Brown the butter in a medium pan over medium heat. Stir the melted butter constantly. You will begin to notice the butter bubbling up. After a few minutes, you should start to smell a nice nutty flavor from the butter and little brown flecks at the bottom of the pan. These are the milk solids caramelized from the heat, which is what gives brown butter such a beautiful, complex flavor.

Remove the browned butter from the pan and allow the butter to solidify back to room temperature before making the cookies. (You can firm up the butter quicker by sticking it in the freezer for 10 minutes)

Once the butter is cooled to room temperature, add brown sugar and brown butter to your stand mixer. Cream together at medium speed for a couple of minutes.

Once the butter is cooled to room temperature, add brown sugar and brown butter to your stand mixer. Cream together at medium speed for a couple of minutes.

Add the flour, baking soda, baking powder, and salt in a separate bowl. Mix well until everything is evenly distributed.

Next, add the dry ingredients to the creamed butter and sugar. Mix on medium/low speed just until the flour is combined. Do not overmix the dough.

Lastly, fold in chocolate chips with a wooden spoon.

Chill your dough for at least 1-2 hours before baking. If you don’t have an hour to wait, ball your cookies and place the dough balls on your cookie sheet. Place the cookie sheet in the freezer for 20-30 minutes before baking.

Long Ferment Option: To long ferment, mix in the chocolate chips and place in the fridge for 12-24 hours before baking. This will allow the sourdough starter to develop a lovely flavor throughout the cookies.

Preheat the oven to 375 and place your cookie dough balls on a parchment-lined baking sheet.

Bake for 10-12 minutes or until the edges become brown and crisp. The middle of the cookie should still be soft and gooey-looking.

Let the cookies sit for 3-5 minutes to set up before removing them from the baking sheet. Once slightly cooled, top your cookies with flakey salt and enjoy!
