These Copycat Levain Bakery Chocolate Chip Cookies are extra large, extra thick cookies with a soft, gooey inside and loaded with chocolate chips and walnuts. The supersized cookie takes a chocolate chip cookie to a whole new level of indulgence! They are based on Levain Bakery’s signature chocolate chip walnut cookie that has been around for over 25 years! I adapted this recipe from Modern Honey with a comparison to the Levain bakery’s cookie and couldn’t be happier with the results!

Copycat Levain Cookies Ingredients & Smart Substitutions

  • Butter: Using cold, unsalted butter helps the cookies get nice and chunky without flattening out too much. If you are looking to get the same texture, richness, and flavor as the famous bakery’s cookies, make sure the butter is cold. If using salted butter, you may want to lessen the amount of salt in the recipe.
  • Sugar: Both light brown sugar and granulated sugar have a purpose in these cookies. The brown sugar adds moisture, a caramel-like flavor, and a chewy texture. The granulated sugar adds sweetness and gives the outside a lovely crispiness.
  • Flour: Get out some cake flour and all-purpose flour for the cookies. Cake flour is lower in protein than all-purpose flour, so it helps give the cookies a little bit of a cake-like texture. The all-purpose flour gives the cookies a little structure. They work perfectly together in these cookies! However, if you don’t have cake flour, you can make your own. Or, use 3 cups of all-purpose flour. The cookies may have a denser texture, but will still be good!
  • Cornstarch: Cornstarch helps the large cookies stay together, but still have a soft, chewy texture.
  • Chocolate Chips: It’s hard to have chocolate chip cookies without chocolate chips! I added semi-sweet chocolate chips. But, you could try other candy chips like milk chocolate, dark chocolate, white chocolate chips, butterscotch, or your favorite. A combination of a couple would be delicious, too!
  • Nuts: Since this cookie is based off of a chocolate chip walnut cookie, I stuck with chopped walnuts. However, other nuts would be good, too, like almonds, pecans, or your favorite. If you don’t want to add nuts, just leave them out and enjoy your massive chocolate chip cookies!

The Secret To Thick & Chewy Cookies: Chilling The Dough!

I encourage you to NOT skip the step of chilling the cookie dough. Chilling the dough helps make cookies thicker and chewier. In addition, it stops the cookies from spreading too much in the oven, so they stay nice and puffy. Plus, chilling the dough makes the flavors taste better and the dough easier to handle. Overall, it helps you bake the best cookies!

How To Tell When Copycat Levain Chocolate Chip Cookies Are Perfectly Baked

Since these cookies are so thick (not complaining, though), it’s hard to check them for doneness just by the looks of them. Your best bet is to use an internal thermometer. When inserted into the cookies, the temperature should read anywhere from 175ยฐF (for a fudgier cookie) to 200ยฐF. The edges should be set.

How To Store Copycat Chocolate Chip Cookies

Once cooled and set, store the cookies in an airtight container at room temperature. They will last up to 2-3 days. If you keep the cookies in the refrigerator, they can last up to a week.

Freezing Chocolate Chip Walnut Cookies

You can freeze these chocolate chip walnut cookies before they are baked or after. Here is how:

  • To freeze after being baked, let the cookies cool completely. Then, store them in a freezer-safe container, making sure to label and date the container. Let them thaw at room temperature when ready to enjoy.
  • To freeze the cookie dough, scoop the dough onto a lined baking sheet. Place the baking sheet in the freezer for about an hour, or until frozen. Once frozen, store the cookie dough in a freezer-safe container for up to three months, labeling and dating the container. When ready to bake, simply bake from frozen, adding a couple of minutes to the baking time.
