Soft and chewy Chocolate Chip Cookie Bars recipe! Filled with mini chocolate chips, chocolate chunks, and walnuts.

In honor of National Chocolate Chip Cookie Day on August 4, I thought I’d post an easy and crowd-pleasing recipe that everyone should have. We all have a chocolate chip cookie recipe we love, but do you know what is even better than chocolate chip cookies? Chocolate Chip Cookie Bars full of chocolate, sugar, and walnuts.

Today, with these Chocolate Chip Cookie Bars, I have partnered with DoubleTree by Hilton in celebration of their new Cook(ie) Book, Start with Cookies. All opinions expressed below are completely my own.

Chocolate Chip Cookie Bar Recipe

For this chocolate chip cookie bar recipe, you’re going to want to gather up all of the regular ingredients you’d use for normal cookies. Plus a couple of special mix-ins. Here’s what you’ll need:

  • Butter – delicious fat to start these cookies off right.
  • Brown Sugar and Granulated Sugar – creamed with the butter, these are both used for sweetening and flavor.
  • Egg and Egg Yolks – these are both used for the structure and texture of the cookie bars.
  • Vanilla – for flavor.
  • All-Purpose Flour – to fill out the bars.
  • Baking Soda – the leavening agent.
  • Salt – to balance out all the sweetness.
  • Walnuts – chopped. You could also sub these out for a nut that you like.
  • Mini Chocolate Chips – I used semi-sweet mini chocolate chips.
  • Chocolate Chunks – buy storebought or a chocolate bar chopped up.

How to Make Chocolate Chip Cookie Bars

  1. Preheat oven to 350 degrees. Line glass 9×13 dish with parchment paper and set aside.
  2. Place butter into a large bowl and melt together in the microwave. Stir in brown sugar and granulated sugar until well combined.
  3. Add in egg, egg yolk and vanilla. Mix until lighter in color.
  4. Add in the flour, baking soda, and salt. Scrape the sides of the bowl and the bottom really well to ensure a smooth, well-stirred batter.
  5. Hand-stir the mini chocolate chips, chocolate chunks, and walnuts into the batter and press into prepared pan.
  6. Bake 15-18 minutes or until the center is mostly cooked.
  7. Cool 15 minutes before cutting into bars and serving.

You can definitely cut these when they’re warm (because warm cookies always win over room temperature cookies), but you run the risk of not getting perfect edges. If you’re not photographing them for your blog (ahem), then by all means, dig in immediately. Perhaps with some ice cream too.

    These cookies look amazing!! Can’t wait to try them! Just checking, but did you mean 3/4 cup butter? That would be 12Tbs, not 1 1/2 cups. Just want to make sure I have the right amounts! Thanks, Lauren!!

    The bars look great but they were a flop for me. I omitted the walnuts, due to our tastes, and used more chips instead. My 9×13 pan is not glass so I expected extra baking time. Even after 35 minutes, the bars are ridiculously soft and quite oily. I think the recipe needs more flour. A bit of a disappointment and I wouldn’t try this recipe again. Sorry, Lauren.

      I did have the wrong measurement for the butter when I first posted this recipe but corrected it a few hours later! That’s the only thing I could think of why they didn’t turn out! I’m so sorry you had a bad experience with one of my recipes!

        I did have the right butter amount but maybe the additional chocolate in lieu of walnuts really messed with it. It is not like we wasted them though, I found they were tasty as long as you ate them frozen 😉 which is perfect for a summer cookie.

      I made them and they were great! Baking them in a different pan and using more chocolate chips does change things (I know from experience) You should try them again in a glass baking dish and I’m sure you”ll love them!

        I am happy that these cookie bars worked for you! They definitely had good flavor even though they didn’t cook through for me so I am sure they were a hit with your son’s team.
        Unfortunately I don’t have a glass pan so I used my usual 9×13 and with other recipes, just adding baking time can usual account for the different pan material.
        In retrospect, I think that if I just left out the walnuts and didn’t increase the chocolate at all they might have been better!
