Line a large baking sheet with parchment paper.
Combine the sifted flour, salt, and chopped pecans in a bowl.
Using a mixer, cream the butter until smooth. Add the powdered sugar and vanilla and mix to combine.
Add the flour mixture to the butter mixture and mix to combine. The dough will create a smooth and thick cookie dough.
Using a 2 Tbsp cookie scoop, scoop dough and then with your hands, roll to create a round ball and add to the baking sheet.
Repeat with all the dough, creating about 38-40 cookies, spacing about 1 inch apart from each other. Chill the cookie dough balls for at least 30 minutes.
Preheat the oven to 350℉ and then bake the chilled cookies for 14-15 minutes, or until slightly golden. The cookies should keep their round ball shape.
Remove from the oven and cool for about 5-10 until warm.
Roll the warm cookies in the powdered sugar, fully coating each cookie.
Place the coated cookies on a cooling rack and allow them to finish cooling.
Once the cookies are completely cool, coat the cookies in powdered sugar again.
Add to a platter or plate and serve.
