Prepare ingredients for the recipe. You can use any cottage cheese brand you have on hand.
Combine together cottage cheese, sugar, eggs and vanilla extract. You can use a blender for it or a food processor.
In a small bowl, combine baking soda with vinegar, add it into the mixture. Also add baking powder and flour to the mixture.
You will end up with very sticky dough, so flour the work area really well. Divide the dough into equal pieces.
Form round shapes out of each piece, placing them apart on a baking sheet. Bake at 350F buns for 12 minutes, than apply some milk with pastry brush and sprinkle some sugar on top.
Continue baking them for another 5-10 minutes or until they are golden brown. Let them cool to a room temperature and they are ready to be served. To keep them fresh, have them sealed in an air tight container.
