For the filling, combine the cottage cheese with the powdered sugar and mix well.

Knead the yeast dough and divide it into portions right away.

Stretch each portion into a rectangle and spoon the cottage cheese filling onto the center. Cut slits along the sides and braid them together.

Transfer the buns to a baking sheet and let them proof in a warm spot.

Brush the proofed buns with beaten egg and bake for 20-25 minutes in an oven preheated to 180-200°C.

Let the finished vatrushki cool. Enjoy!
