Thick & Chunky Chocolate Chip Cookies with Walnuts

If you love walnuts and you love chocolate, you are going to LOVE these cookies! These Chocolate Chip Walnut Cookies are not your average chocolate chip cookies. They’re based on my Thick Chocolate Chip Cookie Recipe, so they stay thick and soft in the center instead of spreading while they bake.

While not quite as large as the original recipe, these chocolate chip walnut cookies are thick and chunky but they will stay soft when they’re baked and a little bit chewy thanks to the cornstarch.

Basically, if you like your chocolate chip cookies with a little texture and you enjoy walnuts, these are the cookies for you!

Key Ingredients

Here are the most important ingredients in these chocolate chip and walnut cookies. Scroll down to the recipe card for the full ingredient list and measurements.

  • Unsalted butter – At room temperature.
  • Sugar – A combination of brown sugar and granulated sugar are used in these chocolate chip cookies.
  • Cornstarch – My secret ingredient to keep these cookies extra soft!
  • Semi-sweet chocolate chips – Be sure to reserve some extra to add just before baking.
  • Chopped walnuts – See below for notes on toasting.
  • Sea salt flakes – Optional but recommended!

Toast the Walnuts

Toasting your walnuts is optional but recommended for extra flavor. It’s so easy too!

Once your oven is preheated, simply spread the walnuts on a baking sheet and bake for 6 to 8 minutes. Stir onces to ensure they’re toasted evenly. Allow to cool before adding to the dough.

How to Make Chocolate Chip Walnut Cookies

These thick chocolate chip cookies with walnuts come together in a few easy steps.

  1. Cream the butter and sugar. Beat the butter with both sugars until well creamed. Add the eggs and vanilla extract, beating until well incorporated.
  2. Add the dry ingredients. Whisk the dry ingredients in a separate bowl. Slowly add to the dough, mixing on low speed. Add the chocolate chips and walnuts.
  3. Bake. Scoop the dough onto the baking sheet, two inches apart. Bake for 11 to 13 minutes.

Tips for Success

Here are a few things to keep in mind while making these cookies.

  • Make your dough balls a little larger. I use a large cookie scoop to portion out the dough but instead of leveling off the cookie scoop, I make them just a little larger so the cookies and nice and thick.
  • Make sure the butter is not too soft. The butter should be at room temperature but not melted or too soft. Think soft enough for your finger to make a dent if you push on it but not so soft the stick loses shape. Butter that is too soft will cause the cookies to spread and flatten.
  • How to tell when the cookies are done? The edges should be crisp while the centers should be slightly underbaked and not too gooey.
  • Cool on the baking sheet. Do not transfer these cookies immediately to the cooling rack. Allow them to cool for 15 minutes or so on the baking sheet, so the centers can set and firm up a bit.

Storage & Freezing

These walnut chocolate chip cookies will last for 3 or 4 days when stored in an airtight container at room temperature. Keep in mind that they will be softer and chewier the sooner you eat them.

They also freeze well. I like to wrap each one individually then place it in an airtight container to prevent freezer burn. Thaw on the counter or if you’re impatient like me, pop one in the microwave for 30 seconds. Warm cookie heaven!

  3. In a separate bowl, combine the remaining dry ingredients. Stir to combine and slowly add the dry ingredients into the dough, mixing on low speed until the dough starts to form. Before the dough thickens, add the chocolate chips and walnuts. Save ¼ cup of chocolate chips for topping the cookies. Beat until incorporated. Set aside.
  4. Using a large cookie scoop to scoop the dough and place the dough 2 inches apart on the baking sheet. Place extra chocolate chips on top of the dough. Bake for 11-13 minutes.
