Giant Gooey Cast Iron Skillet Cookie
This giant cast iron skillet cookie is the dessert you make when you want a fresh, warm chocolate chip cookie without scooping a dozen onto a sheet pan. One bowl, one skillet, and no mixer means you get a thick, buttery cookie with crisp edges and a soft, almost fudgy center in under forty minutes.
Top it with a scoop of vanilla ice cream while it’s still warm and you have a dessert that feels like a special occasion even on a Tuesday night.
Why This Skillet Cookie Works
The cast iron holds heat so well that the edges set up almost like a blondie, while the center stays soft and gooey. You get all the contrast in one slice, no rotating pans or waiting for multiple batches.
I keep coming back to this version because it uses melted butter, which means no waiting for butter to soften and a chewier, denser texture that holds up to a scoop of ice cream. It also dirties exactly one bowl and one skillet, so cleanup takes about thirty seconds.
The whole thing bakes as one giant cookie, which feels way more fun than a tray of individual ones. You bring the skillet straight to the table, people dig in, and somehow it tastes better than anything that got portioned out in the kitchen.
Ingredients
- 1/2 cup (1 stick) unsalted butter, melted and slightly cooled: melted butter makes the cookie extra chewy
- 1/2 cup packed light brown sugar: gives a molasses depth and keeps the center soft
- 1/4 cup granulated sugar: helps the edges crisp up
- 1 large egg, at room temperature: cold egg can make the batter seize, so let it sit out while you gather everything else
- 1 1/2 teaspoons vanilla extract: use the real stuff if you have it, the flavor really comes through
- 1 cup plus 2 tablespoons all-purpose flour, spooned and leveled: too much flour makes the cookie dry, so don’t scoop straight from the bag
- 1/2 teaspoon baking soda: the only leavener, just enough lift for a tender crumb
- 1/2 teaspoon kosher salt: balances the sweetness and rounds out the chocolate
- 3/4 cup semisweet chocolate chips or chunks: chunks melt into little pockets; chips hold their shape better
Variations / Substitutions
- Brown the butter: cook the butter until it smells nutty and the milk solids turn amber, then let it cool slightly before mixing. It adds a deeper toffee note.
- Swap the chocolate: chopped dark chocolate or a mix of milk and white chocolate both work. Use the same total weight.
- Add a handful of chopped nuts: toasted pecans or walnuts folded in with the chocolate give a nice crunch.
- Make it gluten-free: replace the flour with a 1-to-1 gluten-free baking flour blend that contains xanthan gum. The texture will be slightly more crumbly but still delicious.

How to Make Cast Iron Skillet Cookie
Step 1: Whisk the Butter and Sugars
Preheat your oven to 350°F (175°C). In a large bowl, whisk together the 1/2 cup melted butter, 1/2 cup brown sugar, and 1/4 cup granulated sugar for about 1 minute, until the mixture looks smooth and glossy with no separated butter pooling around the edges.
You are looking for a thick, slightly grainy paste that flows slowly when you tilt the bowl. If the butter was still too hot, the sugar might look greasy at first, but it will come together as you whisk.
Step 2: Stir in the Egg, Vanilla, and Dry Ingredients
Crack the egg into the bowl, add the 1 1/2 teaspoons vanilla, and whisk until fully combined and the batter lightens just a shade. Switch to a spatula or wooden spoon and fold in the 1 cup plus 2 tablespoons flour, 1/2 teaspoon baking soda, and 1/2 teaspoon salt. Stir only until there are no dry streaks left, then fold in the 3/4 cup chocolate chips.
The dough will feel soft and a little sticky, almost like a thick brownie batter. Stop stirring as soon as the flour disappears. Overworking the dough will give you a tougher, less tender cookie.
Step 3: Press and Bake the Cookie
Lightly grease a 10-inch well-seasoned cast iron skillet (a little butter on a paper towel is all you need). Scrape the dough into the skillet and use the back of your spatula or damp fingers to press it into an even layer that reaches all the way to the edges. Bake for 22 to 25 minutes, until the top is deep golden and no longer shiny and the edges are pulling away from the sides.
A toothpick pushed into the very center will come out with a few moist crumbs attached, not wet batter. The cookie will look slightly puffed when it comes out but will settle and crack as it cools, which is exactly what you want.
Step 4: Cool, Slice, and Serve
Let the skillet rest on a wire rack for 10 minutes so the center can finish setting up. Run a knife around the edge if needed, then slice into wedges directly in the pan and serve while still warm.
A scoop of vanilla ice cream melting into the cracks, or a drizzle of warm salted caramel, turns this into the kind of dessert people hover around until the last crumb is gone.
Tips for the Best Skillet Cookie
- Use a well-seasoned skillet.: A newer, unseasoned pan can stick even with greasing. If your skillet isn’t super slick, rub it with a thin layer of neutral oil and heat it for a few minutes before greasing for the dough.
- Don’t overbake it.: The cookie continues cooking from the skillet’s heat after it comes out of the oven. Pull it when the center looks just barely set, with a slight jiggle, and it will finish to a soft, gooey texture.
- Let it rest before cutting.: Ten minutes off the heat gives the structure time to firm up enough to slice cleanly without falling apart. You can spoon it straight from the pan sooner if you prefer a molten center; just know it will be messier.
- Customize the mix-ins.: Swap half the chocolate chips for chopped pretzels for a salty-sweet crunch, or use white chocolate and dried cranberries for a holiday version.
Bake times by skillet size (for a well-seasoned pan at 350°F):
| Skillet Size | Bake Time (approx.) |
|---|---|
| 8-inch | 25 to 28 minutes |
| 10-inch | 22 to 25 minutes |
| 12-inch | 18 to 22 minutes |
Storing Leftovers
- Refrigerate: Cover the skillet tightly with foil or transfer slices to an airtight container. The cookie keeps for up to 4 days in the fridge.
- Reheating: Warm individual slices in a 300°F oven for 5 to 7 minutes, or microwave for 20 seconds. The edges will recrisp in the oven.
What to Serve With Cast Iron Skillet Cookie
Vanilla ice cream is the classic move because the cold, creamy sweetness plays off the warm, salty chocolate. Salted caramel sauce works beautifully too, the salt cutting through the richness. For a little crunch, a scattering of flaky sea salt right before serving makes the chocolate pop.
Frequently Asked Questions
Can I make this in a regular cake pan instead of cast iron?
You can, but the edges will be softer and you won’t get the same crisp, caramelized crust. A 9-inch metal cake pan works best if you don’t have cast iron; reduce the bake time by about 3 minutes.
My cookie is still raw in the middle. What went wrong?
Your oven might run cool, or the skillet may not have been fully preheated when the dough went in. Next time, let the empty skillet sit in the heating oven for 5 minutes before greasing and filling it.
Can I double the recipe for a larger group?
Yes. Double all ingredients and use a 12-inch skillet. The bake time will be closer to 25 to 28 minutes. Watch for the same visual cues: golden top, edges pulling away, and a toothpick with moist crumbs.
What if I only have salted butter?
Just reduce the added salt to a generous pinch, about 1/4 teaspoon. The cookie will still be balanced.
