Tools used in this Marshmallow Crunch Brownie Bars recipe:
9×13 Baking Pan – The straight edges and even cooking of this pan are ideal for bars and brownies.
Stand Mixer – The classic stand mixer, it’s always a huge help to get things mixed a heck of a lot faster. Plus, that blue!
Hand Mixer – For smaller jobs you don’t want to pull the large mixture out for, this hand mixer is a breeze.
Dark Chocolate Chips – These are the best dark chocolate chips, I keep them on hand in volume! More and more stores carry the brand now too, so when yours has a sale buy several to keep on hand.
Unsweetened Cocoa Powder – This cocoa powder gives an amazing, dark, rich chocolate flavor. I also highly recommend the Trader Joe’s Brand of cocoa powder.

  1. I love these awesomeness marshmallow crunch brownie bars! This look so great, especially with that Nutella!

  2. I’ve been asked to make desserts for a wedding, but need to bake and have them ready a few days ahead of time- how do these store? do they have to be refrigerated?

  3. Did you melt the marshmallows? It looks like a cohesive and solid layer of marshmallow, not individual miniature ones.

  4. Oh my heavens…. I could gobble down one (or 3) of them right now…look so yummy.
    Thanks for your recipe Sabrina.

  5. Can Nutella be substituted for something else in the Marshmallow Crunch Brownie Bars? I don’t cate for the taste of Nutella. Thank you. 

  6. These look amazing. Though I’m not a huge fan of dark chocolate, I can tweak it to my taste. Seriously thinking of using Coco pebbles in place of Krispy rice. Hehe. But, how did you get the marshmallow so gooey? Did it just melt down a bit from the heat off the brownie and the topping?

  7. These marshmallow crunch brownie bars look unreal! Definitely i will try to cook them for my kids, coz it’s better than snickers and other chocolates. Thx for sharing recipe!

  8. Thanks for sharing this wonderful recipe with us. It looks yummy and amazing, i think i came accross this recipe at the right time. Now i have somthing special to prepare for my kids on our next picnic. Awesome post, kudos!!!

      1. You say to use 2 cups dark chocolate chips, but in your instructions, you say melt the milk chocolate chips?? I am confused, please let me know, as I would like to make this soon.

        1. Woops! Sorry for the confusion. I am a HUGE fan of dark chocolate so I use it in both the brownie base and in the topping. I updated the recipe directions for dark. That being said if you’re a fan of milk chocolate you can absolutely go with all milk chocolate here. The flavor won’t be as intense but hey different chocolate preferences for everyone 🙂

  9. These are awesome!! We make one similar to this and they’re always the first to go at parties! so good!

  10. Whoa, those look so good – and dangerous because I’d have a hard time stopping myself! 🙂

    1. I wouldn’t worry about that too much – if there’s other grabby hands in your house they’ll be gone before you can stuff yourself!

  11. Love the added crunchy layer of these brownies! (I’m all about sharing sweets. I always send extras to friends and neighbors!)

  12. So decadent and, I’m sure, delicious! No, I imagine you didn’t have any trouble sharing these goodies 🙂

    1. Out of all the treats I made that day, I think these might have been the most popular! My husband didn’t want to share these with anyone!

  13. I think I just fainted from seeing your pictures and reading this recipe! OMG!!! And I’m not even a huge brownie person. My hubby would go nuts over these! I would too 🙂

  14. This looks incredible!! Love that gooey layered brownie. Wish I were there when you baked them all 🙂
