Marshmallow Creme Crunch Brownies

My recipe for marshmallow creme crunch brownies came from my kids’ former stepmom. She brought these treats to a holiday gathering and I asked her to share the recipe. Luckily she did because they have become a favorite in our family and a food day favorite at work. (Which helps me defend my title as Best Food Day Chef within the Personnel department.)

Update: Five years later I made these even better by using Golden Grahams cereal in place of the crispy rice cereal. Get the recipe for marshmallow creme graham brownies.

Do you bake a similar version of this recipe? I’ve also seen it with marshmallows instead of the marshmallow creme, like these from Brown Eyed Baker.

Sweet wishes,

There's so much to love about these brownies, from the fudgy brownie bottom to the marshmallow creme center and the crunchy chocolate and peanut butter topping. They are one of my top 10 favorites.

    1. Hi Pam. You should be fine to omit the peanut butter altogether. You’ll simply stir the cereal into the melted chocolate and press it gently into the marshmallow creme. Sweet baking! Staci

  1. It’s my husbands birthday and I was trying to think of something sweet to take to our ballgame tonight. I think these will be perfect! I am going to try and fourth this recipe though as we go back on our Paleo eating ways tomorrow and don’t want to waste a 9×13 pan of goodness! Thanks for sharing!

  2. Hi Staci – Hope you see this comment…Do you think I can just forgo the peanut butter? I have a real taste aversion issue with Chocholate and Peanut Butter (I know, the horror!). I’m not sure if you need the binding quality of the PB in that top layer. Thank you!

    1. Hi Lisa – it should be fine to leave out the peanut butter in the topping. The melted chocolate will bind with the cereal. Just be sure to get it spread on the marshmallow creme right away so that it all sticks together once it cools and you cut them into bars. I’d love it if you come back and let me know how it turns out for you. Staci

      1. Finally made these…they’re positively sinful! I used 16oz choc chips since I omitted the PB, and melted them in a double boiler. Fabulous!!

        1. Oh that’s great to hear, Lisa! They take a while to make so I don’t get to make them as often as I’d like. That’s probably a good thing. 🙂 Thank you for taking time to come back and share. Sweet wishes – Staci

  3. What’s Taking place i am new to this, I stumbled upon this I have discovered It absolutely useful and it has helped me out loads. I hope to give a contribution & help different users like its helped me. Great job.
