Preheat the oven to 350°F (175°C).
In a large bowl, cream together the softened butter, brown sugar, and granulated sugar until light and fluffy.
Beat in the eggs one at a time, followed by the vanilla extract.
In a separate bowl, combine the flour, baking soda, and salt.
Gradually add the dry ingredients to the wet mixture, mixing until just combined.
Fold in the chopped pecans.
Scoop tablespoon-sized portions of dough onto a baking sheet lined with parchment paper.
Press a whole pecan into the center of each cookie.
Bake for 12-15 minutes, or until the edges are lightly golden.
Allow to cool on the baking sheet for a few minutes before transferring to a wire rack to cool completely.
