Salted Butter and Chocolate Chunk Shortbread

There is a cookie craze online for this recipe from Alison Roman's Dining In—read more about it here. Roman writes: “Less chocolate chip cookie, more brown sugar shortbread with chocolate chunks—they just might be the cookie you’ve been looking for. Made with lots of salted butter (it has a slightly different flavor and a deeper saltiness than using just salt), the dough has just enough flour to hold it together and the right amount of light brown sugar to suggest a chocolate chip cookie. If you find it tragically annoying to buy salted butter just for this recipe, you can use unsalted butter and add ¾ teaspoon kosher salt to the flour.”
