S’mOreo Seven Layer Bars

These are every bit as AMAZING as you're imagining they are! Oreos, marshmallows, Hershey bars, chocolate chips, and white chocolate chips. Yum!! Ooey gooey goodness! #oreo #magic #cookie #bars

I am constantly composing posts in my head. All. day. long.

Every situation I’m in through the day becomes a blog post. And I always think, “Oooooh, yeah, that’s a good one. I need to remember that!”

And yet, somehow, every evening I sit down to write my post and draw a big, fat, mental blank. Fortunately, you guys are awesome and never complain :)

These are every bit as AMAZING as you're imagining they are! Oreos, marshmallows, Hershey bars, chocolate chips, and white chocolate chips. Yum!! Ooey gooey goodness! #oreo #magic #cookie #bars


Ah, but that does remind me (not that I’m calling this person a complainer)… I received a comment about the last batch of 7-layer bars that I posted. She said that she had made the recipe twice, but the marshmallows burned both times. Which was perplexing since mine had turned out perfectly golden and gooey.

But her comment was logical– the bars are in the oven for an hour (or more), shouldn’t my marshmallows have burnt to a crisp? And why didn’t they? And how can I make sure there are no other mallow casualties in the making of seven-layer bars?

Obviously, I had to re-make the bars to answer these questions.

Since I loved the way the Gingerbread Oreo 7-Layer Bars turned out, I decided to create a similar bars recipe but without the seasonal flavors. A traditional S’mOreo is 4 layers: one Oreo half, a toasted marshmallow, a chocolate bar, and a second Oreo half. We’re adding three more layers here: semi-sweet chocolate, white chocolate, and sweetened condensed milk.

I have to say… these bars are everything you’re imagining them to be. And probably more. Oreo goodness, ooey gooey toasted marshmallows, and sweetened condensed milk bringing everything magically together.

Plus, I’ve solved the marshmallow-burning mystery. I suspect the marshmallows would be fine as long as they were somewhere beneath the sweetened condensed milk and not the very top layer. However, I didn’t want to run the risk of burning them, so I made sure that they were the first layer of goodies right on top of the crust. Then I piled the chocolate chips, Oreos, and SCM on top so that the marshmallows were covered really well. And voila! No burning at all.

I so enjoy a good marshmallow mystery ;) .

S’mOreo Seven Layer Bars


  • 15 Oreos (1 1/2 cups), crushed
  • 3 Tbsp. butter
  • 1 cup miniature marshmallows
  • 1 cup Hershey Milk Chocolate bars, broken into pieces
  • 1/4 cup semi sweet chocolate chips
  • 1/4 white chocolate chips
  • 5 Oreos, crumbled
  • 14.5 oz can sweetened condensed milk


  1. Preheat the oven to 350 degrees. Prepare an 8x8 baking dish by lining it with parchment paper and spraying lightly with a nonstick cooking spray.
  2. Place the Oreos in a zip top bag. Seal the bag and use a rolling pin to crush them. Open the bag and add the butter. Place in the microwave, standing up. Heat for 30 seconds. Seal the bag again, and smush until the butter is fully incorporated with the cookie crumbs.
  3. Press the crumbs well into the bottom of the dish. Bake the crust for 10 minutes.
  4. Remove crust from the oven and top with marshmallows, Hershey bars, chocolate chips, white chocolate chips, and crumbled Oreos. Pour the sweetened condensed milk evenly over the top.
  5. Bake for 60 minutes until the top is golden and edges are bubbly. It should feel somewhat set when you push it, even though it will be melted and gooey.
  6. Let cool completely before cutting and serving.

  1. Oh holy heck. These are AMAZING. But I was just wondering how marshmallows would fare in magic bars. Now I know the trick. More bars…coming next week. LOL

  2. You and I are totally on the same wavelength this week :-) I made lemon magic bars on Sunday with marshmallows as one of the layers…no burning here either and mine were even on the top with just the milk covering them. Hooray for these bars being the finish of a marshmallow mystery…they are insanely delicious looking!!!! I want to lick my computer screen for a taste!!!

  3. Seriously I just posted Oreo Smore’s bars!! When I was eating them I thought to myself hmm sweetened condensed milk next time! Wow these look spectacular everything I love and more. The worst part of the recipe is waiting for the bars to cool completely, I am so impatient when it comes to sweets!

  4. i freaking love layered bars right now! and I can’t get enough inspiration to make more varieties. ashton, these are over the top in the best way possible. a must make, for sure. and your photos are stunning. love the food styling in photo #2!

  5. These look so yummy! I really like the combination of the Oreos and Smores flavors. I have never made magic bars, I think I need to go make some soon!

  11. I would eat the entire pan! YUM!

  12. Oreos in any form are my weakness. These look amazing.

  22. These look CRAZY! Now that is a serious bar. And your shots are gorgeous! Way to get me craving an Oreo… :)

  23. These look delicious! I wonder what would happen if I added graham Cracker somewhere…

    • I almost did! But then I decided that I wanted to stay consistent with the idea of an actual “s’moreo” where the Oreo = the graham cracker. But I’m sure it would be great! Maybe use the graham cracker crumbs as the crust and just crumble the oreos over top!

    • I was thinking the same thing – add graham crackers somewhere. I was thinking crumbled grahams with the crumbled Oreo layer, keeping the Oreo crust. Yum.

  30. Is the cooking time really 60 minutes? Mine were way overcooked. Has anyone else made these?

    • Hm… it was 60 minutes for me. I started checking them at 45, but didn’t feel like they were set enough until about an hour.

  31. Amaaaaaazzzing! That’s all.

  32. I agree with the above comment….I cooked for 60 minutes and mine were extremely overcooked. I have a pan of burnt mess :(.

  33. These looked awesome and I was making them for Super Bowl tomorrow. But they came out burnt after 30 minutes.
    60 minutes is definitely too long for 500 degrees!!

  34. Talk about chocolate overload! These sound absolutely amazing. I am going to try them ASAP!
