These S’more Brownies are layered with graham crackers and marshmallows and smothered with brownie mix! Then, just when you thought we were done, we added a layer of Oreo Cookies to give it just a bit extra chocolate yumminess!

S’mores Brownie aka S’mOreo Brownie Bars

I’m not sure exactly what it is about s’mores that I love so much. It could be the warm and gooey marshmallows or possibly the melted chocolate. Honestly though, I think it is just that it reminds me so much of warm summer nights out in our backyard just hanging out with our neighbors.

What I adore about these S’moreo brownies, is that they can be enjoyed all year round…no campfire needed. I can get that taste of summer in the dead of winter!

Ingredients:

  • Graham crackers
  • Oreo cookies – I used mini Oreos (you can leave out the Oreos if you choose, but that would be just silly)
  • Marshmallow – I fell in love with the flat s’more marshmallows
  • Brownie mix (pick your favorite)

steps to make s'more brownies

How to Make S’more Brownies (stuffed with Oreos!)

  1. Preheat oven to 325 degrees
  2. Prepare brownie mix according to the directions on your box
  3. Line a 9 x 13 glass baking dish with parchment paper
  4. Lay graham crackers all along the bottom of the dish
  5. Using a spatula, spread a layer of the brownie mix over the graham crackers – covering as much of the crackers as possible
  6. Place a layer of Oreo cookies on top of the brownie layer
  7. Layer the marshmallows over the top of the cookies (I used the flat s’more marshmallows – but I cut them each in half so there was a thin layer of marshmallow cutting marshmallow in half
  8. Use the remaining brownie batter to cover the marshmallows and along the sides of the Oreo cookies – spread it as evenly as possible.
  9. Bake for 45 minutes (this may vary depending on your oven – check around 35 minutes to see if they are done. Personally, I prefer them a little overcooked than undercooked).
  10. Take out of oven and place a layer of marshmallow on top of the brownies (again, I cut my in half). Place them under the broiler until they start to get golden brown –
    IMPORTANT NOTE: Do not take your eyes off of them, they burn really, really fast. The longest you will need to leave them is 2 minutes.
  11. Let them cool completely before cutting – otherwise you will have a huge mess on your hands! I left mine for about 2 hours before I cut them!
  12. Enjoy!

Jenn’s Notes

IMPORTANT NOTE: Do not take your eyes off of them, they burn really, really fast. The longest you will need to leave them is 2 minutes, but probably less.
TIP: To cut your s’more brownies let them cool completely and spray a knife with cooking spray and cut.

  1. Omg, omg, omg! I want these right now. Like for breakfast! I can’t wait to make these for our family get together this weekend!! Thanks for the recipe…sharing on FB this morning 🙂

    1. Jenna – I want to bottle you up and bring you home! I love finding someone as enthusiastic about a dessert as me! I have been running around all week saying “OMG S’mOreos OMG!!!!

    1. Hi Candy – You bake the layers with the final layer being the brownies – when those are done, you take them out of the oven and put an additional marshmallow layer on top and broil that for about 1-2 minutes (until golden brown). Hope that makes more sense!

  2. This looks so good! I’m not much of a baker but I might be willing to give it a try for this recipe, or maybe just ask someone else to make it for me 🙂

  3. These were horrible, we double and triple check the recipe, and the brownie once too. The marshmallows were burnt so bad you couldn’t even eat the top, the brownie battery didn’t even finish cooking. So I don’t know where you got that picture, or you write down the direction incorrectly. So disappointed.

    1. So sorry they didn’t work out for you…. the recipes is correct and they were delicious here! As I mentioned, the top marshmallows only go on at the very end and you just want them browned. Different ovens cook differently, so 2 minutes may be too long for some, that is why you need to watch them and take them out as soon as they begin to brown. However, I guarantee the picture is actually mine and they are a family favorite in my house 🙂

  4. I just made these last night. How did you store them? I made them in advance for a party this weekend. Can I just cover and leave out? I’m afraid if I refrigerate or freeze the graham cracker will get mushy or the marshmallows won’t be the same.

  5. I made this twice. Followed the recipe to a ‘T’. Both times it was hard as a rock. Especially around the edges. Any suggestions?

  6. These did not come out well at all. I’m a seasoned baker and these were burnt on top (not talking about the marshmallows, i added them last) and not done in the middle. Its too thick. I followed directions and my oven is fine. I usually don’t leave reviews but I wish I would’ve read the others before I made this.

    1. So sorry they didn’t come out for you! Not sure what happened. What type of pan did you use? 9×13 glass??

  7. Hi, I’m going to try to make these for a party this weekend(my niece requested me to make something to do with s’mores for desert) but I was wondering have you ever tried or what do you think about putting graham cracker crumbs on top of marshmallows before you put them under broiler? Thanks!

  8. How do you know when they’re done baking? Will a toothpick actually come out clean like with regular brownies?

    1. Unfortunately, not really. Because the Oreo’s get melty and never really “cook firmly”. Mine were around the same time as it stated on the box of brownie mix. I would err on the side of overcooking a bit, but that is just me!

  9. I’ve made these several times and they’ve come out perfectly. They’re a gooey mess-just how brownies should be!
