Honestly, these cookies are what campfire dreams are made of, but you don’t even have to leave your kitchen.

I first whipped up this recipe on a rainy weekend with my kids, desperately craving that classic s’mores flavor but unwilling to brave the soggy backyard. After a few tweaks—adding extra chocolate chunks here, toasting marshmallows there, and fiddling with the dough—these cookies became one of our family’s most-requested treats. I love how they bring a bit of nostalgia, a ton of comfort, and maximum chocolate satisfaction all at once.

Whether you need an easy dessert for a party, want to surprise the kids after school, or just need a pick-me-up with your afternoon coffee, these double chocolate chunk s’mores cookies totally deliver. They’re perfect for anyone with a serious sweet tooth, chocoholics, and anyone who just wants to relive a little summer magic any time of year. Trust me—I’ve baked these more times than I can count, and they never, ever disappoint!

Why You’ll Love This Recipe

Let’s get real—there are a million cookie recipes out there, but these Double Chocolate Chunk S’mores Cookies stand out in all the right ways. Here’s why you’ll find yourself coming back to them again and again:

• Quick & Easy: These come together in under 30 minutes with no chilling required—so you can satisfy your cravings fast (and who has time to wait for cookie dough to rest, anyway?).
• Simple Ingredients: You probably have everything you need right in your pantry. No fancy chocolate or hard-to-find marshmallows—just classic, delicious basics.
• Perfect for Any Occasion: Great for bake sales, potlucks, cozy movie nights, or even gifting during the holidays. I’ve even packed them in lunchboxes for a surprise treat!
• Crowd-Pleaser: I’ve tested these on picky kids, chocolate-snob adults, and everyone in between. Every single time, they disappear almost as soon as they hit the plate.
• Unbelievably Delicious: The combination of fudgy chocolate cookie, gooey marshmallow, and crunchy graham cracker is dangerously addictive. One is never enough!

What really makes these cookies different? It’s the double chocolate base—both cocoa powder and big chocolate chunks, so every bite is rich and gooey. I use mini marshmallows for those perfect melty pockets and real graham cracker pieces for that classic s’mores flavor. After years of testing, I’ve figured out how to keep the marshmallows from disappearing (trust me, I’ve had a few marshmallow-less batches!). This isn’t just another s’mores cookie recipe—this one is the ultimate.

But more than that, these cookies are pure comfort. They’re the kind of treat that makes you pause, smile, and maybe even sneak a second (or third). Whether you’re sharing them or keeping the batch for yourself, you’ll taste a little bit of summer, some serious chocolate, and a whole lot of joy.

What Ingredients You Will Need

This recipe uses easy-to-find, classic ingredients that work together to create that unforgettable double chocolate chunk s’mores cookie experience. Here’s what you’ll need (and a few tips along the way):

• For the Cookie Dough:
• Unsalted butter, softened (1/2 cup / 113g) – Room temperature butter makes for the best creamy texture. I like to use Kerrygold for extra richness, but any good butter works.
• Brown sugar (1/2 cup / 100g) – Adds moisture and a hint of caramel flavor.
• Granulated sugar (1/2 cup / 100g) – Balances the brown sugar and keeps the cookies chewy.
• Large eggs (2, room temperature) – Helps bind everything together and adds richness.
• Pure vanilla extract (2 tsp) – For that classic cookie aroma.
• All-purpose flour (1 3/4 cups / 220g) – You can use a good gluten-free blend if you need to!
• Unsweetened cocoa powder (1/2 cup / 45g) – Dutch process cocoa gives a deeper chocolate flavor, but natural works too.
• Baking soda (1 tsp) – Helps the cookies rise just the right amount.
• Salt (1/2 tsp) – Don’t skip it—it makes the chocolate pop.
• The Mix-Ins:
• Semi-sweet chocolate chunks (1 cup / 170g) – I love using a mix of chunks and chips (Ghirardelli is my go-to), but feel free to use all chips or even chopped chocolate bars.
• Mini marshmallows (1 cup / 50g) – These melt just right into gooey pockets throughout the cookie. If you only have large ones, just chop them up a bit.
• Graham crackers, roughly broken (1 cup / about 5 sheets / 50g) – Adds that classic s’mores crunch and flavor.

Substitution Tips: If you’re dairy-free, swap the butter for vegan margarine and use dairy-free chocolate chunks. For gluten-free cookies, use a 1:1 gluten-free flour blend and gluten-free graham crackers. No mini marshmallows? Chop up regular ones or try vegan marshmallows for an allergy-friendly twist.

You don’t need any hard-to-find ingredients for these Double Chocolate Chunk S’mores Cookies—they’re simple, honest, and just downright delicious. Sometimes, the best comfort food is the easiest to make!

Equipment Needed

• Mixing bowls: One large for the dough, one medium for dry ingredients. If you’re like me and hate extra dishes, you can get away with one bowl—but the two-bowl method guarantees even mixing.
• Electric hand mixer or stand mixer: Makes creaming the butter and sugars fast and easy, but a sturdy whisk and some elbow grease work in a pinch (trust me, I’ve done it on vacation with just a fork!).
• Baking sheets: At least two, lined with parchment paper or silicone mats for easy cleanup and no sticking. I love my old, slightly warped sheets—they bake cookies perfectly every time!
• Cookie scoop (optional): For even portioning, but two spoons work just fine. If you bake cookies often, a scoop is a game-changer.
• Spatula: For scraping the bowl and folding in all those delicious mix-ins.
• Wire rack: For cooling the cookies quickly and evenly.

If you’re on a budget, skip the fancy gear and use what you have. Just be sure your baking sheets are clean and flat (warped ones can cause uneven baking, but I actually like the crispy edges they give sometimes!). For specialty gear like a stand mixer, regular hand beaters work just as well for this dough.

Tip: Keep your parchment paper or silicone mats in good shape by washing them with gentle soap and laying them flat to dry. They last forever and make cookie baking way less messy!

How to Make Double Chocolate Chunk S’mores Cookies

1. Preheat the oven: Set your oven to 350°F (175°C). Line two baking sheets with parchment paper or silicone baking mats for easy cleanup.
2. Mix the dry ingredients: In a medium bowl, whisk together 1 3/4 cups (220g) all-purpose flour, 1/2 cup (45g) unsweetened cocoa powder, 1 tsp baking soda, and 1/2 tsp salt. Set aside.
3. Cream the butter and sugars: In a large bowl, beat 1/2 cup (113g) softened unsalted butter, 1/2 cup (100g) brown sugar, and 1/2 cup (100g) granulated sugar together with a hand mixer or stand mixer until light and fluffy—about 2-3 minutes. (If your butter’s too cold, microwave it for 10 seconds, but don’t melt it!)
4. Add eggs and vanilla: Beat in 2 large eggs, one at a time, then add 2 tsp pure vanilla extract. Mix until smooth and creamy.
5. Combine wet and dry ingredients: Add the flour-cocoa mixture to the wet ingredients. Beat on low speed just until combined. The dough will be thick and a bit sticky—don’t overmix!
6. Fold in the mix-ins: Gently fold in 1 cup (170g) semi-sweet chocolate chunks, 1 cup (50g) mini marshmallows, and 1 cup (50g) roughly broken graham cracker pieces. Make sure everything is evenly distributed so you get a bit of everything in each cookie.
7. Portion the dough: Use a cookie scoop or two spoons to drop 2-tablespoon-sized balls of dough onto your prepared baking sheets, spacing them about 2 inches (5cm) apart. (If the dough feels too sticky, chill it for 10 minutes—it’ll make scooping easier.)
8. Bake: Bake for 9-11 minutes, or until the edges are set but the centers still look slightly underbaked. The marshmallows will puff and the cookies will spread slightly—don’t worry if they look a little rustic!
9. Shape and cool: When the cookies come out, use the edge of a spoon to gently nudge any runaway marshmallow or shape the cookies into perfect circles. Let them cool on the baking sheet for 5 minutes before transferring to a wire rack. They’ll firm up as they cool.
10. Enjoy: Serve warm for ultimate gooeyness, or let them cool completely for a chewy, fudgy bite.

Troubleshooting:

• If your marshmallows melt too much, try tucking them inside the dough balls instead of leaving them exposed.
• Flat cookies? Make sure your butter wasn’t melted and check that you measured your flour correctly (spoon and level, don’t scoop!).
• If you want thicker cookies, chill the dough for 20-30 minutes before baking.

Personal tip: Sometimes I pop a few extra chocolate chunks and marshmallows on top of each dough ball before baking. They look bakery-worthy and taste even better!

Cooking Tips & Techniques

After baking countless batches of double chocolate chunk s’mores cookies, I’ve picked up a few tricks that make all the difference:

• Room Temperature Ingredients: Always use room temperature butter and eggs. Cold ingredients can cause the dough to seize up and not mix evenly—I’ve learned this the hard way when in a rush.
• Don’t Overbake: The cookies should look slightly underdone in the center when you take them out. They’ll finish setting as they cool. Overbaked cookies will lose that gooey magic.
• Keep Marshmallows from Melting Away: Tuck them into the center of the dough balls, and don’t let too many touch the baking sheet. Otherwise, they’ll melt out and stick.
• Mix-Ins Last: Always add chocolate chunks, marshmallows, and graham crackers at the very end. If you mix too early, the grahams can get soggy and the marshmallows can break down.
• Batch Baking: If you’re baking more than one sheet at a time, rotate them halfway through to make sure every cookie bakes evenly. Trust me, my old oven used to burn the back row every time!
• Clean Tools, Happy Cookies: Wipe your cookie scoop with a little oil if the dough sticks. For hand mixing, a sturdy wooden spoon works wonders (and gives you a mini arm workout!).

It’s easy to get distracted (I’ve definitely forgotten to set timers before). Set a timer for the shortest baking time and check early—every oven is a little different. And don’t be afraid of a little imperfection—some of my best batches have been a bit lopsided or extra gooey. That’s part of the fun!

Variations & Adaptations

One of the best things about these double chocolate chunk s’mores cookies is how flexible they are. Here are a few fun ways you can make them your own:

• Gluten-Free: Swap in a 1:1 gluten-free flour blend and gluten-free graham crackers. The results are just as fudgy and delicious (I’ve made these for my gluten-free friends, and they’re always a hit).
• Dairy-Free: Use vegan butter and dairy-free chocolate chips or chunks. Dandies vegan marshmallows work great as a substitute for standard minis.
• Peanut Butter Chocolate S’mores: Add 1/2 cup (125g) creamy peanut butter to the dough for a nutty twist. You can also toss in peanut butter chips or swap half the chocolate for white chocolate chunks if you’re feeling wild.
• Seasonal Swaps: For a holiday vibe, add a pinch of cinnamon or pumpkin spice to the dough in the fall. Around Christmas, mix in crushed peppermint candies with the chocolate chunks.
• Campfire Style: If you want that “toasted” marshmallow flavor, place the cookies under the broiler for 30 seconds after baking. Just watch them closely—they can go from golden to burnt in a heartbeat (been there, done that!).

I once tried making a version with chopped caramel candies and a sprinkle of sea salt on top—absolute heaven! Don’t be afraid to experiment. You might just discover your new favorite cookie!

Serving & Storage Suggestions

These double chocolate chunk s’mores cookies are best served slightly warm, when the chocolate is still melty and the marshmallows are gooey. If you’re serving to a crowd, stack them on a rustic wooden board for that campfire vibe, or arrange them in a big cookie jar for classic cookie nostalgia.

Pair with a cold glass of milk, a mug of hot cocoa, or even a scoop of vanilla ice cream for the ultimate treat. They’re also amazing with coffee—honestly, breakfast cookies are a thing in my house!

Storage: Store cooled cookies in an airtight container at room temperature for up to 5 days. If you want to keep them longer, freeze in a zip-top bag for up to 2 months. To enjoy later, just pop a cookie in the microwave for 10-15 seconds for that fresh-from-the-oven gooeyness.

Flavor Tip: The chocolate flavor actually deepens after a day or two. If you can resist eating them all at once, you might find they’re even better the next day!

Frequently Asked Questions

Can I make double chocolate chunk s’mores cookies ahead of time?

Absolutely! You can prepare the dough up to 48 hours in advance and keep it in the fridge. Bake fresh when you’re ready, or freeze dough balls for quick cookies any time.

How do I keep the marshmallows from melting too much?

Tuck the marshmallows inside the dough balls and avoid placing them right on the baking sheet. This keeps them gooey inside the cookie instead of melting out.

Can I use regular-sized marshmallows?

Yes, just chop them into smaller pieces. I’ve done this in a pinch and it works just fine!

Do I need to chill the dough?

Not necessarily, but if you want thicker cookies or if your kitchen is really warm, chilling for 20-30 minutes can help the cookies hold their shape.

How should I store leftover cookies?

Keep them in an airtight container at room temperature for up to 5 days, or freeze for up to 2 months. Reheat for a few seconds in the microwave for that fresh-baked taste!
