Preheat the oven to 350°F (175°C).

In a saucepan, melt the butter over medium heat until it begins to brown and has a nutty aroma. Remove from heat and let cool slightly.

In a mixing bowl, combine the browned butter, brown sugar, and granulated sugar until smooth.

Add the eggs and vanilla extract, mixing until well combined.

In another bowl, whisk together the flour, baking soda, and salt. Gradually add to the wet ingredients, mixing just until combined.

Fold in the chocolate chips and chopped pecans.

Drop spoonfuls of cookie dough onto a lined baking sheet.

Bake for 10-12 minutes or until the edges are golden.

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