Costco Chocolate Chip Cookie Recipe

Costco Chocolate Chip Cookie recipe is the antidote to flat, crispy, or underwhelming homemade cookies. This copycat masterpiece replicates the massive, bakery-style treats found in the warehouse—dense, impossibly chewy, and studded with huge pockets of melting chocolate. The secret lies in the addition of light corn syrup and molasses, which keeps the center soft and pliable while ensuring the edges remain tender. These are best enjoyed after cooling, allowing the texture to set into that signature “fudgy” crumb.

Costco Chocolate Chip Cookie Ingredients

• 1 cup (222g) Salted Butter: Softened. Using salted butter balances the extreme sweetness of the dough.
• 1 cup (246g) Brown Sugar: Packed. Provides moisture and a deep caramel flavor.
• ½ cup (115g) Granulated Sugar: Helps the edges set slightly.
• 2 Eggs: Provides structure and richness.
• ⅓ cup (108g) Light Corn Syrup: The secret ingredient for that distinctively chewy, bendable texture.
• 1 tbsp Molasses: Enhances color and adds a bakery-style depth.
• ½ tsp Vanilla Extract: Aromatic flavor.
• 3 ½ cups (532g) All-Purpose Flour: A large amount of flour creates a substantial, thick cookie.
• ½ tsp Salt: enhances flavor.
• ½ tsp Baking Soda: The leavening agent for a gentle rise.
• 1 ½ cups (300g) Chocolate Chunks: Chunks melt into pools better than standard chips.

How To Make Costco Chocolate Chip Cookies

1. Preheat the Oven: Set your oven to 350°F (180°C). Line two large baking sheets with parchment paper to prevent sticking.
2. Cream the Butter and Sugars: Use a stand mixer or hand mixer to beat the softened butter, brown sugar, and granulated sugar together until the mixture is light, fluffy, and pale in color.
3. Mix in Wet Ingredients: Scrape down the sides of the bowl. Add the eggs, light corn syrup, molasses, and vanilla extract. Beat until fully combined.
4. Add Dry Ingredients: Pour in the all-purpose flour, salt, and baking soda. Mix on low speed until a soft, sticky dough forms and no streaks of flour remain.
5. Fold in the Chocolate: Gently stir in the chocolate chunks by hand or on the lowest mixer speed to distribute them evenly throughout the dough.
6. Portion and Shape: Use a large scoop to measure out 3-tablespoon portions of dough. Roll them into smooth balls and place them on the baking sheets, leaving space for spreading. Press a few extra chunks on top for presentation.
7. Bake: Bake for 9–11 minutes. The cookies are done when the edges are just golden brown and the centers still look slightly puffed and underbaked.
8. Cool and Store: Let the cookies cool completely on the baking tray. This resting period is crucial for them to firm up and achieve the correct texture. Store in an airtight container overnight for the best “soft-batch” experience.

Recipe Tips

• Don’t Overbake: These cookies rely on residual heat to finish cooking. If they look dry in the oven, they will be hard when cooled. Pull them out while they still look soft in the center.
• Why Corn Syrup? Do not skip the corn syrup. It is an invert sugar that prevents crystallization, ensuring the cookie stays soft and chewy for days rather than turning crumbly.
• Weigh Your Flour: Because this recipe uses a high volume of flour (3.5 cups), scooping with a cup measure can lead to overpacking, resulting in a dry dough. Using a scale (532g) is the most accurate method.
• The “Bang” Method: If your cookies are puffing up too much in the oven, give the baking sheet a firm tap on the counter halfway through baking to flatten them out and create ripples.

What To Serve With Costco Chocolate Chip Cookies?

These massive cookies are rich and sweet, requiring simple pairings.

• Cold Milk: The classic choice to wash down the dense, chocolatey dough.
• Vanilla Ice Cream: Warm the cookie slightly and top with a scoop of vanilla bean ice cream for a “Pizookie” experience.
• Black Coffee: The bitterness of coffee balances the molasses and brown sugar sweetness.

How To Store Leftovers Costco Chocolate Chip Cookies?

• Room Temperature: Store in an airtight container at room temperature for up to 5 days. Add a slice of white bread to the container to keep them extra soft.
• Freeze: You can freeze the baked cookies for up to 2 months. Alternatively, freeze the raw dough balls and bake them straight from frozen, adding an extra 2 minutes to the bake time.
