Thick and Chewy Chocolate Chunk Cookies

Chunky with crunchy walnuts, chewy with oats, fudgy with chocolate, these bake into thick, craggy disks with crisp edges and tender centers. Chopping the chocolate by hand gives you the obvious joy of big melty chunks, but, as importantly, slivers as thin as splinters that season the dough throughout. Untoasted whole walnuts have a tannic edge to their nuttiness that balances chocolate's richness while highlighting its bittersweet side. And oats — lots of them — add a nuanced natural earthy sweetness to the white-and-brown sugar base. Each bite gives you everything at once and also something new. You might hit a motherlode of chocolate or a walnut's crackle, but always with the foundational oatmeal chew of a nicely salted buttery cookie.
