Ingredients You’ll Need
Creating these Oreo S’mores Cookies is surprisingly simple thanks to a handful of straightforward ingredients that each bring something special to the table. From the rich butter that guarantees tenderness, to the crunchy Oreos that add texture, every component is essential for that perfect bite.
- All-purpose flour: Provides structure and the classic cookie base that holds everything together beautifully.
- Granulated sugar: Adds sweetness and helps create that slight crunch on the cookie edges.
- Brown sugar: Brings moisture and a subtle caramel note enhancing the overall flavor.
- Baking soda: Ensures your cookies rise just enough to be soft and chewy without being cakey.
- Salt: Balances the sweetness and intensifies the chocolate and Oreo flavors.
- Unsalted butter (softened): The key to a rich, tender texture; be sure it’s softened for easy mixing.
- Egg: Binds the dough together while adding to the chewiness.
- Vanilla extract: Elevates the cookie’s flavor with warm, sweet aromatics.
- Oreo cookies (chopped): The star ingredient, providing bursts of chocolatey crunch in every bite.
- Mini marshmallows: Deliver that signature s’mores gooeyness inside the cookie.
- Semi-sweet chocolate chips: Melts to create pockets of chocolatey goodness complementing the Oreos and marshmallows.
How to Make Oreo S’mores Cookies
Step 1: Prepare Your Oven and Pans
Start by preheating your oven to 350°F (175°C) and get your baking sheets ready by lining them with parchment paper. This simple prep step ensures your cookies bake evenly and release effortlessly from the sheet.
Step 2: Cream Butter and Sugars
In a mixing bowl, combine softened butter with granulated and brown sugars. Beat until the mixture is light, fluffy, and creamy – this process incorporates air that’s crucial for tender cookies with just the right lift.
Step 3: Add Egg and Vanilla
Next, beat in the egg followed by vanilla extract until everything blends together smoothly. These ingredients add moisture, richness, and depth of flavor that are the foundation of any great cookie dough.
Step 4: Combine Dry Ingredients
In a separate bowl, whisk the all-purpose flour, baking soda, and salt. Gradually fold this dry mixture into your wet ingredients until just combined. Avoid overmixing here to keep your cookies soft and tender.
Step 5: Fold in the Oreo Pieces, Marshmallows, and Chocolate Chips
The magic happens when you gently fold in the chopped Oreos, mini marshmallows, and chocolate chips. Stir carefully so those mini marshmallows do not dissolve completely and the cookies get delightful bursts of texture and flavor in every bite.
Step 6: Scoop and Space Your Cookies
Scoop tablespoon-sized dollops of dough onto your prepared baking sheets. Keep them spaced at least two inches apart because these cookies will spread slightly and you don’t want them to merge together.
Step 7: Bake Until Perfectly Golden
Bake for 10-12 minutes until the edges start to turn golden but the centers remain soft and slightly underbaked. This is the sweet spot for that gooey, chewy cookie texture you crave. Let them cool a few minutes before moving to wire racks to cool completely.
How to Serve Oreo S’mores Cookies

Garnishes
Although these cookies are fabulous on their own, you can sprinkle a pinch of flaky sea salt on top before baking to boost the chocolate flavors and add a gourmet touch. Another fun idea is to drizzle melted chocolate over the cooled cookies for extra decadence and visual appeal.
Side Dishes
Pair your Oreo S’mores Cookies with a cold glass of milk or a mug of hot cocoa for that authentic s’mores experience. They also make a delightful companion to simple vanilla ice cream, turning your snack into a mini dessert celebration.
Creative Ways to Present
For gatherings, arrange Oreo S’mores Cookies on a rustic wooden board alongside clusters of mini marshmallows and broken Oreo pieces for an interactive treat display. You can even sandwich two cookies together with a scoop of marshmallow fluff or melted chocolate to make mini cookie s’mores that are irresistible.
Make Ahead and Storage
Storing Leftovers
Keep your Oreo S’mores Cookies fresh by storing them in an airtight container at room temperature. They will stay deliciously soft for up to five days, giving you plenty of time to savor every last one without losing that gooey charm.
Freezing
If you want to enjoy these cookies later, freeze them in a single layer on a baking sheet before transferring to a sealed freezer-safe container or bag. They can be frozen for up to 2 months and thawed at room temperature when you’re ready for a sweet treat.
Reheating
To revive the warm, melty feeling, pop a cookie in the microwave for about 10-15 seconds or warm it briefly in a preheated oven. This brings back that freshly baked softness, making each bite just as dreamy as the first.
FAQs
Can I use regular chocolate chips instead of semi-sweet?
Absolutely! You can swap semi-sweet chocolate chips with milk or dark chocolate chips depending on your sweetness preference. Each variety will bring a slightly different, but equally delicious flavor to your Oreo S’mores Cookies.
Do the marshmallows melt completely while baking?
They soften and become gooey but won’t completely melt away if you fold them in gently and don’t overbake. This creates delightful little pockets of marshmallow melt in every bite.
Can I make the dough ahead of time?
Yes, you can prepare the dough up to 24 hours in advance and keep it refrigerated. Chilling the dough also helps develop deeper flavors and prevents the cookies from spreading too much during baking.
What is the best way to chop Oreos for this recipe?
Using a knife, pulse in a food processor, or even crush with your hands for a rough chop. The key is to have a mix of small pieces and chunks to get that great Oreo texture throughout the cookies.
Are these cookies suitable for a campfire treat?
Definitely! Their s’mores-inspired flavors make Oreo S’mores Cookies a fantastic alternative if you want the taste of a campfire experience without the hassle of roasting marshmallows over a fire.
