Ingredients for Costco Chocolate Chunk Cookies

*Ingredient amounts are located in the recipe card at the end of this post.

• All-Purpose Flour: gives these cookies their structure, so measuring it right keeps them from turning dense. Sift it for that perfect, light texture.
• Baking Powder & Baking Soda: The dynamic duo that ensure the cookies have that sought-after rise and airy texture. Together, they strike a unique balance in leavening, which is key to achieving the signature look and feel of these famous cookies. It’s all about getting those quantities just right for the perfect cookie lift.
• Salt: The use of salt in baked goods, like these chocolate chip cookies, helps balance and enhance their sweetness.
• Softened Butter: The base for chocolate chip cookies provides that creamy, dreamy cookie dough texture we all love. To soften it quickly without melting, just cut your butter into small pieces and let it sit out for about 30-45 minutes; it should be perfect for mixing into your dough by then. Also, choosing between salted and unsalted butter can really tweak the flavor profile of your cookies. I tend to go for unsalted to control the sodium in my recipe, but if you’re looking for a slight kick, salted butter might be your secret ingredient.
• Large Eggs: Enrich the cookie dough with moisture and structure, blending seamlessly when at room temperature, ensuring no shell bits sneak in.
• Vanilla Extract: Complements chocolate chunk nuances with a pure, rich essence.
• Semi-Sweet Chocolate Chunks: Elevate these cookies’ flavor and texture—chop bars for rustic chunks or use pre-cut for ease, perfectly balancing sweetness.

Costco Chocolate Chunk Cookies Recipe

[Step 1] In a medium mixing bowl, whisk or sift together the flour, baking powder, baking soda, and salt. Set aside.

[Step 2] In a stand mixer or mixing bowl, beat the softened butter with the white and brown sugars until light and fluffy. Mix in the eggs one at a time. Add the vanilla and mix until combined.

[Step 3] Add the flour mixture to the butter mixture and mix until all of the flour has been incorporated, scraping the sides of the bowl as necessary.

[Step 4] Gently stir in the chocolate chunks, or use a dough hook, if using a stand mixer. Refrigerate the dough for 45-60 minutes to ensure the cookies do not flatten when baking.

[Step 5] Use a 1/4 cup cookie scoop to measure the cookie dough and place on a parchment paper-lined baking sheet. Bake at 375 for 15-20 minutes.

[Step 6] When the edges begin to brown, remove from the oven and allow the cookies to rest for 5 minutes before transferring the cookies to a wire rack to cool.
