I burned the edges of my first skillet cookie three times before realizing that patience is the real secret ingredient here. Honestly, I never thought I’d be the type to obsess over a skillet cookie stuffed with s’mores, especially since I usually prefer my desserts neat, not messy. But that gooey, melty marshmallow center sneaking out from the cookie’s warm embrace? That’s a different story. It took a few tries—some smoke alarms, a couple of “too crunchy” verdicts, and a handful of almost-right batches—to get this gooey s’mores stuffed skillet cookie just right.
The smell alone is a little dangerous: browned butter mingling with melting chocolate and toasted marshmallow aroma filling the kitchen. One evening, I pulled it out of the oven just in time to catch that perfect oozy moment before the marshmallows hardened again. Sitting there with a fork, the gooey mess was totally worth the trial and error. I never look at s’mores the same way now—this skillet cookie became my go-to comfort fix that’s ridiculously easy to whip up whenever I need a sweet boost.
What really stuck with me is how this recipe feels like campfire nostalgia wrapped into a warm dessert, yet it’s made right in your kitchen in under an hour. It’s not just about the cookie or the marshmallow—it’s the way it all comes together in one skillet, ready to share (or not). Sometimes the best recipes come from messing up a few times, and this one’s a keeper because it’s all about that gooey, chocolatey, toasty-sweet moment that you keep chasing. I’m pretty sure once you try this recipe, it’ll hold a similar spot in your heart (and stomach) as it does in mine.

- Quick & Easy: Ready in about 45 minutes, this recipe fits perfectly into a busy evening or last-minute craving fix.

It’s the kind of treat that makes you pause and savor—closing your eyes after the first bite isn’t uncommon around here. And if you’re into desserts that feel both nostalgic and a little bit fancy, this skillet cookie is the sweet spot.

What Ingredients You Will Need
This recipe uses simple, wholesome ingredients to deliver that bold flavor and satisfying texture without any complicated steps. Most of these are probably in your pantry already, which I love because it means no last-minute grocery runs!
- Unsalted butter, 1/2 cup (115g), browned and cooled (adds rich, nutty flavor)
- Light brown sugar, 3/4 cup (150g), packed (for that chewy sweetness)
- Granulated sugar, 1/4 cup (50g)
- Large egg, room temperature (helps bind everything together)
- Pure vanilla extract, 1 teaspoon (for aroma)
- All-purpose flour, 1 cup (125g), sifted (for structure)
- Baking soda, 1/2 teaspoon (leavening agent)
- Salt, 1/4 teaspoon (balances sweetness)
- Mini marshmallows, 1 cup (about 50g) (the gooey star of the show)
- Chocolate chips or chunks, 3/4 cup (130g), semi-sweet or milk chocolate (melts nicely for gooey pockets)
If you want to switch things up, almond flour works well for a gluten-free version, though the texture changes a bit (a bit denser but still tasty). You can also swap the mini marshmallows for regular ones cut into smaller pieces if that’s what you have on hand.
I often reach for Ghirardelli chocolate chips here because they melt smoothly and have a rich flavor, but any quality chocolate works. For the butter, don’t rush the browning process—it’s the key to giving this cookie that deep, almost caramel undertone.
Equipment Needed
- 10-inch cast iron or oven-safe skillet (a non-stick skillet can work, but cast iron gives the best crust)
- Mixing bowls (one large for the batter)
- Whisk or electric mixer (to cream the sugars and butter)
- Measuring cups and spoons (accuracy matters here!)
- Rubber spatula (for folding ingredients gently)
- Cooling rack (to let the skillet cookie rest a bit after baking)
If you don’t have a cast iron skillet, a heavy oven-safe pan or even a pie dish can substitute, but the texture might differ slightly. I’ve tried baking this in a silicone round pan, but the edges don’t crisp up as well. Cleaning your cast iron after baking? I recommend wiping with a little oil and avoiding soap to keep the seasoning intact.
Preparation Method

- Preheat the oven to 350°F (175°C). Place your cast iron skillet in the oven while it heats up (this helps start the crust formation).
- Browning the butter: In a small saucepan, melt 1/2 cup (115g) unsalted butter over medium heat. Stir constantly until it foams and then turns golden brown with a nutty aroma, about 5 minutes. Remove from heat and let cool for 5 minutes.
- Mix sugars and butter: In a large bowl, combine 3/4 cup (150g) light brown sugar and 1/4 cup (50g) granulated sugar. Pour in the browned butter and whisk until smooth and glossy.
- Add egg and vanilla: Beat in 1 large egg and 1 teaspoon vanilla extract until fully incorporated.
- Combine dry ingredients: In a separate bowl, whisk together 1 cup (125g) all-purpose flour, 1/2 teaspoon baking soda, and 1/4 teaspoon salt.
- Mix dry into wet: Gradually fold the dry ingredients into the wet batter with a spatula, just until combined—don’t overmix or the cookie might get tough.
- Add chocolate chips: Fold in 1/2 cup (about 85g) of the chocolate chips gently.
- Prepare skillet: Carefully remove the hot skillet from the oven (use oven mitts!). Lightly grease it with butter or non-stick spray.
- Layer the batter: Spread half of the cookie dough evenly in the skillet. Sprinkle 1 cup mini marshmallows and 1/4 cup (about 45g) remaining chocolate chips evenly over the dough. Top with the remaining dough and gently spread it to cover the filling.
- Bake: Place skillet back in the oven and bake for 25-30 minutes. The edges should be golden and firm, but the center should still look a bit soft and jiggly (that’s the gooey magic!).
- Cool briefly: Let the skillet cookie cool for 5-10 minutes on a rack before digging in. This helps the marshmallow filling settle without losing the gooey texture.
If the edges brown too quickly, loosely tent the skillet with foil halfway through baking. When you cut into it, you want stringy marshmallow pulls and melted chocolate pockets—if it’s too firm, you baked it too long!
Cooking Tips & Techniques
One of the trickiest parts of making the ultimate gooey s’mores stuffed skillet cookie is balancing baking time. Too short, and the dough is raw; too long, and the marshmallows harden. I’ve learned to rely on visual cues rather than just the timer. When the edges are golden and pulling slightly away from the skillet but the center jiggles gently when nudged, that’s your sweet spot.
Browning the butter adds a toasty depth that plain melted butter can’t match—don’t rush this step. It’s worth standing over the stove watching that foam turn a rich amber color. Also, folding in the chocolate chips gently keeps the dough light and chewy.
Using a cast iron skillet helps create a crispy edge, which contrasts beautifully with the soft, gooey center. If you’re using a different pan, expect a slightly different texture but still delicious results.
Resist the urge to dig in right away! The cooling time lets the marshmallows thicken just enough so they don’t run everywhere but remain delectably soft. If you’re impatient like me, a quick tip is to serve with a scoop of vanilla ice cream to cool the gooey mess as you eat.
Variations & Adaptations
- Peanut Butter Twist: Swirl 1/4 cup creamy peanut butter into the batter before baking for a nutty flavor that pairs wonderfully with chocolate and marshmallow.
- Seasonal Berry Boost: Add fresh or frozen raspberries or strawberries (about 1/2 cup) into the middle layer along with marshmallows for a tart contrast. Perfect for summer, similar to the fresh fruit approach in the patriotic strawberry shortcake skewers.
- Vegan Version: Substitute vegan butter and use dairy-free chocolate chips plus vegan marshmallows to make this treat plant-based. The texture will be slightly different but still satisfying.
- Salted Caramel Drizzle: After baking, drizzle with warm salted caramel sauce for an extra layer of indulgence reminiscent of the salted caramel apple oat bars from this kitchen.
I once tried adding chopped toasted pecans to the top for a crunchy finish, and that was a winner for texture lovers. Feel free to customize based on what you have or what you’re craving.
Serving & Storage Suggestions
This skillet cookie is best served warm for maximum gooey impact. I like to scoop generous portions straight from the skillet, with a side of vanilla ice cream or whipped cream to cool down the heat and complement the sweetness. It also pairs surprisingly well with a cup of strong coffee or a cold glass of milk.
Leftovers (if there are any!) can be stored in the skillet or an airtight container at room temperature for up to 2 days. For longer storage, wrap tightly and freeze up to 3 months—reheat gently in the oven at 300°F (150°C) for 10-12 minutes to restore that melty texture.
Interestingly, the flavors meld and deepen if you let it sit overnight, but the gooey marshmallow softens, so I prefer it fresh or reheated just right. This skillet cookie makes a perfect dessert to bring to parties or casual get-togethers, especially when you want to impress without fuss.

Frequently Asked Questions
Can I use regular-sized marshmallows instead of mini ones?
Yes, but cut them into smaller pieces so they melt evenly and don’t create large pockets. Mini marshmallows give the best gooey texture throughout.
What if I don’t have a cast iron skillet? Can I use a regular baking pan?
You can use an oven-safe round pan or pie dish, but the cookie edges won’t crisp up as much. The texture will still be deliciously gooey in the center.
How do I know when the skillet cookie is done baking?
Look for golden edges that pull away slightly from the skillet and a center that still jiggles gently. If the center is firm, it’s probably overbaked and the marshmallows will be less gooey.
Can I prepare this skillet cookie ahead of time?
You can assemble the dough and layer the skillet ahead, then refrigerate for up to 24 hours before baking. Just add a couple extra minutes to the baking time if baking cold.
Is this recipe suitable for gluten-free diets?
Yes, by swapping all-purpose flour for almond flour or a gluten-free blend, you can make a gluten-free version. Texture may vary slightly but the gooey s’mores flavor remains.
