SOUR CREAM PASTRY ROLLS

Cut the cold butter into the flour. Rub it in with your hands, then add the baking soda and vanilla sugar.

Make a well in the center, add the eggs and sour cream, and mix with a fork. Knead into a dough (feel free to add a bit more flour if needed).

For the filling: rub the flour into the cold butter. Add the sugar and vanilla sugar, and mix well.

Divide the dough into 3 parts. Roll out each part to about 3 mm thick and evenly top with the filling.

Roll up tightly into logs and slice into small pieces.

Line a baking sheet with parchment paper and arrange the rolls on it.

Brush the tops with an egg yolk beaten with a little milk.
