In the bowl of a stand mixer add butter and granulated sugar.

Beat on medium speed until creamed and light and fluffy in texture.

Add the flour, chopped nuts, vanilla extract, and kosher salt.

Mix until combined. Making sure to scrape the sides occasionally to get all the ingredients incorporated.

Roll the dough and cover with plastic wrap and place it in the refrigerator for 30 minutes. 

When ready to bake, remove the cookie dough from the refrigerator.

Preheat your oven to 350 degrees F and line two baking trays with parchment paper. 

Scoop the mixture and roll it firmly into a ball of dough. Place on the baking tray. 

Bake for 25 - 30 minutes until slightly golden. 

Remove from the oven and let them cool for a minute or two. Roll them in the powdered sugar until completely covered and set them on a rack to cool completely. 

If you want them really white, roll them in the sugar for a second coating once they are completely cool.
