Brown butter, buckwheat and espresso come together to create a deep rich cookie that you can sink you teeth into. These cookies bake into large round cookies that are flat, chewy and rich with warm nutty buckwheat notes. To intensify that nuttiness, browned butter is added for more depth and warmth to the cookie. A hefty spoon of espresso powder is added to create another dimension of flavor. But the real key to a stellar chocolate chip cookie? Using high quality chocolate! This cookie dough gets a whole bar of 70% chocolate added to it. The freshly cut deep dark chocolate chunks pair beautifully with this cookie and turn into these gorgeous puddles of chocolate. This cookie would not be complete without a showering of flaky salt.
