Preheat oven to 350 degrees.
In a mixing bowl, cream together:
1/2 cup soft butter
1 cup powdered sugar
1 tsp. vanilla
1 cup flour
1 cup chopped, toasted pecans (before making cookies, bake pecan halves for 8-10 min. @350... cool & chop up)
Form cookies in 3/4" balls, place on ungreased sheets, leaving a little bit of space (but these cookies don't spread out). Flatten them slightly. Bake for 12-14 minutes, until the edges are golden.
While still warm, put a cup of powdered sugar in a bowl & gently toss warm cookies in the powdered sugar. Cool.
