How to Make Costco‑Style Chocolate Chip Cookies at Home

Few bakery items are as iconic as Costco’s oversized chocolate chip cookies. Soft in the center, slightly crisp on the edges, and packed with melty chocolate, they’ve become a favorite treat for shoppers who can’t resist grabbing a box on the way out.

The good news? You don’t need a membership card to enjoy them at home. This copycat recipe captures the same chewy texture and rich flavor, giving you bakery‑style cookies fresh from your own oven.

What are Costco Chocolate Chip Cookies?

Costco chocolate chip cookies are the oversized, bakery‑fresh treats sold in the United States through Costco’s in‑store bakeries. Known for their jumbo size, chewy centers, and crisp edges, they quickly became a customer favorite after Costco expanded its bakery program in the late 1990s and early 2000s.

The tradition of the chocolate chip cookie itself dates back to 1938 in Massachusetts, when Ruth Graves Wakefield created the first version at the Toll House Inn.

You don’t need a commercial bakery setup to get that signature Costco cookie texture—just a few reliable kitchen tools will make the process smooth and simple.

• Mixing bowls (large and medium)
• Stand mixer or hand mixer
• Measuring cups and spoons
• Rubber spatula or wooden spoon
• Baking sheets

How to Make Costco‑Style Chocolate Chip Cookies at Home

These jumbo cookies are soft in the center, slightly crisp on the edges, and packed with chocolate chunks. Follow these simple steps to recreate the Costco bakery favorite in your own kitchen.

1. Preheat the oven: Set your oven to 350°F (175°C). Line a baking sheet with parchment paper or a silicone mat.
2. Cream the butter and sugars: In a stand mixer or with a hand mixer, beat the softened butter, brown sugar, and granulated sugar until pale and fluffy.
3. Add wet ingredients: Scrape down the bowl, then mix in the egg, corn syrup, molasses, and vanilla until smooth and well blended.
4. Incorporate dry ingredients: Add the flour, salt, and baking soda. Mix on low speed until a sticky dough forms—don’t overmix.
5. Fold in chocolate chunks: Stir in the chocolate chunks with a spatula, making sure they’re evenly distributed throughout the dough.
6. Shape the cookies: Scoop about 3 tablespoons of dough per cookie, roll into balls, and place on the prepared baking sheet. Press a few extra chocolate chunks on top if desired.
7. Bake and cool: Bake for 9–11 minutes, until the edges are golden and the centers look slightly underdone. Let cookies cool on the pan before transferring to a wire rack.

These cookies are best enjoyed fresh, but for the signature soft Costco‑style edges, store them overnight in an airtight container—the texture becomes even more irresistible by the next day.

Personalization & Tips – Costco Chocolate Chip Cookies

These cookies are already big, chewy, and chocolate‑packed, but a few small tweaks can make them perfectly suited to your taste or occasion.

• Chocolate swap – Use a mix of milk, dark, or white chocolate chunks for a bakery‑style variety.
• Nutty crunch – Stir in chopped walnuts or pecans for extra texture.
• Extra chewy – Chill the dough for 30 minutes before baking to get thicker, chewier cookies.
• Smaller batch – Scoop 2 Tbsp portions instead of 3 Tbsp for more, smaller cookies.
• Bakery look – Press a few chocolate chunks on top of each dough ball before baking for that picture‑perfect finish.
• Storage tip – Keep cookies in an airtight container overnight to soften the edges, just like Costco’s signature style.

With these easy adjustments, you can make your Costco‑style cookies uniquely yours—whether you want them extra gooey, nutty, or perfectly Instagram‑ready.
