Mash the egg, sugar, and cottage cheese together and whisk. Sift in the flour with the salt and baking powder, and knead by hand into a dough. Gather into a ball and let it rest for 15 minutes.
Roll the dough out thinly into a rectangular sheet, cut it into strips with a knife, and twist each strip into a ring (you can also just leave it as a strip).
If you like, sprinkle with poppy seeds, sesame seeds, or nuts. Place on a baking tray greased with vegetable oil and bake for 20 minutes at 180°C, flipping halfway through.
Let the finished cookies cool completely. Enjoy!
