Preheat your oven to 350°F (175°C) and prepare your baking sheets with parchment paper.

In a large mixing bowl, cream the butter, brown sugar, and granulated sugar together until smooth and fluffy, about 2-3 minutes.

Beat in the eggs one at a time and add vanilla extract, mixing well.

In a separate bowl, whisk together flour, baking soda, and salt; gradually add to the wet ingredients, folding gently.

Fold in the chopped pecans evenly into the cookie dough.

In a separate bowl, whisk together corn syrup, granulated sugar, eggs, vanilla extract, and salt until smooth for the pecan filling.

Portion out cookie dough onto prepared baking sheets, leaving space between each scoop.

Create a small well in the center of each dough ball.

Fill each well with the pecan filling, being careful not to overfill.

Bake in the preheated oven for about 12-15 minutes until the edges are golden brown.

Let the cookies cool on the baking sheet for a few minutes before transferring to a wire rack.

Allow the cookies to cool completely before enjoying.
