    • Chewy Chocolate Chunk Cookies (Better Than Costco)

    It’s a basic cookie dough recipe that uses chocolate chunks instead of chips so each bite contains even more chocolate. This is an amazingly decadent treat that you have to taste to believe. I love a good chocolate chip cookie and this Costco cookie recipe has surpassed my expectations.

    Why You’ll Love This Recipe

    • It’s better than the original: If you’ve had a Costco chocolate chip cookie, then you know how delectable they are. This recipe is even better! Especially when they’re warm from the oven.
    • It’s great anytime: You can make these for a special occasion like a party or a bake sale. They’re great just because you were craving chocolate, too. You don’t need a reason to make these!
    • It’s a quick recipe: It doesn’t take a lot of time to make these copycat Costco chocolate chip cookies. You don’t need to chill the dough so it saves you time cooking so you can spend more time enjoying.

    Costco Chocolate Chunk Cookie Ingredients

    These are the Costco cookie ingredients that I use in this chocolate chip cookie recipe. The only item that’s different from a traditional cookie is corn syrup but it’s still easily found in the baking aisle.

    Ingredients for the Chocolate Chunk Cookies on a table.
    • Butter: I use unsalted butter in this recipe. If you only have salted butter, omit the extra salt. Ensure the butter is softened enough that it mixes well with the sugar. It will be clumpy if you try to use cold butter.
    • Sugar: I find that equal parts brown sugar and caster sugar make the perfect chewy cookie. Caster sugar has smaller crystals so they mix better with the other ingredients.
    • Eggs: The eggs will provide structure to your cookies to ensure they properly hold their shape. I only use two large eggs in these cookies but it works out great every time.
    • Corn syrup: The secret ingredient in this Costco gourmet chocolate chip cookie recipe is corn syrup. It will make your cookies extra chewy and keep them that way longer!
    • Vanilla extract: A little vanilla flavor goes a long way! It enhances the flavors of the other ingredients wonderfully.
    • Flour: I use all-purpose flour for this recipe. You may try it with your favorite gluten-free blend but I haven’t so I am not sure if there will be any difference in texture or flavor.
    • Baking soda: This is an important leavening agent in these cookies. It helps them rise and spread properly.
    • Chocolate chunks: I add chunks to the cookie dough and press more on top to ensure there’s tons of chocolate in each bite.

    See the recipe card below for exact ingredient amounts, nutritional information, and detailed instructions.

    Variations

    • Pretzel toffee: Stir in crushed pretzels and toffee pieces with the chocolate chunks for a sweet and salty crunch.
    • Maple pecan: Add chopped pecans and maple syrup for a robust flavor.
    • Orange walnut: Incorporate chopped walnuts and orange zest for a fun twist.

    How to Make Costco Chocolate Chunk Cookies

    Here are the instructions to make these Costco chocolate chip cookies. Line a cookie sheet with parchment paper and preheat your oven to 350°F before you begin.

    Wet ingredients beaten in a mixing bowl.

    Step 1: Combine the wet ingredients. Beat the butter, brown sugar, and white sugar in a large bowl until they’re nice and fluffy. Then, mix in the egg, vanilla, and corn syrup until the mixture is perfectly smooth.

    Flour, salt, and baking soda mixed in a bowl.

    Step 2: Combine the dry ingredients. Combine the 3 ½ cups of flour, salt, and baking soda in a separate bowl.

    Wet and dry ingrediants mixed with a mixer forming a dough.

    Step 3: Mix into a dough. Gradually add the flour mixture to the butter and egg mixture and beat until everything is fully mixed and a soft dough forms.

    Chocolate chunks added to the cookie mixture.

    Step 4: Fold in chocolate. Add the chocolate and fold it into it to the dough.

    Six dough balls formed onto a baking sheet.

    Step 5: Form the cookies and bake. Make 2-tablespoon cookie dough balls. Place about 6 of them on the prepared cookie sheet and press a couple of chocolate chunks on top. Bake them for about 15 minutes or until the edges are golden and the centers are soft-set.

    Step 6: Cool and serve. Allow the cookies to cool for 5 minutes on the pan and then transfer them to a wire rack to cool completely. Once cooled, enjoy!

    Recipe Tips

    • Use a kitchen scale: I find that this Costco cookie recipe comes out the best when I use a kitchen scale to measure the cookie dough. It’s so accurate! Even though it seems tedious, I promise it’s worth the effort.
    • Don’t skip the extra chocolate: You’ll need all of the chocolate chunks to make these just like the Costco ones. I add them to the batter and press extra ones on top after forming the cookies. This step makes them just as indulgent!
    • Leave enough space: There needs to be plenty of space left in between each cookie so they have room to spread without becoming one giant cookie. Bake them in batches or use a second baking sheet if needed.

    Storage Directions

    • Storing: Store these cookies in an airtight container at room temperature for up to 5 days. You may freeze the cookie dough balls for up to 6 months or the baked cookies for up to 3 months.
    • Make Ahead: Feel free to prepare the cookie dough up to 24 hours ahead and store it in the refrigerator. So, you only have to bake them when you’re ready to serve!

    Serving Suggestions

    • Serve a scoop of pbj ice cream or hot chocolate ice cream on the side or in between two cookies to make a unique ice cream sandwich.
    • Have one of these gooey chocolate chip cookies with an ice-cold Nutella milkshake.

    Recipe FAQs

    Can I use granulated sugar?

    Yes, but I recommend caster sugar to achieve the best texture possible!

    Can I use margarine instead of butter?

    Nothing beats regular butter in this cookie recipe. The fat content provides better flavor and texture as well as keeps them super soft and tender.

    Why are the cookies crunchy?

    The number one reason is overbaking. Baking the cookies too long will make them dry, crumbly, and very crunchy when they cool.

    Instructions
     

    • Preheat the oven to 350°F and line a baking sheet with parchment paper. Set aside.
    • In a large bowl, use an electric mixer to cream together the butter, light brown sugar, and caster sugar until smooth and fluffy.
    • Add the eggs, corn syrup, and vanilla extract, mixing until fully incorporated.
    • In a separate bowl, whisk together 3 ½ cups of flour, salt, and baking soda until evenly combined.
    • Gradually add the flour mixture to the butter mixture, mixing until a soft dough forms.
    • Gently fold in most of the chocolate chunks, reserving some for topping.
    • Slowly incorporate the remaining ½ cup of flour, adding just enough until the dough is soft but no longer sticks to your hands.
    • Using a kitchen scale, measure out 89-gram dough balls (approximately 2 tablespoons each) and roll them between your palms.
    • Place 6 dough balls on the prepared baking sheet, spacing them apart to allow for spreading.
    • Bake for 15 minutes or until the edges are golden brown and the centers are set but still slightly soft.

    • Store your Costco chocolate chip cookies in an airtight container on the counter for up to 5 days.
    • Use a kitchen scale to ensure the cookie dough balls are equal in size so they bake properly.
