Gooey Chocolate Chip Skillet Cookie, Baked in One Pan

Pull a skillet cookie from the oven and the edges sizzle golden-brown while the chocolate chips melt into pools. In about 35 minutes, one pan delivers a gooey, velvety center and crisp edges, with no scooping. Make it for a weeknight treat, a last-minute potluck, or a midnight craving like mine.

Why This Recipe Works

• Melted butter and brown sugar build chewiness: Melted butter keeps the dough soft and dense. Brown sugar's molasses holds moisture, so the cookie stays chewy for days.
• Extra yolk adds richness and a tender crumb: The extra yolk brings fat and emulsifiers that make the dough silky. That fat also softens the crumb, so each bite melts a little.
• Spoon and level flour for accurate measuring: Scooping packs flour into the cup, adding extra weight and turning the cookie dry and cakey. Spooning keeps your 190 grams honest.
• Cooling on a rack lets the center set: Residual heat keeps cooking the middle after the skillet leaves the oven. Waiting 10 to 15 minutes firms the structure without losing its soft heart.

Ingredients You'll Need

Unsalted Butter. Two sticks of melted butter form the fat base of this dough. It keeps the cookie soft and dense, so it stays chewy instead of cakey. If you only have salted butter, use it and cut the sea salt back a little.

Light Brown Sugar. Packed brown sugar brings molasses, which holds moisture and adds a caramel note. That moisture keeps the center gooey for days. Dark brown sugar works as a swap and adds even more molasses flavor.

Granulated Sugar. Plain white sugar helps the edges crisp and gives a clean sweetness. It balances the deeper molasses from the brown sugar. Superfine sugar is a good swap in the same amount.

Large Egg. A room-temperature egg blends smoothly into the warm butter and sugar. It adds structure and moisture to the dough. For an egg-free bake, use a flax egg: 1 tablespoon ground flaxseed mixed with 3 tablespoons water.

Large Egg Yolk. The extra yolk adds fat and richness, which makes the dough silky. It's the reason this cookie tastes so indulgent. If you don't have one, use a whole large egg, though the dough will be a bit less rich.

Vanilla Extract. Two teaspoons of vanilla add warmth and a floral sweetness that rounds out the buttery brown sugar. Pure vanilla paste works in the same amount if you have it on hand.

All-Purpose Flour. Spoon the flour into the cup and level it off so the dough stays light and not dry. That 190 grams gives the cookie its structure. Cake flour can stand in, though the cookie will turn out softer and more delicate.

Baking Soda. Half a teaspoon reacts with the acid in the brown sugar. That reaction helps the cookie spread and turn golden at the edges. Baking powder works as a swap, using about 1 1/2 teaspoons, but the spread will change.

Fine Sea Salt. Half a teaspoon of fine salt sharpens the sweetness and balances the chocolate. Table salt works in the same amount because it's just as fine. Kosher salt needs more, so measure by weight if you can.

Semi-Sweet Chocolate Chips. One cup of chips gives you pools of melted chocolate in every bite. Their stabilizers help them keep their shape in the oven. Chopped bittersweet chocolate is a great swap if you want a deeper, less sweet flavor.

How to Make It (Step by Step)

Mix a buttery, brown-sugar dough by hand, press it into your skillet, and bake until golden. Even if you've never baked in a skillet, you'll pull off a soft, golden center on your very first try.

1. Preheat the oven with the rack in the center, 15-20 minutes until it holds steady at 350°F / 175°C, and set your oven-safe skillet on the counter nearby.

2. Whisk the slightly cooled melted butter with the brown and granulated sugar until glossy and smooth with no lumps, 1-2 minutes at room temperature (70°F / 21°C).

3. Whisk in the egg, egg yolk, and vanilla until the batter turns thick, smooth, and pale golden, about 1 minute at room temperature (70°F / 21°C).

4. Stir in the flour, baking soda, and fine sea salt with a spatula until a soft, thick cookie dough forms with no dry streaks, 1-2 minutes at room temperature (70°F / 21°C).

5. Fold in the semi-sweet chocolate chips until they are evenly distributed through the dough, about 1 minute at room temperature (70°F / 21°C).

6. Press the dough evenly into the oven-safe skillet, pushing it to the edges and smoothing the top, about 2 minutes at room temperature (70°F / 21°C).

7. Bake until the edges turn golden-brown and the center looks set but still soft, 22-26 minutes at 350°F / 175°C.

8. Cool the skillet on a wire rack until the top feels firm to the touch and the cookie holds its shape, 10-15 minutes at room temperature (70°F / 21°C).

Recipe Notes

• Storage: Keep leftovers covered at room temperature for up to 2 days, or refrigerate for up to 5. Wrap cooled slices and freeze for up to 3 months. Warm a slice in the microwave for 15 seconds to melt the chips again.
• Key substitution: No light brown sugar? Use 3/4 cup granulated sugar plus 1 tablespoon molasses. The molasses brings back that chewy, caramel depth.
• Make-ahead tip: Mix the dough up to 2 days early and refrigerate it tightly covered. Let it soften slightly at room temperature so it presses easily into the skillet.
• Common mistake: Using a 12-inch skillet spreads the dough thin and bakes it dry. Choose a 10-inch pan for a thick, gooey center.

Tips and Tricks

• Equipment: Use a cast-iron skillet: The heavy base holds heat evenly, so the bottom and sides brown together. Thin pans heat unevenly and leave pale patches.

• Temperature precision: Hold the oven at 350°F / 175°C: Check it with an oven thermometer, since many ovens run hot or cold. Too much heat browns the edges before the center sets.

• Common mistake: Overmixing after the flour goes in: Stirring flour for too long builds gluten and makes the cookie tough. Stop as soon as no dry streaks remain.

• Flavour upgrade: Sprinkle flaky sea salt on top: Add a small pinch over the dough right before baking. The salty crunch balances the sweetness and makes the chocolate taste richer.

• Texture tip: Press the dough up the sides: Pushing dough toward the rim builds a crisp, golden edge. The center stays thick, soft, and gooey.

Frequently Asked Questions

Can I make this skillet cookie with a dairy-free or gluten-free swap?

Replace the butter with 1 cup of refined coconut oil, and use 1 cup plus 2 tablespoons of a 1:1 gluten-free baking flour in place of the all-purpose flour. Use dairy-free chocolate chips to keep the recipe dairy-free.

Can I freeze the unbaked dough and bake it straight from frozen?

Yes, press the dough into the skillet, cover it tightly with plastic wrap, and freeze for up to 2 months. Bake from frozen at 350°F for 30 to 34 minutes, until the edges are golden.

Why does my skillet cookie stick to the pan even after baking?

Run a thin offset spatula around the edges once it has cooled for 10 minutes, then loosen the bottom gently. The cookie releases most cleanly while it is still warm and firm enough to lift.

What to Serve With This

• Fresh Raspberries: Their bright, tart bite cuts straight through the brown sugar sweetness and buttery richness.
• Vanilla Bean Ice Cream: Cold and creamy, it melts into the warm, gooey center while the crisp edges stay sharp.
• Cold Milk: A classic partner that cools the palate and washes away the chocolate's sweetness between bites.
• Greek Yogurt with Honey: Thick, tangy yogurt balances the rich, sugary dough with a cool, creamy contrast.
