Preheat oven to 375℉.
In medium bowl, whisk together the flour, salt, and baking soda. Set aside.
Melt 12 tablespoons (reserving 4 tablespoons) of butter in a medium saucepan over medium heat, stirring constantly.
Increase the heat to medium-high and continue to stir until the butter becomes a light golden brown color and develops a nutty aroma.
Remove from heat and add the remaining 4 tablespoons butter. Continue to stir until the remaining butter has melted.
Add the brown sugar and granulated sugar. Stir until well incorporated.
Add vanilla, eggs and sourdough discard. Stir until smooth.
Slowly add the flour mixture and mix until completely combined and starting to pull away from sides of bowl.
Stir in the chocolate chips.
Scoop 1½ in sized cookie dough balls onto a baking sheet lined with parchment paper, spacing at least 2½ inches apart. Store the remaining cookie dough in the fridge, covered in plastic wrap, to chill in between batches.
Bake for 12-15 minutes. The cookies should appear slightly golden and puffy when done.
Allow to cool 5 minutes in pan before transferring to a wire rack to cool completely.
