Using an electric mixer or a spoon, cream together the butter, sugar, and vanilla.
Next, stir in the flour, salt, and cinnamon.
Add in the pecans, cover, and chill for 30 minutes.
Scoop 1 tbsp of dough to form 1 inch rounds. Space about 1 inch apart on baking sheet.
Bake in a preheated 375°F oven until bottoms are golden and tops are just beginning to brown- about 16-18 minutes.
Remove from oven and cool for 5 minutes, then roll to coat in powdered sugar.
Then allow cookies to cool completely. Some of the sugar may melt as the cookies cool. Toss and coat a second time.
