Gooey Campfire S’mores Cookie Skillet
Description
Description
I made this the first time because I wanted all of the flavors of classic campfire s’mores without needing an actual campfire, and I honestly did not expect it to disappear as fast as it did. Once I saw the melted chocolate, toasted marshmallows, and buttery graham crumble coming together in the skillet, I already knew this one was going to be a repeat recipe. Everything people love about traditional s’mores gets baked into one warm gooey cast iron dessert with a rich brown butter chocolate chip cookie base that feels cozy from the very first bite.
As it bakes, the edges turn golden and slightly crisp while the center stays soft and molten with little pools of melted chocolate throughout. One of my favorite things about making this recipe is watching the marshmallows on top slowly toast and turn golden because it instantly gives it that nostalgic campfire look and flavor. The buttery graham cracker crumble adds just enough crunch to balance all of the gooey chocolate and soft cookie texture underneath.
I also love serving this straight from the skillet while it is still warm because everyone immediately starts reaching for a spoon before it even has time to cool down. Every bite gives you melted chocolate, toasted marshmallows, buttery graham flavor, and soft warm cookie all together with just a little flaky sea salt to keep the sweetness balanced.
This has become one of those desserts I pull out for movie nights, holidays, weekend treats, or anytime I want something fun that people get excited about the second it hits the table. It feels rich, comforting, and a little dramatic in the best way, and it is usually one of the first recipes people ask me for after trying it.

Instructions
-
Step 1 — Brown the Butter
Add the butter to a medium saucepan over medium heat. Allow the butter to melt completely, then continue cooking while stirring often until the butter becomes golden brown and smells nutty. Remove from heat and let cool for 10 minutes.
-
Step 2 — Prepare the Cookie Dough
In a large mixing bowl, whisk together the brown butter, brown sugar, and granulated sugar until smooth. Add the eggs and vanilla extract and whisk until fully combined.
Add the flour, baking soda, and salt and mix until a thick cookie dough forms. Fold in the chocolate chips and milk chocolate chunks.
-
Step 3 — Prepare the Cast Iron Skillet
Preheat oven to 350°F.
Lightly grease a 10-inch cast iron skillet with butter or nonstick spray. Press the cookie dough evenly into the skillet creating a slightly thicker edge around the outside.
-
Step 4 — Bake the Cookie Skillet
Bake for 18–22 minutes until the edges are deep golden brown and the center is still slightly soft. The cookie will continue setting as it cools.
-
Step 5 — Add the Marshmallows
Remove the skillet from the oven and arrange the marshmallow halves across the top of the warm cookie.
Return the skillet to the oven for 2–3 minutes until the marshmallows become soft and lightly toasted.
-
Step 6 — Prepare the Graham Cracker Crumble
While the marshmallows toast, combine the crushed graham crackers and melted butter in a small bowl until evenly coated.
-
Step 7 — Finish the Toppings
Remove the skillet from the oven and immediately sprinkle the buttery graham cracker crumble over the marshmallows and cookie surface.
Drizzle the melted milk chocolate across the top in thick ribbons.
-
Step 8 — Add the Finishing Salt
Lightly sprinkle flaky sea salt across the warm chocolate and toasted marshmallows for the classic sweet and salty s’mores flavor.
-
Step 9 — Rest Before Serving
Allow the skillet cookie to cool for 10 minutes so the center becomes gooey and scoopable while still staying warm and soft.
-
Step 10 — Serve Warm
Serve warm directly from the cast iron skillet with spoons for scooping into the gooey marshmallow and melted chocolate center.
