Preheat oven to 400°F (204°C)
In a large mixing bowl, beat the 1 cup room temperature butter and ½ cup sugar until light and fluffy.
Add the 2 teaspoon vanilla extract and ½ teaspoon salt and beat until combined.
Remove the bowl from the mixer and with a wooden spoon, fold the 2 ¼ cups of all-purpose flour until combined.
Fold in the ¾ cup chopped pecans into the cookie dough until evenly combined and scoop out liberal tablespoons of cookie dough and roll into balls.
Place evenly, spaced a ½ inch apart, on a cookie sheet and bake for approximately 12 minutes, or until firm to the touch.
Cool completely on a wire rack and then roll in powdered sugar.
