Line a baking sheet with parchment paper and preheat the oven to 350F. Next, remove the dough from the fridge and use a 3-tablespoon cookie scoop to form your cookie dough (about 50 grams of dough per cookie).
Roll the cookie dough into balls between your palms and then roll each in the 2 tablespoon of sugar that was set aside so that each dough ball is coated in sugar.
Place the black sesame cookie dough balls onto the baking sheet. Make sure that each cookie is kept about 2 inches apart since they will spread slightly while baking.
Bake for 12-14 minutes until the cookie bottoms are lightly browned and the cookies are cooked through but still have soft centers. The cookies will continue baking after they are removed from the oven so the centers should be soft and slightly under-cooked, but not glossy or raw, when they are removed from the oven.
Remove the cookie tray from the oven and immediately tap the tray on the counter to produce a more “wrinkly” cookie. You can also swirl the cookies between a mug or use a spoon to shape them into perfect circles.
Then, let the cookies cool on the baking sheet for 5 minutes. Once the black sesame cookies have cooled, serve and enjoy!
