Cream butter, sugar, vanilla and salt together in bowl. You have the option of toasting your walnuts until golden brown, but let them cool.

Place the walnuts in a food processor or blender and crush until fine. Add this mixture to the butter, sugar, and salt.

Add the flour slowly to the mixture and mix until combined.

Wrap the dough in seran wrap and put it in the fridge for 1-2 hours to chill.

After chilled, preheat oven to 325 degrees. Drop the dough by small scoops onto parchment lined cookie sheets.

Bake for 10 minutes. Take them out and let them cool on a cooling rack. Once cooled, roll them in the powdered sugar. Enjoy!
