2In a large bowl, combine the cottage cheese, flour, eggs, sugar, baking powder, and vanilla extract. Mix well until you get a smooth dough.
Divide the dough into small portions and shape them into balls. Flatten each ball slightly and make a small hole in the center to form a doughnut shape.
Heat oil in a deep frying pan over medium heat. Fry the doughnuts until they are golden brown on both sides. Remove them from the oil and place them on paper towels to drain excess oil.
Serve the papanasi warm, topped with sour cream and cherry jam.
