Costco Chocolate Chip Cookies Copycat Recipe
Those giant, bakery-style Costco chocolate chip cookies are hard to forget once you’ve had one. This copycat recipe gets you the same thick, chewy centers and crisp edges at home, no membership card required.
The cookies are big on purpose. A full 3 oz of dough per cookie gives you that substantial, bakery-counter result that a standard tablespoon scoop never quite delivers.
Why I Love This Recipe
The texture here is the thing: crisp on the outside, dense and chewy in the middle, with enough chocolate in every bite that you’re not hunting for chips. The browned butter is what gets you there, it adds a nutty, almost caramel-like depth that the Costco original has and most recipes miss.
These keep well, too. The high brown sugar ratio holds moisture for days, so a cookie on day three is still worth eating.
Recipe Ingredients
- 2 1/4 cups (280g) all-purpose flour – Spooned and leveled, not packed, to keep the cookies from going cakey
- 1 tsp baking soda – For lift without too much spread
- 1 tsp fine sea salt – Fine salt distributes more evenly than kosher here
- 1 cup (225g) unsalted butter – Browned and cooled; this is what gives the cookies their depth
- 1 cup (200g) dark brown sugar – Packed; the higher moisture content keeps the centers chewy
- 1/2 cup (100g) granulated sugar – Balances the brown sugar and helps the edges crisp
- 2 large eggs – Room temperature, so they incorporate without seizing the butter
- 1 egg yolk – Extra yolk adds richness and chew
- 2 tsp vanilla extract – Pure, not imitation
- 2 cups (340g) semi-sweet chocolate chips – Use a good brand; the chips make up a lot of the flavor here
- Flaky sea salt – For finishing; optional but genuinely worth it
Variations / Substitutions
- Browned butter swap – If you skip browning and use melted butter instead, the cookies will still be good but will taste noticeably flatter in flavor.
- Dark chocolate chips – Swapping semi-sweet for dark (60 to 70%) gives a slightly bitter, more intense result that works really well with the sweet dough.
- Gluten-free – A 1:1 gluten-free flour blend works here; the texture will be slightly more crumbly at the edges but still holds together.
- Dairy-free – Use a high-fat vegan butter like Miyoko’s; you can still brown it, though it foams differently, so watch the color carefully.
- Extra chocolate – Replace 1/2 cup of the chips with roughly chopped chocolate chunks for uneven pockets of melted chocolate throughout.
If you like big bakery-style bakes at home, the Levain Bakery Chocolate Chip Cookie Copycat Recipe follows a similar thick-scoop method.
How To Make Costco Chocolate Chip Cookies
Step 1: Brown the Butter
Set a light-colored saucepan over medium heat and add the 1 cup (225g) unsalted butter. Let it melt completely, then keep cooking, swirling the pan every 30 seconds or so. After about 5 to 7 minutes, the foam will subside, the milk solids will turn amber, and you’ll smell something nutty and toasty. Pull it off the heat immediately and pour it into a large mixing bowl. Let it cool for 20 minutes before you use it.
Don’t rush the cooling. If the butter is still hot when the eggs go in, you’ll scramble them, and the dough will be greasy.
Step 2: Whisk the Sugars and Eggs
Add the 1 cup (200g) dark brown sugar and 1/2 cup (100g) granulated sugar to the cooled browned butter. Whisk vigorously by hand for about 2 minutes until the mixture looks smooth and slightly lightened in color. Add the 2 large eggs, 1 egg yolk, and 2 tsp vanilla extract. Whisk for another 60 seconds until everything is glossy and ribbon-like when you lift the whisk.
This step is doing real work. The extended whisking dissolves the sugar and builds a little structure, which is what gives the final cookie that slightly crinkled top.
Step 3: Fold in the Dry Ingredients
Add the 2 1/4 cups (280g) all-purpose flour, 1 tsp baking soda, and 1 tsp fine sea salt directly to the bowl. Switch to a rubber spatula and fold until just combined, no dry streaks, about 20 to 25 folds. Don’t overmix; stopping when the flour disappears is exactly right.
The dough will be soft and a bit sticky. That’s what you want.
Step 4: Stir in the Chocolate Chips
Add the 2 cups (340g) semi-sweet chocolate chips and fold them in with the spatula until they’re evenly distributed, about 10 folds. Cover the bowl with plastic wrap and refrigerate the dough for at least 1 hour, or up to 48 hours. Longer rest means more flavor and less spread.
Step 5: Bake the Cookies
When you’re ready to bake, heat your oven to 375°F (190°C) and line 2 baking sheets with parchment paper. Scoop the dough into 3 oz (about 85g) portions, roughly the size of a golf ball, and space them 3 inches apart on the prepared sheets. Bake for 13 to 15 minutes, until the edges are set and golden brown but the centers still look slightly underdone and puffy.
They’ll firm up as they cool. Pulling them out when the centers look a little soft is the move; an overbaked cookie loses the chew you’re going for.
Step 6: Finish and Serve
Slide the parchment sheets onto a wire rack and let the cookies sit on the pan for 5 minutes to firm up enough to move. Transfer them to the rack, then immediately scatter a pinch of flaky sea salt over each one while they’re still warm. Serve warm, with the chocolate chips still melty and the tops catching the light.
Recipe Tips
- Weigh the dough portions. A kitchen scale keeps every cookie the same size, which means they all bake in the same amount of time. Eyeballing with a spoon leads to uneven results.
- Use room temperature eggs. Cold eggs can cause the browned butter to solidify into small clumps. If you forgot to take them out, set them in a bowl of warm water for 10 minutes.
- Don’t skip the chill. Rested dough spreads less and develops more flavor. One hour is the minimum; overnight is better.
- Rotate your pans halfway. At 7 minutes, swap the top and bottom sheets and rotate them front to back. Most home ovens have hot spots that will brown one side unevenly if you don’t.
Bake times at 375°F (190°C) by cookie weight:
| Dough Weight | Bake Time | Done Cue |
|---|---|---|
| 2 oz (55g) | 11 to 12 mins | Edges set, center puffed |
| 3 oz (85g) | 13 to 15 mins | Edges golden, center slightly soft |
| 4 oz (115g) | 16 to 18 mins | Edges deep gold, center matte |
How To Store
- Refrigerate – Store baked cookies in an airtight container at room temperature for up to 5 days. For longer storage, refrigerate for up to 10 days; bring them back to room temp before eating.
- Reheating – Ten seconds in the microwave brings back the soft center on a leftover cookie.
Frequently Asked Questions
Can I freeze the cookie dough?
Yes. Scoop the dough into portions, freeze them on a sheet until solid, then transfer to a zip-lock bag for up to 3 months. Bake straight from frozen at 375°F (190°C), adding 2 to 3 minutes to the bake time.
Why did my cookies spread too flat?
The most common cause is butter that was too warm when the eggs went in. If the dough felt greasy before chilling, give it a longer rest in the fridge, at least 2 hours, before baking.
Can I double the recipe?
Yes, it doubles without any changes to ratios or technique. You’ll need a very large bowl for the dough, and you’ll want to bake the sheets in batches rather than crowding the oven.
Do I have to use browned butter, or can I cream softened butter instead?
You can cream softened butter using a stand mixer, and the cookies will be good. The texture will be slightly cakier and the flavor milder since you won’t get the nutty notes that browning produces.
