S’more Brownies with Oreo Cookies

Our S’more Brownies with Oreos recipe is the most delicious mashup of my Slutty Brownies merged with my layered S’mores Lush Dessert and my S’mores in the Oven sandwiches. It’s an easy way to combine the nostalgia of an outdoor dessert with the comfort of an indoor indulgence.

Much like campfire classic, these oven-baked s mores brownies have a graham cracker base, with chocolate brownie batter and melted marshmallow in the middle. These brownie bars are made even better because they’re stuffed with Oreo cookies and covered with even more chocolate and toasted marshmallows on top.

When it’s too cold (or hot) outside for open flames, there’s no reason to miss the fireside fun – skip the stick (and the mess) and bake your brownies any time or season.

S’,oreo Ingredients

smore brownie ingredients.
  • Graham crackers: You can use honey graham crackers or chocolate graham crackers to create the crunchy base.
  • Oreo cookies: I used mini Oreos for this smore brownie recipe. Feel free to use full-size Oreos or leave them out altogether, but that would be just silly!
  • Marshmallows: You can use mini marshmallow, large marshmallows cut in half, or Jet-Puffed S’moreMallows. I fell in love with these flat s’more marshmallows!
  • Brownie mix plus the ingredients called for on the box (water, oil, and egg): You can use your favorite brand of brownie mix or make your own homemade brownie batter from scratch.

Serving Suggestions

This s’mores brownie recipe makes the ultimate summer slice! Because it serves 20, it’s perfect for feeding plenty of friends at backyard barbecues, potlucks, and parties. Plus, it’s easily made in a baking pan, so it’s portable.

Serve with a scoop of ice cream, a dollop of whipped cream, or a drizzle of chocolate sauce to make them even more decadent!

Tips & Variations

  • Prepare Your Pan: Make sure you use parchment paper to line your glass baking dish. It makes it so much easier to remove the bars and clean up a breeze.
  • Bake Your Bars: Baking time may vary depending on your oven. Check around 35 minutes to see if yours are done. Personally, I prefer them a little overcooked than undercooked.
  • Don’t Burn When Broiling: Do not take your eyes off of your s mores brownie bars when broiling the top marshmallows. They burn really, really fast! The longest you will need to leave them under the broiler is 2 minutes, but probably less.
  • Cool Before Cutting: To cut your s’more brownies, let them cool completely and spray a knife with cooking spray before cutting.
  • Use Other Oreos: While smores brownie bars are traditionally stuffed with classic or mini Oreos, that doesn’t mean you can’t get creative and give other flavors a try. S’mores, Red Velvet, Golden, or your other favorite flavors should taste great with this recipe.

Proper Storage

  • To Store: Leftovers can be stored in an airtight container at room temperature for up to 3 days or in the refrigerator for up to 5 days.
  • To Freeze: These brownies can be frozen for up to 3 months. I recommend cutting them into squares and placing in a freezer bag or freezer-safe container. Defrost on the countertop when you are ready to serve.

Instructions
 

  • Preheat oven to 325 degrees
  • Prepare brownie mix according to the directions on your box
  • Line a 9 x 13 glass baking dish with parchment paper
  • Lay graham crackers all along the bottom of the dish
  • Using a spatula, spread a layer of the brownie mix over the graham crackers – covering as much of the crackers as possible
  • Place a layer of Oreo cookies on top of the brownie layer
  • 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
  • Use the remaining brownie batter to cover the marshmallows and along the sides of the Oreo cookies – spread it as evenly as possible.
  • 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).
  • 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 – 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.
  • 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!

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.

    Who Da Woman? Jenn Da Woman..these smoreo bars are s***, the cream of the crop, the diamond in the rough..holy cow is all I need to say..I think I pretty much covered everything wonderful about this recipe..

  2. 5 stars
    This was so easy to make. They are soo ooeey gooey and delicious. I used regular sized Oreos. Everybody loved them. Definitely going to make these again.

  3. Just made this last night and it’s so good! Not too sweet. I know some said there’s came out hard , but I wonder if they didn’t use parchment paper and used spray instead? I sprayed the edges of the pan, where the parchment didn’t reach and those pieces are a bit more on the hard side-still edible though. Super easy and a huge hit with the family! We be making again!

  4. Looks delicious. Even after reading the comments and rereading the directions, I am left confused.

    The step by step worded directions do not match the step by step photos of the recipe. My question is about the layering of ingredients and baking order.

    Is the order as follows:
    1. Graham crackers
    2. Brownie batter
    3. Marshmallow layer
    4. Second layer brownie batter
    5. Bake
    6. Second marshmallow layer
    7. Broil 1-2 minutes
    ??
    Thank you in advance for your help.

  5. I want to make this recipes for the coming weekend… I have a question…so do I just back the ingredients first minus the marshmellows? Or…put one layer of marshmellows let it bake for asking time take it out and then put another layer of marshmellows for 2 mins?

    1. HI Steph!- yes bake everything except the marshmallows and after everything else is baked, you add them on at the end for just a very short time (watch them carefully!)

  6. To eliminate the added sweetness from the cream filling in the Oreo’s, could I substitute with chocolate “wafers”? If so, I’d probably have to double up the wafers to equal the Oreo’s? I like sweets, I always want the key ingredient (chocolate, strawberry, lemon, banana, etc) to stand out.
