead.
Preheat the oven to 180°C. Line a baking tray with baking paper and form about 16 rolls from the dough.
Place the rolls on a baking tray covered with baking paper.
Put them into the hot oven and bake on the middle shelf for about 35 minutes. The rolls taste great plain or spread with cream cheese.
