Oreo S’mores Bars
Who doesn’t love s’mores? Oreo S’mores Bars put a delicious twist on the classic with Oreos, gooey marshmallows, and plenty of chocolate in every bite!
S’mores get a fun upgrade in this easy Oreo S’mores Bars recipe! Double Stuf Oreos add extra chocolatey flavor and crunch, while gooey marshmallows bring all that classic s’mores goodness. Best of all, there’s no campfire needed—these irresistible bars are made right in your oven.
Unlike traditional handheld s’mores, these s’mores are layered and baked in a 9×13-inch baking dish. They’re fun and easy to assemble, so get the kids involved!

Leftovers are delicious, too—just warm them in the oven for a few minutes to bring back that melty chocolate and marshmallow goodness.
What are Oreo S’Mores Bars?

Ingredients to make Oreo S’Mores
- Graham crackers
- Double Stuffed Oreo Cookies
- Sugar – White granulated sugar.
- Salt – Just a pinch.
- Butter – Unsalted; melted.
- Hershey chocolate bars – 7-8 regular or 3 extra-large bars
- Jumbo marshmallows
How to make S’Mores Bars with Oreos
- Preheat your oven to 400-F and lightly grease a 9×13-inch baking dish with nonstick spray. Then, line it with parchment paper so that the paper hangs over the sides a bit. Set the pan aside.
- Twist the Oreo cookies apart. Divide them, adding the half with NO cream to the food processor. Add the graham crackers to the food processor with the creamless cookie halves and pulse until finely ground.
- Transfer the ground cookies to a bowl and add the sugar and salt. Stir to combine.
- Add the melted butter to the ground cookies and mix well. Transfer the buttered crumbs to the baking dish and press down gently with your fingers or an offset spatula to form the crust.
- Bake the crust for 8-10 minutes or until the edges are lightly golden. Remove from the oven and allow to cook for 5-8 minutes.
- Unwrap the chocolate bars and lay them on top of the crust layer, leaving about ¼-inch around the edges uncovered.
- Arrange the remaining Oreo halves, cream side up, on top of the chocolate bars.
- Add the marshmallows to the top of the cookie halves. Don’t worry about covering the whole dish – the marshmallows will expand as they bake.
- Bake for 10-12 minutes or until the chocolate is soft and the marshmallows are golden brown on top.
- Slice and serve immediately for gooey bars, or allow the bars to cool for at least 20 minutes, then slice and serve for a firmer Oreo S’more bar. Enjoy!
Sandy’s tips and substitutions:
- Prep ahead: Assemble the Oreo S’Mores Bars earlier in the day, then leave them at room temperature until you’re ready to bake and serve.
- Use classic Hershey’s bars: Plain Hershey’s milk chocolate bars melt beautifully, but any favorite plain chocolate bar will work.
- Double Stuf Oreos are best: Regular Oreos work, but Double Stuf add extra creamy, gooey goodness.
- Stock up when they’re on sale: The ingredients are pantry-friendly, so keep them on hand for an easy last-minute summer dessert.
- STORAGE: Store any leftovers in an airtight container on the counter for 2-3 days.
Serving
This is such a fun and tasty dessert recipe that everyone always loves! It makes a fairly big pan, and I love serving them when we’re having family and friends over for cookouts and summer BBQ dinner parties. They pair well with Hawaiian Teriyaki Chicken, grilled brats, and of course, juicy burgers. I’ll also put out strawberry lemonade for the kids and Summer Sangria for the adults.

Oreo S’mores Bars
Ingredients
Crust:
- 12 graham crackers
- 24 Double Stuffed Oreo Cookies
- ¼ cup granulated sugar
- Pinch salt
- 8 tablespoons unsalted butter, melted
Topping:
- 11 ounces extra-large Hershey bars, buy the XL ones, or 7-8 regular-size ones
- 24 jumbo marshmallows
Equipment
Instructions
- Preheat the oven to 400°F. Lightly grease a 9-by-13-inch baking pan with nonstick spray. Next, line the pan with parchment paper, allowing parchment to hang over the edges.
- CRUST: Twist the tops off the Oreo cookies. Set aside the bottoms (with the cream).
- In a food processor, add the Oreo cookie tops and the graham crackers; pulse until finely ground.
- Transfer the graham cracker/Oreo cookie crumbs to a medium bowl. Add the sugar and salt to the graham-cracker crumbs and stir to combine. Add the melted butter and stir. Pour the mixture into the prepared 9×13 pan. Press the crust with your fingers, to make an even layer.
- Bake for 8 to 10 minutes, or until the edges are lightly golden. Remove from oven and allow to cool for 5-8 minutes.
- TOPPING: On top of the crust, lay down the chocolate bars, leaving about ¼ inch of crust uncovered around the edges. Next, arrange the 24 cookie bottoms, cream-side up, on top of the chocolate bars. Place the marshmallows on top of the Oreo cookie bottoms. The marshmallows will increase in size as they bake.
- Bake for 10-12 minutes, or until the chocolate is soft and the marshmallows are golden brown on top.
- Serving gooey bars: Slice and serve immediately.
- Serving firm bars: Allow the bars to cool when removing from the oven, for at least 20 minutes.
- If serving later, reheat individual servings for a gooey experience!
