Mix butter, powdered sugar and vanilla thoroughly. Blend flour and salt and stir it into mixture. Mix in nuts, wrap in plastic wrap, and chill about an hour.
Heat oven to 400 degrees. (If I leave the dough in the refrigerator overnight, it gets really hard, so I zap it in the microwave for about 15 seconds, and it’s easier to work with.) Roll chilled dough into 1 inch balls, and place them on an ungreased cookie sheet.
Bake for 8 to 10 minutes and while warm, roll them in confectioners sugar. Let cookies cool and roll them in confectioners sugar again. Makes about 4 dozen.
