In a mixing bowl, combine 2 cups all-purpose flour and 1 teaspoon kosher salt. Set aside.
In a large bowl, cream together 1 cup (2 sticks) of softened unsalted butter, 2 teaspoons of pure vanilla extract, and ½ cup of powdered sugar using a hand or stand mixer on low speed.
Slowly fold in the dry ingredients, a little at a time, and mix at low to medium speed. Add 1 cup of chopped pecans and mix just until combined. Do not overmix.
Cover and refrigerate for at least one hour for the best results.
Preheat the oven to 350°F and remove the dough from the refrigerator.
Roll into 1 inch balls and place on a parchment-lined cookie sheet. Using a small cookie scoop helps to keep the cookies uniform in size. Try to handle the dough as minimally as possible for the best results.
Place in the oven and bake 12 - 15 minutes or until the bottom of the cookie is golden brown.
While cookies are baking, prepare a shallow bowl or baking dish with 2 cups of powdered sugar.
When cookies are done, immediately roll warm cookies in the powdered sugar. Ensure your cookie is fully covered with powdered sugar and set aside to cool. Using a sifter, dust the cookies with additional powdered sugar.
Serve and ENJOY!
