In a deep bowl, mix cottage cheese, egg yolk, flour, powdered sugar, salt and vanilla until smooth. Form round balls weighing approximately 50–60 g from the resulting mass and shape into small cakes.
Roll each cheesecake in flour, fry in melted butter on both sides until golden brown.
Transfer the cheesecakes to a refractory form and place in the oven for 2-3 minutes, preheated to a temperature of 180 degrees.
Serve ready-made syrniki with vanillin with jam, sour cream or condensed milk.
