Add the pecans and maple syrup to a skillet over medium heat. Stir often until the pecans are toasted and the syrup thickens, about 5 minutes. Transfer to a cutting board, sprinkle lightly with flaky sea salt, and let cool.
To brown the butter, melt ½ cup butter in a skillet over medium heat, stirring often. As it foams, watch for the milk solids to turn golden brown and smell nutty. Once browned, immediately transfer to a glass bowl and let cool for about 5 minutes.
Cream the cooled brown butter, remaining ½ cup softened butter, and both sugars together. Mix in the eggs and vanilla.
Add the flour and baking soda, stirring just until combined.
Fold in the candied pecans and semi-sweet chocolate chips until evenly distributed.
Using a tablespoon scoop, portion the dough onto a parchment-lined baking sheet. Lightly flatten the tops with your hand or spoon.
Bake for 10 minutes, until the edges are lightly golden and the centers still look soft. Let cool on the baking sheet for 5 minutes before serving.
Enjoy!
Notes
Make sure to let the cookie cool on the baking sheet for the full 5 minutes. They will continue to cook just a tad and will be perfect after a few minutes of rest.
