Revolutionize your summer dessert game with these incredibly easy 3-ingredient S’moreos! Whether you’re gathered around a roaring campfire or cozying up indoors, these gooey, chocolate-stuffed treats can be made in the oven, ensuring you can indulge in their deliciousness any time the craving strikes.

Irresistible S’moreos: Your Ultimate Guide to Stuffed Oreo S’mores
Welcome to your next dessert obsession – S’moreos! These aren’t just any ordinary cookies; they’re a delightful fusion of classic s’mores and everyone’s favorite sandwich cookie. Imagine a perfectly toasted marshmallow and rich melted chocolate, all embraced within two crispy Oreo halves. The result? An ooey-gooey, utterly satisfying treat that takes minimal effort to create but delivers maximum joy. Originally a camping staple, we quickly discovered these wonders could be enjoyed right in our kitchen using the broiler, making them a year-round indulgence.
The beauty of S’moreos lies in their versatility. While the warmth of a campfire enhances the outdoor experience, the convenience of an oven means you’re never more than a few minutes away from a warm, chocolatey, marshmallow-filled delight. They’re perfect for spontaneous dessert cravings, last-minute gatherings, or simply elevating a quiet evening at home. Even when we recently celebrated Wally’s fifth birthday by the lake – where fires weren’t permitted – we made sure to pack a batch of these delectable treats. They hold up beautifully and are just as delicious after they’ve cooled a bit, making them ideal for picnics and packed lunches too.
What Exactly Are S’moreos and Why You Need Them
At their core, S’moreos are a clever twist on the traditional s’more. Instead of graham crackers, we use Oreo cookies to sandwich the toasted marshmallow and melted chocolate. This simple substitution transforms the classic campfire treat into something uniquely delicious and even more accessible. The crisp chocolate cookie provides a perfect textural contrast to the soft, gooey marshmallow and creamy chocolate. It’s a nostalgic flavor combination that appeals to all ages, bridging the gap between a classic outdoor snack and a beloved pantry staple.
Beyond their incredible taste, S’moreos offer several advantages: they’re incredibly easy to make, require only three main ingredients, and produce less mess than traditional s’mores, especially when made in the oven. This makes them an ideal choice for busy parents, amateur bakers, or anyone looking for a quick and impressive dessert. Forget the sticky fingers and crumbling graham crackers – S’moreos offer a more contained, yet equally delightful, experience.

The Simplicity: Just Three Essential Ingredients
One of the most appealing aspects of S’moreos is the minimal ingredient list. You truly only need three delicious components to create these incredible Oreo s’mores. Quality ingredients will, of course, elevate your final product, but even with standard pantry items, these treats shine.
- Marshmallows: The star of any s’more! We recommend using regular-sized marshmallows. Jumbo marshmallows will be far too large for an Oreo, creating an overly messy situation. If you find even regular marshmallows a bit unruly or want a neater finish, you can easily cut them in half crosswise. This ensures they fit perfectly without too much overflow, though a little ooze is part of the fun!
- Oreo Cookies: The crunchy, chocolatey foundation. While any Oreo variety will work, I personally prefer using double-stuff Oreos. The extra cream filling adds another layer of sweetness and texture, complementing the melted chocolate and marshmallow beautifully. Don’t be afraid to experiment with flavored Oreos for exciting variations, which we’ll discuss later.
- Chocolate Chips: The melting magic! Initially, I experimented with a small square of milk chocolate, but I found that semi-sweet chocolate chips provided a more balanced flavor that wasn’t overly sweet. However, if you are a true milk chocolate aficionado, feel free to use your preferred chocolate. Chocolate chips are convenient because they melt easily and distribute well, but finely chopped chocolate bars work just as well.
Gather Your Gear: Essential Tools for S’moreo Success
To make S’moreos, you won’t need any specialized equipment. Most of what you need can be found in a standard kitchen, making this recipe even more approachable:
- Baking Sheet: A standard baking sheet is essential for the oven method.
- Parchment Paper: Crucial for preventing sticking and making cleanup a breeze. Don’t skip this!
- Spoon or Small Spatula: Useful for spreading the melted chocolate and helping to sandwich the cookies.
- Tongs or Fork (for campfire method): To safely roast marshmallows over an open flame.
- Airtight Container: For storing any leftover S’moreos.

Mastering the Art of S’moreos: Step-by-Step Instructions
Whether you choose the indoor oven method or the classic campfire approach, making S’moreos is straightforward. Let’s delve into both methods to ensure you can enjoy these treats anytime, anywhere.
Oven Method (Broiler): Quick and Convenient
The oven method is perfect for rainy days, urban settings, or when you simply want a quick dessert without the hassle of building a fire. The broiler provides intense, direct heat that toasts marshmallows beautifully and melts chocolate in mere minutes.
- Prepare Your Baking Sheet: First, line a baking sheet with parchment paper. This is a non-negotiable step, as melted marshmallow and chocolate can be incredibly sticky.
- Separate the Oreos: Carefully twist open about 10 Oreo cookies, aiming to keep the cream icing as intact as possible on one half of each cookie. Lay the separated Oreo halves face-up on your parchment-lined baking sheet.
- Add the Chocolate and Marshmallows: On the half of the Oreo that still has the cream icing, place 2-3 chocolate chips. On the other, un-iced Oreo half, place 4-5 chocolate chips. The extra chocolate on the non-iced side helps create a richer chocolate layer. Finally, place one regular-sized marshmallow on top of each frosted Oreo half. Remember our tip: if the marshmallow seems too large, cut it in half horizontally or place it vertically to better fit the cookie surface.
- Broil to Perfection: Place the entire tray in the oven on a middle rack. Turn your broiler to the ‘low’ setting. Broil for approximately 4-5 minutes, but here’s the crucial part: do not walk away! Marshmallows can go from perfectly golden to burnt in a matter of seconds. Keep a close eye on them until they are beautifully golden brown and puffy, and the chocolate chips are glistening and melted.
- Assemble and Serve: Once removed from the oven, the marshmallows will likely be puffed up impressively. They will gently shrink down after a minute or two. While still warm and gooey, use a small spoon or knife to gently spread the melted chocolate on the un-iced Oreo half. Then, carefully sandwich the two halves together, pressing gently until the marshmallow and chocolate meld into one irresistible unit. Serve immediately and enjoy the warm, gooey goodness!


Campfire Method: The Traditional Experience
There’s nothing quite like the smoky flavor and outdoor ambiance of a campfire s’more. S’moreos translate beautifully to this traditional setting, bringing a familiar taste with an exciting twist.
- Prepare Your Cookies and Chocolate: On a clean, separate serving surface (like a plate or a clean tray), arrange the separated Oreo halves. Place the chocolate chips on both the frosted and unfrosted halves, as instructed for the oven method. This ensures the chocolate is ready to melt when the hot marshmallow is added.
- Roast the Marshmallows: Using a roasting stick or skewer, carefully roast your marshmallows over an open flame until they are perfectly golden brown and soft throughout. Aim for a slow, even roast rather than setting them on fire for the best flavor and texture.
- Assemble by the Fire: Once the marshmallow is perfectly roasted and still piping hot, quickly place it on top of one of the chocolate-laden Oreo halves. Immediately place the other Oreo half (frosted side down) on top of the marshmallow, gently pressing to create your S’moreo. The heat from the marshmallow will quickly melt the chocolate, fusing everything together.
- Serve Warm: Enjoy your campfire S’moreos right away!
S’moreo Variations to Spark Your Creativity
The basic S’moreo recipe is fantastic on its own, but it also serves as a wonderful canvas for experimentation. Don’t be afraid to get creative and customize them to your taste!
- Flavored Oreos: The possibilities are endless! Imagine the cool burst of a mint Oreo paired with semi-sweet chocolate, or the rich delight of a peanut butter Oreo. Golden Oreos could be fantastic with white chocolate or even a caramel drizzle. Birthday Cake, Red Velvet, or even seasonal Oreo flavors could create truly unique S’moreos.
- Different Chocolates: Swap out semi-sweet chocolate chips for milk chocolate, dark chocolate, white chocolate, peanut butter chips, or even butterscotch chips. Each offers a distinct flavor profile that can completely change the character of your S’moreo. For a gourmet touch, try using high-quality chocolate squares, perhaps with a touch of sea salt.
- Add-Ins and Toppings: Before sandwiching the cookies, consider sprinkling a few mini chocolate candies (like M&M’s), crushed nuts, or a dash of cinnamon on the melted chocolate. After assembly, a light drizzle of caramel sauce, hot fudge, or even a sprinkle of flaky sea salt can take your S’moreos to the next level.
- Mini S’moreos: For bite-sized treats perfect for parties, use mini Oreos and mini marshmallows. Adjust cooking times accordingly.
Expert Tips for Perfect S’moreos Every Time
- Watch the Broiler Like a Hawk: This cannot be stressed enough. Marshmallows toast very quickly under a broiler. A minute too long can result in burnt, bitter marshmallows. Stay by the oven and pull them out as soon as they reach your desired golden-brown color.
- Marshmallow Placement: As mentioned, regular-sized marshmallows work best. If you find them too large, cutting them in half or placing them vertically on the Oreo half can help them fit more neatly and prevent excessive oozing.
- Preheat Your Broiler: Ensure your broiler is fully preheated before putting the tray in. This ensures even heat and quick results.
- Gentle Spreading: When spreading the melted chocolate on the un-iced Oreo half, be gentle. The cookie can be delicate, especially when warm.
- Serve Immediately: S’moreos are at their absolute best when served warm, right after assembly. The contrast of the crispy cookie with the warm, gooey filling is irresistible.
Beyond Oreos: Exploring Other Sandwich Cookie Delights
Absolutely! The S’moreo concept can be applied to almost any sandwich cookie. This is a fantastic way to experiment with different flavor combinations and textures. Imagine the possibilities with:
- Nutter Butters: For peanut butter lovers, Nutter Butter cookies would create an incredible peanut butter s’more hybrid. Pair with milk chocolate for a classic combo.
- Fudge Stripes: The crispy shortbread and pre-existing fudge stripes could add an interesting dimension.
- Other Chocolate Sandwich Cookies: Many brands offer their versions of chocolate sandwich cookies. Feel free to use your favorite!
- Graham Cracker Sandwiches: If you love the taste of a classic s’more but want a neater approach, try using small square graham crackers.
The key is to use a cookie that is sturdy enough to hold its shape when warm and provides a complementary flavor to the marshmallow and chocolate. Don’t be afraid to experiment with your favorite store-bought cookies!

Description
Switch your s’mores game up this summer with these 3 ingredient s’moreos! You can even make them inside the oven so you can enjoy them any time!
Ingredients
- 10 double-stuff Oreos (or regular Oreos)
- 1/4 cup chocolate chips (semi-sweet or your preferred type)
- 10 regular-sized marshmallows*
Instructions
- Separate the Oreos in half, keeping the icing on one side as much as possible. Lay out the open Oreos on a parchment-lined baking sheet. Add about 3 chocolate chips on the frosted side, and about 5 chocolate chips on the un-frosted side. Add a marshmallow on top of each of the frosted side.
- Place the baking tray under the broiler in the oven turned to low. Broil for 4-5 minutes or until the marshmallows are golden and toasty and the chocolate chips are melted. Keep a close eye on them as they can burn quickly. Remove the tray from the oven and place the two halves together. Serve immediately!
If you don’t finish the S’moreos while warm, you can save them for later. Keep them at room temperature in an airtight container for up to 3 days.
Notes
- *If the marshmallows seem way too big for the Oreos, cut them in half. A giant oozy marshmallow is delicious but it won’t be as pretty!
- **Try placing the marshmallows vertically on top of the Oreo half instead of horizontally to have it fit nicer on the small cookie.
