A wonderful, thin and crispy chocolate chunk cookie with chewy middles and the loveliest subtle pumpkin spice flavor. Like a chocolate chip cookie, all dressed up for sweater weather. The pan-banging method for flattening out the cookies comes from the wonderful Sarah Kieffer. NOTE: You’ll want to make the brown butter a little in advance here, so it has the chance to re-solidify in the fridge. Once that’s happened, the cookies come together quickly.Â
