Directions:

Preheat oven to 400 degrees.
Cream together the butter, sugar and vanilla.
Slowly add the flour and salt and mix just until combined.
Stir in the nuts.
Scoop into 1-inch balls and place on cookie sheet.
Bake 10-12 minutes, until cookies are set but not browned.
Remove from the oven and allow the cookies to cool on the tray for a minute or two and then roll each warm cookie in powdered sugar and set them on a cooling rack.
After cooled, roll again in powdered sugar.
