S’more Cookie Skillet: Gooey, Chocolatey, and Ready in 30 Minutes
I’ll be honest—the first time I made a s’more cookie skillet, I wasn’t sure it would work. How could you possibly get marshmallows to stay fluffy and gooey on top of a warm cookie without turning into a burnt, deflated mess? But here’s what I learned: timing is everything, and this s’more cookie skillet is actually one of the most forgiving desserts you can make. The magic happens in those last few minutes of baking when the marshmallows just start to puff and turn golden, and the chocolate cookie underneath stays warm and chewy. It’s like bringing campfire vibes straight into your kitchen without needing to leave your house or deal with smoke in your hair.
This recipe came about on a random Tuesday when my kids were begging for s’mores but it was pouring rain outside. I didn’t want to disappoint them, so I grabbed a box of brownie mix (yes, brownie mix—I’ll explain why in a second), some chocolate chips, marshmallows, and graham crackers, and threw together this skillet dessert. What emerged from the oven was pure magic: a warm, gooey chocolate base with perfectly toasted marshmallows on top and crunchy graham cracker crumbles scattered everywhere. My family devoured it in minutes, and I’ve been making it ever since for everything from weeknight desserts to potlucks and casual entertaining.
The beauty of this s’more cookie skillet is that it’s incredibly flexible. You can use a box mix to keep things simple, or you can use homemade cookie dough if you want to get fancy. You can bake it in a cast iron skillet for those gorgeous crispy edges, or use any oven-safe dish you have on hand. The whole thing comes together in about 30 minutes, which means you can satisfy a serious dessert craving without spending your entire evening in the kitchen. It’s the kind of recipe that feels special enough to serve to guests but easy enough to make on a random Tuesday night.
Why You’ll Love This Recipe
There are so many reasons to make this s’more cookie skillet, and I’m going to walk you through my favorites. First, it’s genuinely easy. Even if you’ve never made a skillet dessert before, you can absolutely nail this. There’s no fancy technique, no temperamental ingredients, and no reason to stress. You mix, you press, you bake, and you’re done.
Second, it’s a total crowd-pleaser. I’ve served this at book club, family gatherings, and casual dinners with friends, and every single time, people ask for the recipe. There’s something about the combination of chocolate, marshmallows, and graham crackers that just makes people happy. It taps into that nostalgic s’mores feeling that everyone loves, but it’s warm and gooey and served in a way that feels a little more sophisticated than eating it off a stick.
Third, it’s visually stunning. When you pull this out of the oven with those golden, puffy marshmallows on top, it looks like you spent hours on it. Your guests won’t believe how simple it actually is. The contrast of the dark chocolate cookie, the white marshmallows, and the tan graham crackers is just beautiful.
Finally, it’s customizable. Want to add peanut butter? Go for it. Prefer dark chocolate? Use dark chocolate chips. Want to make it gluten-free? Use a gluten-free brownie mix. This recipe is your canvas, and you can paint it however you like.
Ingredients
- 1 box brownie mix (plus ingredients listed on the box: usually oil, water, and eggs)
- 1 cup chocolate chips
- 2 cups mini marshmallows (or 1 cup large marshmallows, halved)
- 1 cup graham cracker crumbles
- 2 tablespoons butter, melted
- 1 tablespoon brown sugar
- Pinch of sea salt
Sophia’s Tip: I use mini marshmallows because they distribute more evenly across the skillet and toast more uniformly than large ones. If you only have large marshmallows, just cut them in half with kitchen scissors (spray them with cooking spray first so they don’t stick). The brownie mix is my secret weapon here—it gives you a fudgy, chocolatey base without any fuss, but if you prefer, you can absolutely use a chocolate chip cookie dough recipe instead. Just use about 1.5 to 2 cups of dough.
Optional Add-Ins and Variations
This is where you get to have fun. Here are some of my favorite ways to customize this recipe:
- Peanut Butter Version: Swirl 3 tablespoons of peanut butter into the brownie batter before pressing it into the skillet. It’s like a peanut butter cup meets a s’more.
- Salted Caramel: Drizzle 2 tablespoons of salted caramel sauce over the chocolate layer before adding marshmallows. The sweet and salty combination is incredible.
- Cookies and Cream: Crush up 4 or 5 Oreos and mix them into the brownie batter. Add the marshmallows and graham crackers as usual.
- Nutella Lover: Spread a thin layer of Nutella over the baked brownie layer before adding marshmallows. It adds a hazelnut richness that’s absolutely delicious.
- Dark Chocolate Version: Use dark chocolate chips instead of semi-sweet, and add 1 tablespoon of cocoa powder to the brownie mix for extra depth.
Step-by-Step Instructions
- Preheat and prepare: Heat your oven to 350°F. If you’re using a cast iron skillet, place it in the oven while it preheats. If you’re using a regular baking dish, just grease it lightly with cooking spray or butter.
- Make the brownie batter: Follow the box mix instructions, combining the mix with oil, water, and eggs (or whatever your box calls for). Stir until just combined—don’t overmix. The batter should be thick and fudgy.
- Add chocolate chips: Fold in the chocolate chips. This step is optional, but I love the extra chocolate flavor and texture. It makes the cookie layer more interesting.
- Press into the skillet: Carefully remove the hot skillet from the oven (use an oven mitt—it’s hot!) and pour the batter into it. Use a spatula or the back of a spoon to press it into an even layer. It doesn’t have to be perfect; rustic is actually better here.
- Bake the base: Bake for 15 to 18 minutes. You want the edges to be set and the top to look slightly underbaked. The center should still jiggle just a tiny bit when you gently shake the skillet.
- Add marshmallows and graham crackers: Remove the skillet from the oven. Scatter the marshmallows evenly over the top. In a small bowl, toss the graham cracker crumbles with melted butter, brown sugar, and a pinch of sea salt. Sprinkle this mixture over and around the marshmallows.
- Finish baking: Return the skillet to the oven for 5 to 7 minutes, until the marshmallows are puffed and just starting to turn golden on the edges. Watch it carefully during this step—marshmallows can go from golden to burnt in about 30 seconds.
- Cool slightly: Remove from the oven and let it cool for 3 to 5 minutes. This gives the marshmallows time to set slightly while staying gooey inside.
Sophia’s Kitchen Note: The key to perfect marshmallows is not overbaking them. They should look slightly underdone when you pull them out—they’ll continue to cook as the skillet cools. If you bake them until they’re deeply golden, they’ll deflate and become tough. Also, if you’re using a regular baking dish instead of cast iron, the baking times might be slightly different. Check for doneness by gently shaking the skillet—the edges should be set but the center should still have a tiny bit of jiggle.
Common Mistakes to Avoid
Overbaking the marshmallows: This is the number one mistake I see. People wait for the marshmallows to be deeply golden, but by then they’ve already started to deflate. Pull the skillet out when the marshmallows are just barely golden on the edges. They’ll look slightly underbaked, but that’s exactly right.
Not using enough marshmallows: I know it seems like a lot, but 2 cups of mini marshmallows is the right amount. If you skimp on them, you won’t get that gooey, s’more-like texture that makes this dessert special.
Skipping the graham cracker topping: Don’t do it. The graham cracker crumbles add texture, flavor, and visual appeal. Plus, they toast slightly in the oven and become crispy and delicious.
Using cold batter: If your batter has been sitting out for a while, it might be too thick to press into the skillet. If this happens, just warm it up slightly in the microwave for 10 to 15 seconds, and it’ll be easier to work with.
My Tested Substitutions
I’ve made this recipe dozens of times, and I’ve tried just about every substitution imaginable. Here’s what actually works:
Homemade cookie dough instead of brownie mix: Use your favorite chocolate chip cookie recipe. You’ll need about 1.5 to 2 cups of dough. Press it into the skillet and bake at 350°F for about 15 minutes before adding the marshmallows and graham crackers. The result is a bit less fudgy than the brownie mix version, but it’s delicious and feels more homemade.
Different types of chocolate chips: I’ve used semi-sweet, dark, milk, and even white chocolate chips. They all work, but semi-sweet is my favorite because it balances the sweetness of the marshmallows and graham crackers.
Regular marshmallows instead of mini: Cut them in half with kitchen scissors (spray the scissors with cooking spray so they don’t stick). They work fine, but they don’t distribute as evenly, and some pieces will be more toasted than others.
Honey graham crackers: If you prefer honey graham crackers to regular, absolutely use them. The flavor is slightly sweeter and more complex.
Gluten-free brownie mix: This works perfectly. The texture is virtually identical to regular brownie mix.
How to Customize This Recipe
The beauty of this s’more cookie skillet is that it’s incredibly flexible. Here are some ways to make it your own:
Make it smaller: If you’re cooking for just one or two people, use an 8-inch cast iron skillet instead of a 10-inch, and cut the recipe in half. The baking time will be slightly shorter, so check for doneness around the 12-minute mark.
Make it bigger: If you’re feeding a crowd, use a 12-inch skillet or a 9×13-inch baking dish. You’ll need to increase the recipe by about 50 percent. Bake for 20 to 25 minutes before adding the marshmallows.
Add nuts: Sprinkle chopped pecans or walnuts over the chocolate layer before adding marshmallows. They add a nice crunch and richness.
Use different mix-ins: Instead of chocolate chips, try crushed candy bars, toffee bits, or even crushed pretzels mixed into the batter.
Serving Suggestions
This s’more cookie skillet is delicious on its own, but here are some ways to make it even more special:
With vanilla ice cream: A scoop of vanilla ice cream on top of a warm slice is absolutely heavenly. The ice cream melts into the warm chocolate and marshmallows, creating this incredible gooey mess that’s pure comfort.
With whipped cream: A dollop of whipped cream adds a light, airy contrast to the rich, gooey cookie.
With a drizzle of chocolate sauce: If you want to go full chocolate mode, drizzle some warm chocolate sauce over the top.
With coffee: This dessert pairs beautifully with a cup of hot coffee or a cold glass of milk. The chocolate and marshmallows complement both perfectly.
Straight from the skillet: My favorite way to serve this is straight from the skillet with a spoon, family-style. Everyone gathers around and digs in. It feels casual and fun and delicious.
Meal Prep and Storage
This s’more cookie skillet is best eaten warm, within a few hours of baking. That said, here’s how to store it if you have leftovers:
Room temperature: Cover the skillet loosely with foil and leave it on the counter for up to 4 hours. The marshmallows will firm up as it cools, but it’ll still be delicious.
Refrigerator: Cover with plastic wrap and refrigerate for up to 2 days. Reheat in a 300°F oven for about 10 minutes to warm it through and soften the marshmallows slightly.
Make ahead: You can prepare the brownie batter and press it into the skillet up to 24 hours ahead. Cover with plastic wrap and refrigerate. When you’re ready to bake, just add a few extra minutes to the baking time since the batter will be cold. Don’t add the marshmallows and graham crackers until the last 5 to 7 minutes of baking.
Freezing: This doesn’t freeze particularly well because the marshmallows get tough and the texture changes. I’d recommend making it fresh when you want it.

Frequently Asked Questions
Q: Can I make this s’more cookie skillet without a cast iron skillet?
A: Absolutely. You can use an 8 or 9-inch round cake pan, pie dish, or even a square baking dish. The baking time might vary slightly depending on the depth and material, so check for doneness around the 20-minute mark. Cast iron just holds heat beautifully and gives you those crispy edges, but any oven-safe dish works.
Q: How do I know when the cookie skillet is done baking?
A: The edges should be set and lightly golden, but the center will still look slightly underbaked—that’s exactly what you want. The cookie will continue to cook as it cools, and you’ll get that perfect chewy center with crispy edges. If you overbake it, the marshmallows will deflate and the cookie becomes too firm.
Q: Can I prepare this ahead of time?
A: You can mix the cookie dough up to 24 hours ahead and refrigerate it. Press it into your skillet, cover with plastic wrap, and bake when ready. Don’t add the marshmallows and graham crackers until the last 5 minutes of baking, or they’ll brown too much. This makes it perfect for entertaining.
Q: What’s the best way to serve this s’more cookie skillet?
A: Serve it warm, straight from the skillet if possible. A scoop of vanilla ice cream on top melts beautifully into the warm chocolate. You can also let it cool for 5 minutes and cut into wedges. It’s best eaten within a few hours of baking while the marshmallows are still soft and gooey.
Q: Can I use homemade cookie dough instead of a box mix?
A: Yes, use your favorite chocolate chip cookie dough recipe. You’ll need about 1.5 to 2 cups of dough. Press it into the skillet and bake at 350°F for about 15 minutes before adding the marshmallows and graham crackers. Homemade dough works beautifully and gives you more control over the flavor.
