Oreo S’mores Bars
Who doesn’t love s’mores? This chocolatey treat is adored by kids and adults alike, but this tasty twist puts a spin on the classic preparation by using Oreos. Oreo S’mores Bars are even more delicious than the original, and with plenty of ooey gooey chocolate and marshmallow, everyone will love this way of making them!
S’mores, the classic campfire treat of smooshing a toasty marshmallow between graham crackers and chocolate, get a fun twist in this tasty recipe. Here, we’re using double-stuffed Oreo cookies to add even more flavor and crunch to this awesome treat.
Oreo S’mores Bars
You don’t need a campfire for this recipe! These tasty s’mores are made in your oven. You will need a food processor to grind up the cookies, but this amazing dessert can be made from start to finish in your kitchen.
Instead of a hand-held treat, this dessert is more bar-like. It’s a layered dish built into a 9×13-inch baking dish. Get the kids to help you assemble this dish – it’s fun and easy to make!
You can serve these Oreo S’mores bars hot and gooey from the oven or let them cool and serve them once they’ve firmed up. They’re also easy to reheat – just pop them into the oven for a few minutes to warm up, and they’ll get all nice and gooey again.

Gather these ingredients

- Butter – Unsalted; melted.
- Hershey chocolate bars – 7-8 regular or 3 extra-large bars
- Jumbo marshmallows
How to make Oreo S’mores
- 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!
Tips & substitutions
- You can get this s’more dessert recipe ready for the oven and then bake it before serving. To do that, prepare the crust, then assemble the rest of the dish. Let it hang out on the counter until you’re ready to bake it and eat it.
- Plain Hersheys chocolate bars work best in this recipe, but any kind of plain chocolate bar will work.
- You can use regular Oreos, but the double-stuffed ones add extra gooeyness.
- These ingredients are all pantry stable, so buy them when they’re on sale and bake them when ready!
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.
Store any leftovers in an airtight container on the counter for 2-3 days.
