Make the brown butter: Cut the butter in small pieces and heat the butter in a small pan on medium heat for about 3-5 minutes until the butter turns an amber color. The butter will first foam and start to pop. Then, brown bits will begin to form in the bottom of the pan. Once browned and popping slows, it is ready. You should smell a nutty aroma. Scrap the butter (and all the of those magical brown bits into a heat-safe bowl and let rest for about 15 minutes.

In a medium mixing bowl, sift the flour, baking soda, baking powder, and salt. Set aside.

In a large mixing bowl, and the cooled brown butter and white miso and mix until combined. Then, add the granulated sugar, light brown sugar, toasted sesame oil, and vanilla and beat with a hand mixer for 2 minutes.

Add the egg and yolk. Beat until well combined (about 30-60 seconds).

Add your "sifted flour mixture" into your wet batter and mix with a wooden spoon or rubber spatula until combined. Be sure not to over mix.

Fold in your chocolate.

Transfer the cookie dough to a fridge and let chill for at least 45 minutes to allow the flour to hydrate and obtain those beautiful flavors (Pro tip: Allowing your dough to refrigerate for at least 4 hours (or overnight) will result in the best flavored cookie; however, 45 minutes works just fine.)

Preheat your oven to 350°F. Line a nonstick baking sheet with parchment paper.

Remove your chilled dough from the refrigerator and using a medium (2 tablespoon sized) cookie scooper, scoop the cookie dough and roll the top of the cookies in the black and white sesame seeds. Then, place the dough on the lined parchment. The dough should be about 2 inches apart.

Bake the cookies at 350 degrees for 8-10 minutes or until the edges of the cookies are set and the center is soft. Use a cookie scoot to shape the cookies into the perfect circle. Then, top with flaky sea salt. Let rest for about 10-15 minutes or until set.
