Mash cottage cheese thoroughly with sugar. Add egg, sour cream, salt, baking powder. Mix everything well. Then add flour. Stir the curd dough thoroughly.
Divide the dough into 2 parts. Roll a sausage from each part. Cut the dough sausage into slices about 2 cm wide. Form curd cakes and roll them in flour.
Preheat a frying pan, pour in vegetable oil. Put the cheese cakes in hot oil. Fry syrniki over medium heat, first covered for 3-5 minutes, until golden brown on one side. Then turn the syrniki over to the other side and fry without a lid, also until golden brown, for another 2-3 minutes. The cheesecakes are ready!
