S’mores Chocolate Chip Cookie Skillet
If you love a chewy, gooey cookie with crisp edges, this S’mores Chocolate Chip Cookie Skillet is going to be your new obsession. It’s a warm, melty skillet chocolate chip cookie baked in a cast iron pan, loaded with graham cracker crunch and big chunks of Hershey’s milk chocolate, then finished with toasty marshmallows right on top.
If you want a few more sweet options on the table, I’d add a slice of this boozy chocolate tart, a batch of these bakery-style German chocolate cookies, or keep it extra gooey with this warm lava cake. And if your crowd loves cookie cakes, this caramel-coconut cookie cake is always a fun one.
Why You’ll Love It (And When to Make It)
- Big s’mores flavor without the campfire
- Crispy edges + gooey center (cast iron magic)
- Easy, fun “grab a spoon” dessert for sharing
- Perfect for cozy weekends, movie nights, sleepovers, and game day
- Even better, topped with ice cream or served with coffee/hot chocolate
Ingredients
- Unsalted butter (browned) – Browning adds a rich, nutty flavor that makes the cookie taste extra bakery-style.
- Brown sugar – Keeps the center chewy and adds a deeper caramel-like sweetness.
- White granulated sugar – Helps the edges crisp up and balances the chew.
- Eggs – Bind everything together and give the cookie structure.
- Heavy cream – Adds richness and helps keep the texture soft and gooey.
- Vanilla extract – Warms up the flavor and makes the chocolate pop.
- All-purpose flour – The base that gives the skillet cookie its body.
- Baking soda – Helps the cookie spread and gives those crisp, golden edges.
- Baking powder – Adds a touch of lift so the center isn’t too dense.
- Salt – Brings out the chocolate and balances the sweetness.
- Semisweet chocolate chips – Classic chocolatey bites throughout the dough.
- Hershey’s milk chocolate bars – Melt into big, gooey pockets for true s’mores vibes.
- Graham crackers (crushed) – Adds that signature s’mores crunch and toasty flavor.
- Marshmallows (halved) – Toast on top and give you that sticky, campfire-style finish.

How to Make This S’mores Chocolate Chip Cookie Skillet
Step 1: Preheat + prep the skillet
Preheat your oven to 350°F (175°C). Lightly butter or spray a 10-inch cast iron pan.
Step 2: Brown the butter
Melt the butter in a saucepan over medium heat. Keep stirring as it foams, then turns golden and smells nutty (about 5–7 minutes). Pour into a large mixing bowl and let cool slightly (you want warm, not blazing hot).
Step 3: Mix the wet ingredients
Whisk the brown sugar and white sugar into the browned butter until glossy. Add eggs one at a time, whisking after each. Stir in heavy cream and vanilla until smooth.
Step 4: Add the dry ingredients
In a separate bowl, whisk together flour, baking soda, baking powder, and salt. Fold the dry mix into the wet ingredients just until combined (don’t overmix).
Step 5: Fold in chocolate + graham crackers
Fold in semisweet chocolate chips and crushed graham crackers (reserve 1–2 crackers’ worth for topping). Break the Hershey’s bars into chunks and fold them in too.
Step 6: Press dough into the pan
Press the dough evenly into your prepared skillet so it bakes as one giant cookie.
Step 7: Add marshmallows + crunchy topping
Arrange halved marshmallows on top, pressing them in slightly. Sprinkle Hershey’s milk chocolate bars and reserved graham cracker crumbs over the top for extra crunch.
Step 8: Bake
Bake for 28–32 minutes, until edges are golden and the center is just set (it will continue setting as it cools).
Step 9: Cool briefly + serve
Let cool about 10 minutes. Serve warm, preferably with ice cream, so the center stays gooey.
Hint: If your marshmallows start browning too fast but the cookie isn’t done yet, loosely tent the skillet with foil for the last few minutes.
Substitutions
- Butter: If you don’t want to brown it, you can use melted butter, but you’ll lose that toasted, nutty flavor that makes this cookie skillet taste extra special.
- Chocolate: Swap Hershey bars for another milk chocolate bar, or use all semisweet if you prefer less sweetness.
- Graham crackers: Digestive biscuits work in a pinch (texture will be a bit different).
- Cast iron skillet: You can bake this in a 10-inch oven-safe metal skillet or a 9×9 baking pan (bake time may change slightly).
Variations
- Peanut butter twist: Add peanut butter chips or swirl a few spoonfuls of peanut butter into the dough before baking.
- Deluxe: Finish with a pinch of flaky salt and extra chocolate chunks right after baking.
- Kid-friendly “build-your-own”: Bake without marshmallows, then let everyone top their slice with marshmallows + chocolate + crushed grahams and microwave for 10–15 seconds.
Equipment
Equipment can have a big impact on how this turns out.
- 10-inch cast iron skillet (best for crisp edges and a gooey center)
- Mixing bowls
- Whisk + spatula
- Medium saucepan (for browning butter)
- Measuring cups/spoons
If you use glass or ceramic, the center may take longer to set and edges may be softer (and bake time can increase).
Storage
- Room temp: Cover the skillet tightly and keep at room temperature for 1–2 days.
- Fridge: For longer storage, refrigerate for up to 3–4 days. Rewarm in the microwave in short bursts so it’s gooey again.
- Freezing: You can freeze slices, but marshmallows can get a little weird after thawing. If freezing, wrap slices well and freeze up to 1 month.
