Why mess with perfection? These Chocolate Chip Cookies stick to the classic formula you know and love: buttery, chewy, and irresistibly chocolatey.

Before I became a food blogger, I spent several years in gourmet food sales, supplying world-class chefs with the finest ingredients money could buy. Once a year, we packed up and headed to the Summer Fancy Food Show at the massive Javits Center in NYC—a wonderland of culinary imagination. The pastry competitions were my favorite: towering chocolate sculptures that seemed to defy physics, and cakes so elaborate they belonged in a museum. Think multi-layered masterpieces filled with mousse, sponge, silky ganache, even shimmering orbs of suspended jelly, all crowned with perfectly tempered chocolate decorations, edible gold leaf, and shiny glazes.
After the judging wrapped, my coworkers and I were lucky enough to snag the leftovers of these edible works of art. And yes, they were as delicious as they were beautiful. But here’s my little secret: I’d take a warm, freshly baked chocolate chip cookie over any one of those extravagant creations.
Maybe it’s nostalgia, or maybe it’s the magic of butter, sugar, and chocolate doing exactly what they’re meant to do, but for me, nothing beats the comforting simplicity of a perfect chocolate chip cookie. That’s why I love this recipe so much. It’s everything a chocolate chip cookie should be—soft and chewy in the center, lightly crisp on the edges, packed with melty chocolate, and flavored with that caramelly brown sugar depth we all crave. The cornstarch keeps the crumb tender, the extra egg yolk adds richness, and a long chill ensures thick, bakery-style cookies that don’t spread. No fancy techniques, no special equipment, just classic, crowd-pleasing cookies. Care to take a bite?

Tips for moist & chewy chocolate chip cookies
If you want soft, chewy, picture-perfect cookies, a few key techniques make all the difference. Brown sugar is essential—its molasses content adds moisture, chew, and deeper flavor, so don’t swap it for all white sugar. Use softened (not melted) butter, and if you’ve softened it in the microwave, let it cool before mixing to avoid greasy, flat cookies. Room-temperature eggs help the dough blend smoothly and prevent the butter from re-solidifying, which can lead to dense, uneven cookies. For the right texture, mix the dough only until it comes together; overmixing develops gluten, which can cause spreading and a tougher bite. Be sure your oven is preheated to help the edges set while the centers stay soft. And perhaps the biggest secret of all: chill the dough for at least a few hours. This allows the flour to hydrate, the butter to firm up, and the flavors to deepen, giving you thicker, chewier cookies that bake evenly. Lastly, scoop taller dough mounds instead of wide ones. They spread less and stay softer in the center. Follow these steps and you’ll have bakery-style cookies every time.

How do I store leftovers?
Once the cookies are completely cooled, store them in an airtight container at room temperature for up to 1 week. To keep them soft, you can add a slice of bread or a few marshmallows to the container; they’ll help maintain moisture without affecting the flavor. To freeze, place them in a single layer on a baking sheet to freeze solid, then transfer to a freezer-safe bag and store for up to 3 months. When you’re ready to enjoy, let them thaw at room temperature or pop them in a low oven for a few minutes to bring back that just-baked warmth.

Serving suggestions
If you’re going to have chocolate chip cookies, you need a big glass of milk. And by big, I mean wide enough to fit a cookie. After all, you have to dunk it, right? Sandwich a scoop of vanilla or coffee ice cream between two cookies for an easy ice cream sandwich. Crumble them over pudding, Frozen Yogurt, or a bowl of Homemade Soft Serve Ice Cream. However you serve them, these cookies have a way of making any moment feel a little more special.

Chocolate Chip Cookies
Ingredients
- 2 1/4 cups all-purpose flour
- 1 teaspoon baking soda
- 1 1/2 teaspoons cornstarch
- 1/2 teaspoon salt
- 3/4 cup unsalted butter softened
- 3/4 cup packed light or dark brown sugar
- 1/2 cup granulated sugar
- 1 large egg plus 1 egg yolk at room temperature
- 2 teaspoons pure vanilla extract
- 1 1/4 cups semisweet chocolate chips or chocolate chunks plus more for topping, optional
Instructions
- In a large bowl, whisk together the flour, baking soda, cornstarch, and salt.
- In a separate medium bowl, beat together the softened butter, brown sugar, and granulated sugar until smooth, ensuring no sugar lumps remain. Add the egg, egg yolk, and vanilla extract, mixing until well combined. The mixture will be somewhat thin.

- Pour the wet ingredients into the dry ingredients. Stir together with a large spoon or rubber spatula until the dough forms. It will be soft and may seem greasy. Fold in the chocolate chips, doing your best to distribute them evenly.

- Cover the dough tightly with plastic wrap and refrigerate for at least 3 hours, or up to 3 days. For best results and less cookie spreading, chill overnight.
- When ready to bake, let the dough sit at room temperature for 10 minutes to soften slightly. Preheat the oven to 325°F and line baking sheets with parchment paper or silicone baking mats.
- Use a cookie scoop or tablespoon to measure out the dough. For extra-large cookies, use 3 scant tablespoons of dough; for medium-large cookies, use 2 heaping tablespoons. Roll the dough into tall, cylindrical balls and place them on the prepared baking sheets, spacing them out to allow for spreading.

- Bake for 12–13 minutes, or until the edges are just lightly browned. The centers will appear soft but will firm up as they cool. For extra-large cookies, you may need up to 14 minutes of baking time.

- Optionally, press a few extra chocolate chips on top of the warm cookies for a bakery-style look. Cool the cookies on the baking sheets for 10 minutes, then transfer them to a wire rack to cool completely.
