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

In a large mixing bowl, cream together butter, brown sugar, and granulated sugar with an electric mixer for 2-3 minutes until smooth.

Add eggs one at a time mixing well after each. Then mix in vanilla extract until fully combined.

In a separate bowl, whisk together flour, baking soda, and salt. Gradually fold into wet ingredients until just combined.

Fold in chopped pecans carefully to maintain their texture.

For the filling, whisk together corn syrup, sugar, eggs, vanilla extract, and a pinch of salt in another bowl until smooth.

Scoop dough onto prepared sheets, creating wells with your thumb.

Fill each well with the pecan filling mixture.

Bake for 12-15 minutes until edges are golden and centers are soft.

Allow cookies to cool on baking sheets for 5 minutes before transferring to a wire rack.
