This is very close to the "perfect" recipe I use from Tasty. But they add in a little bit of espresso powder. It's not enough to make the cookies taste like coffee, but it does make the chocolate flavor more intense. I really like this recipe, but now I want to try the ATK recipe and see which one is better because I swear by the Tasty recipe ever since I found it. Here it is if anyone's curious: https://tasty.co/recipe/tasty-101-ultimate-brown-butter-chocolate-chip-cookies
