Instructions
Step 1 – Prepare the Dough
- Combine the flour and salt in a large bowl.
- Cut in the cold butter until the mixture resembles coarse crumbs.
- Mix in the sour cream, egg yolk, sugar, and vanilla.
- Knead briefly until a smooth dough forms.
- Wrap the dough and chill for 1 hour.
Step 2 – Make the Filling
- Mix the ground walnuts, sugar, cinnamon, vanilla, and lemon zest.
- Add the milk a little at a time until the filling is moist but firm enough to shape.
Step 3 – Shape the Crescents
- Preheat the oven to 180°C (350°F).
- Roll the dough to about 3 mm (⅛ inch) thick.
- Cut into triangles (about 8–10 cm / 3–4 inches wide).
- Place a spoonful of walnut filling on the wide end.
- Roll toward the tip and gently curve into a crescent.
Step 4 – Bake
- Arrange the cookies on a parchment-lined baking sheet.
- Bake for 18–20 minutes, until the edges are lightly golden.
- Cool on a wire rack.
Step 5 – Finish
Dust generously with powdered sugar before serving.
Tips
- The dough should stay cold while working for the flakiest texture.
- Ground poppy seeds can replace the walnuts for a traditional variation.
- Store in an airtight container for up to 1 week.
- These cookies freeze well for up to 3 months.
