Preheat the oven to 350°F (175°C) and line two baking sheets with parchment paper.
In a large mixing bowl, cream together the softened butter, brown sugar, and granulated sugar until light and fluffy.
Beat in the eggs one at a time, then mix in the vanilla extract.
In another bowl, whisk together the flour, baking soda, and salt. Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
Fold in the chopped pecans and mini chocolate chips if using.
In a small saucepan over low heat, combine the corn syrup and remaining half of the chopped pecans, stirring until the mixture is warm and well combined.
Scoop tablespoon-sized balls of cookie dough onto the prepared baking sheets, spacing them about 2 inches apart.
Using a teaspoon, make a small indentation in the center of each cookie and drizzle a small amount of the pecan-corn syrup mixture into the indentation.
Bake for 10-12 minutes or until the edges are lightly golden.
Allow the cookies to cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely.
Notes
Dust the cooled cookies with powdered sugar and serve them on a decorative platter, garnished with whole pecans for an elegant touch.
