Cottage Cheese Vatrushki with Cherry

Thaw the cherries and drain excess liquid. Add sugar and cornstarch, then gently toss to combine.

In a large bowl, combine the cottage cheese, eggs, sugar, vanilla sugar, salt, and melted butter. Mix until smooth.

Add the flour and baking powder, and knead into a soft dough. It should be pliable and slightly sticky.

Divide the dough into 8 or 10 equal portions. Shape them into balls and place them on a baking sheet lined with parchment paper.

Make an indentation in the center of each ball using the bottom of a glass or your hands. Fill the cavity with the cherry filling.

Whisk together the egg yolk and milk, then brush the edges of the vatrushki.
