Gooey Center Chocolate Chip Cookies

These are the chocolate chip cookies that crack open to reveal a dark, fudgy center with melted chocolate pooling in every bite. The edges are crisp and deeply caramelized, while the middle stays dense and soft, almost like a brownie.

The secret is cold butter, a single egg plus an extra yolk, and a very hot oven for a short time. Each cookie is tall, craggy, and showered with flaky salt, making them taste like the best bakery version you've ever had.

This recipe delivers thick, gooey chocolate chip cookies with a satisfying contrast of textures: a crunchy golden crust and a soft, dense center that stays moist for days.

Using cold cubed butter and an extra egg yolk creates a rich, chewy crumb, while a blast of high heat sets the edges quickly, leaving the middle underbaked on purpose.

The dark chocolate chunks melt into puddles, and a sprinkle of flaky salt finishes each cookie with a savory crunch.

Ingredients

Why this recipe works

The method relies on cold butter, which is beaten just until combined rather than creamed into a fluffy state. This keeps the dough dense and prevents the cookies from spreading too much in the oven. The result is a thick, tall cookie with a fudgy interior that holds its shape.

Baking at 380°F for just 11 minutes is the key to the gooey center. The high heat caramelizes the edges quickly, while the center remains slightly underbaked, giving that soft, almost molten texture.

The extra egg yolk adds richness and moisture, and the cornstarch helps keep the centers tender.

Notes and substitutions

European-style butter has a higher fat content and lower water content, which makes the cookies more tender and flavorful. If using regular unsalted butter, it will still work, but the texture may be slightly less delicate. Keep the butter cold until the moment you mix it.

Dark chocolate chunks are preferred over chips because they melt into larger pools and offer a more intense chocolate flavor. Use a good-quality bar and chop it into rough pieces. Espresso powder is optional but enhances the chocolate depth without adding coffee flavor.

• European-style butter: Regular unsalted butter works, but reduce the salt in the dough if using salted butter.
• Vanilla bean paste: Use 2 teaspoons vanilla extract instead.
• Dark chocolate chunks: Semi-sweet or bittersweet chocolate bars, chopped, work well.
• Espresso powder: Omit it or use instant coffee granules; it deepens the chocolate flavor.
