Step 1: Prepare the oven. Preheat it to 350 degrees.
Step 2: Cream the butter and powdered sugar in a stand mixer. Adjust the mixer speed to low, then add in the salt, vanilla, flour, and pecans.
Step 3: Into an inch ball, roll the batter and place the balls a few inches apart from each other on parchment-covered baking sheets. Place in the preheated oven and bake for about 11 minutes, making sure to keep an eye on the cookies to not overbake them.
Step 4: Take the cookies out of the oven when done and let them cool a little. Meanwhile, place a cup of powdered sugar in a large Ziploc bag or a wide bowl. Gently coat about 3 to 4 cookies at a time. Scoop the cookies using a fork, shaking gently to remove any excess powdered sugar. On cooling racks, transfer the cookies and let them cool completely before rolling each again in the powdered sugar.
