Dark Chocolate Chunk Cookies are the perfect soft and chewy cookie, using chopped dark chocolate and a secret ingredient – cornstarch! Three teaspoons of cornstarch was the magic number for this recipe, after several rounds of testing. Cookies anyone? 🙂

This isn’t just any old chocolate chip recipe. It is the BEST recipe. I’ve been playing around with it for the last couple of weeks, sending cookies to friends and neighbors at every turn.

Goals for epic cookies:

  • I wanted the cookie to LOOK a certain way – round, slightly puffy, sturdy, and golden. Check.
  • I also wanted it to TASTE buttery, creamy, and slightly salty. Check.
  • Lastly, I wanted the PICTURES to be perfect. This actually took two shoots because I rushed the first time and didn’t get them right. So finally…Check.

After trying store-brand chocolate chunks, I decided to step it up to this premium quality Ghirardelli brand. It actually makes me think of our San Francisco trip and the little Ghirardelli shop INSIDE our hotel. (Trouble with a capital T!)

This dark chocolate is the bomb. So decadent, and chopping your own makes the cookies look more unique. I used two 4 ounce bars for my recipe.

Have you ever made cookies that got flatter than a pancake and literally baked into each other?¿ ME!! My hand is UP!

Tips for battling this flat-pancake-messy-cookie-baking scenario.

  1. ALWAYS refrigerate your dough for at least two hours before baking. I usually make the dough the day before I bake  – so I refrigerate overnight.
  2. Bake the first cookie ALL BY ITSELF, so you can adjust the flour accordingly. My momma taught me this and you can see some of her recipes here.
  3. Use cornstarch (<— SECRET ingredient) in your cookies to give them a little extra poof. Mike’s grandmother (Grandma Helen) used cornstarch in her cookies, and they were always perfectly round and thick.

Testing this recipe involved four batches. That’s a lot of cookies for a family of four (and Josh left for college during testing). But I made a huge mistake between batch three and four. I gave most of #3 away and realized that I had only photographed the cookies in a stack (not even pictured here). I’ve gotten pretty fussy with my photography, so I whipped up batch #4 and took the additional pictures I needed.

Needless to say, Dark Chocolate Chunk Cookies have been flying out of here by the plateful. I’m glad I have self-restraint…but enough is enough. Pass the veggies please! 🙂
