Right along with politics and the most effective way to load a dishwasher, defining the perfect chocolate chip cookie is guaranteed to spark a debate. The winning argument: chewy Chocolate Chip Walnut Cookies!

Chocolate chip cookies are a source of (mostly) good-spirited debate in our household.

Which is the greatest chocolate chip cookie?

  • Is it chewy or crispy?
  • Fluffy or flat?
  • Nuts or no nuts?
  • Dark chocolate or milk chocolate?

Though I know you are narrating a declarative answer to each of these questions in your head, today I’m excited to tell you about my second favorite chocolate chip cookie of all time: chocolate chip walnut cookies.

They are:

  • Gratifyingly chewy
  • Not too thick and not too thin
  • Punctuated with toasty walnuts (you’ll like ’em!)
  • Dark chocolate is the only chocolate that has business in my cookie dough

The World’s Best Chocolate Chip Walnut Cookies

Wondering where my favorite chocolate chip cookie recipe of all time can be found? My cookbook!

Those cookies are the world’s best and worth a copy alone. YES, I SAID IT.

While I am no stranger to gussying up a chocolate chip cookie (Banana Oatmeal Cookies with chocolate chips, Zucchini Cookies with chocolate chips, and Healthy Peanut Butter Oatmeal Cookies are three faves) or doubling up on the chocolate (hello, Dark Chocolate Cookies), I adore classic chocolate chip cookies with all of my heart.

If you are a fan of soft, chewy cookies made with more nutritious ingredients, you’ll fall for them too!

5 Star Review

“These are our new favorite chocolate chip cookie, by far. We cannot keep enough on hand. SO delicious and they keep really well and stay chewy for literally weeks. They’re the current favorite dessert in our household, and I have made them several times now!”

How to Make Chewy Chocolate Chip Walnut Cookies

This recipe for oatmeal chocolate chip walnut cookies is inspired by the thick, chewy DoubleTree Hotel chocolate chip oatmeal cookies (if you’ve stayed at a DoubleTree, you know the ones).

I revamped the original recipe to suit my ideal cookie preferences.

  • They are ooey-gooey (sorry thin, crispy cookie-lovers; these are for my fellow chewy fans).
  • Use all butter (key for the fullest flavor).
  • Have more brown sugar than white (for extra softness).
  • As with my full lineup of healthy cookie recipes, I used whole grains, without sacrificing taste or an ounce of cookie softness.
Whole Wheat Walnut Chocolate Chip Cookies. My PERFECT chocolate chip cookie recipe.

The Ingredients

  • Oats + Flour. Regular readers know I’m a serious advocate for incorporating whole grains wherever possible, but never at the expense of taste. These cookies are 100% whole grain, thanks to a combination of ground oats, which give the cookies extra body and chewiness (think the DoubleTree Hotel cookie) and white whole wheat flour.
  • Butter. We’re going all in with the butter in this recipe. It’s critical for achieving the perfect flavor and texture. (Prefer a chocolate chip cookie made without butter? Check out my Healthy Chocolate Chip Cookies or Healthy Oatmeal Cookies.)
  • Dark Brown Sugar. Makes our cookies deliciously sweet, moist, and chewy.
  • Espresso. Though you can’t taste the coffee flavor in the cookies, the espresso intensifies the chocolate flavor (as these Brownie Cookies prove). It is magical and well worth trying!
  • Cinnamon. A pinch for extra warmth. It’s subtle, but completely delectable and adds another dimension of flavor.
  • Vanilla. Vanilla anchors the chocolate and espresso, so no imitators please! We are baking cookies from scratch, so let’s use real, pure vanilla extract and do them justice shall we?
  • Apple Cider Vinegar. This ingredient sounds odd, but trust. It keeps the cookies from being too sweet and tempers the taste of the whole grains.
  • Dark Chocolate Chips. Good quality chocolate chips are very important to creating the best-possible chocolate chip cookie. After all, what’s a chocolate chip cookie without the melt-in-your-mouth chocolatey goodness? Want more? This Cookie Cake will be perfect.
  • Walnuts. Old fashioned chocolate chip cookies with walnuts are a classic for a reason. Finely chopped, walnuts add an extra richness and toastiness to the cookies without overpowering them.

Substitution Tip!

No walnuts? You can swap them for finely chopped toasted pecans, cashews, or an additional 1/4 cup of chocolate chips.

The Directions

Dry ingredients in a food processor
  1. Grind the oats. Mix them with the flour in a bowl.
Wet ingredients in a bowl
  1. Beat the butter, sugars, vanilla, espresso, cinnamon, and salt together.
Cookie batter in a bowl
  1. Add the baking soda, vinegar, and egg.

Chilling Cookie Dough

For cookies with a richer flavor and that won’t spread on the baking sheet, YES you need to chill the dough.

  • Allowing the dough to chill overnight in the fridge gives the flavors time to get friendly, allows the wet and dry ingredients to fully incorporate, and results in a cookie of superior taste and texture.

Storage Tips

  • To Store. Leftover cookies will keep in an airtight storage container at room temperature for up to 1 week.
  • To Freeze. Freeze baked cookies in an airtight freezer-safe storage container or ziptop bag for up to 3 months. Thaw and enjoy as desired.

Meal Prep Tip

You can prepare the cookie dough in advance and freeze it for easy cookies on demand. This is ideal for last-minute entertaining (or late-night “emergencies”).

  • Prepare the cookie dough, and drop it as directed onto two parchment-lined baking sheets. Freeze until solid.
  • Transfer the frozen cookie dough balls to an airtight freezer-safe storage container or ziptop bag.
  • Bake directly from frozen on demand, adding a few extra minutes to the baking time.

What to Serve with Chocolate Chip Cookies

OK, now that I’ve given you the full spectrum of what makes these chocolate chip walnut cookies my idea of the perfect chocolate chip cookie, here is what you actually need to know: these cookies are out-of-control amazing.

I’m sorry, that wasn’t very food bloggerish of me.

I should have written you a beautiful description about how these cookies have a perfectly soft and lightly chewy texture from the ground oats and brown sugar, deep dark chocolate flavor intensified by espresso, plus warmth from the cinnamon, toasted walnuts, and good quality vanilla—all while being not overly sweet and 100% whole grain.

Like I said, out-of-control-amazing.

Though I know you have a favorite chocolate chip cookie recipe of your own, I sincerely hope that you give these chocolate chip walnut cookies (or the World’s Best Oatmeal Chocolate Chip Cookies from my cookbook) a try very soon!

Frequently Asked Questions

Can I Use Milk Chocolate Chips Instead?

While I’m partial to the flavor of dark chocolate chips, you can make these into milk chocolate chip walnut cookies instead. Just make sure to use good-quality chocolate chips.

Do I Have to Use the Espresso Powder?

The espresso powder amplifies the chocolate flavor and makes these cookies taste truly special, so I highly recommend using it. However, it is optional, so you can omit it if you prefer.

Does the Dough have to Be Refrigerated Overnight?

Letting the dough chill is important for both the taste and texture of these cookies. I’ve found that letting it chill overnight produced the best results, but even an hour of time in the refrigerator will help.

Can I Swap the Ground Oats for Additional White Whole Wheat Flour?

While oat flour is an easier swap than most for wheat flour, I have not tested the cookies this way. Oats have unique properties and do not react the same way in baking as other flours do.

  1. These cookies are Excellent!! Totally my type of cookie- they have a nice rise to them, a little crispy on the outside, but when you bite into them they have a pillowy, nutty, chocolatey gooey center. Yum!! I have made them twice in 2 days because the first night my family ate almost all of them:) And I feel a little less guilty about eating a cookie since they have oatmeal and whole-grain flour. Thanks for another great recipe!5 stars

  2. So yummy, loved the nuts and dark chocolate together!!
    Made 2 batches not going to last in my house 😋

  3. I absolutely loved these cookies and will make them often. My dough was a tad on the dry side though – what could I add to help make it a little more moist?
    They are still delicious!5 stars

    1. Hi Mary, so glad you enjoyed the recipe. Thank you for this kind review and feedback. I’ve only tested the recipe as written and have not had an issue with it being dry so I am unsure of what you could add to make it more moist. A few tips, maybe just make sure that your oats are ground up really well and that your flour is measured correctly. Hope this helps!

  4. Excellent cookie, had to put it in my recipe book. I like the fact that we use whole wheat flour and oats.5 stars
