These Milk Chocolate and Walnut NYC Style Chunky Cookies might just be my favourite thing right now. Thick, full of melty chocolate chunks and walnut pieces, perfectly gooey. These are for sure, my go-to cookie recipe when making for a crowd.

These cookies are a copycat of the Levain Bakery style. Recreate the flavours at home when you can’t make the trip. The dough freezes well, just make sure it comes down to fridge temp (at least) before baking. These are the best thing ever to eat warm when you need a bit of comfort food in your life. No chill time required either, making them a speedy bake!
The trick to nailing these is super cold butter and cornstarch (cornflour). These two things are crucial to a perfect cookie. For the double chocolate version, do check out my recipe! Also, the bake time is low, and the cookies may look a little wobbly. This is the desired outcome. Let the cookies rest up for several minutes before serving. The recipe makes about 10-12 cookies, depending on the size you’re going for. I tend to weigh my dough to keep them even, but of course, you don’t have to do this.
I bake these cookies on classic sheet pans (like these) and always opt for silicone baking mats (these are the ones I use) as they’re better for the planet!
