Step 1: Preheat your oven to 180°C (350°F).
Step 2: In a large mixing bowl, cream together the softened butter and powdered sugar until light and fluffy.
Step 3: Add the egg yolks and vanilla paste, mixing until well combined.
Step 4: In a separate bowl, whisk together ground walnuts, flour, and salt. Gradually add this to the butter mixture until a soft dough forms.
Step 5: Roll small portions of dough into crescent shapes and place on a baking sheet lined with parchment paper.
Step 6: Bake for 15-20 minutes or until lightly golden. Watch closely to avoid over-baking.
Step 7: Cool on the baking sheet for a few minutes, then transfer to a cooling rack. Dust with powdered sugar once cooled.
