I love pot luck and picnic food, especially the desserts!

These brownie bars are loaded with peanuts, mini marshmallows, caramel sauce, AND chocolate frosting!

Good thing this recipe makes enough to share with a crowd!

Loaded Marshmallow Brownies

These loaded marshmallows are the rich and gooey dessert your heart has been dreaming of. Made with a homemade brownie base and given chocolate frosting and caramel sauce over the top you can’t help but fall in love at first bite. The marshmallows are toasted on the outside, but keep their middles perfectly gooey and soft, which tastes superb with the nuts! Smooth caramel is hidden underneath all those crunchy, dry roasted nuts and then sinfully sweet chocolate frosting is drizzled over the entire pan!

What are loaded marshmallow brownies?

They are a fantastic and wonderful twist and upgrade to the classic regular chocolate brownies. Packed with so much added flavor and love in every square this is a dessert you share with the world (or at least your next party). Made with a rich and flavorful brownie and then topped with chocolate frosting, marshmallows, caramel sauce, and more these are not your average brownies.

Serve these brownies up at your next party and watch them disappear they’re always a crowd favorite and with so many toppings loaded onto every square, there’s a little bit on something for everyone.

Recipe Tips

If desired you can cook your brownies in a large baking dish instead of a sheet pan. Use a 9×13 baking dish instead of a sheet pan to get fewer servings, but thicker brownies. Please note that the baking time will be different as a result. Make sure that the brownies are mostly cooked all of the way through before adding the marshmallows on top.

To melt your chocolate you will need to do it in 30-second intervals in the microwave and stir well between each. it shouldn’t take longer than 2 minutes and if you overcook the chocolate it will become a hard clumpy mess as it seizes. Alternatively, you can melt in it a small pot on the stove over very low heat, stirring almost constantly.

FAQs

How long are loaded brownie bars good for?

These brownies can be kept stored in an airtight container at room temperature for up to a week. For the best taste experience, I recommend eating them within 3-4 days so that they don’t dry out.

What can I use besides peanuts?

If you don’t want to use peanuts in this recipe you can simply omit them. That said alternative nuts that would also taste great would be chopped walnuts or pecans.

Can I use my own caramel?

In my Salted Caramel Thumbprint Cookies recipe, I have an easy DIY caramel sauce recipe that would be perfect for these brownies if desired. If you want to leave the caramel sauce as salted it would pair wonderfully but even omitting the salt will still give you a great tasting sauce for these brownies.

    I love s’mores, but I like your version, too! I agree completely that marshmallows need that char. If they don’t, they’re just kinda there for me. These look really amazing!

    I never was much of a s’mores fan, Tanya. I thought them to be a whole lotta hoopla over nuttin. Just give me the chocolate and I was happy. This treat, though, with the brownie bottom, is more my style. While others are toasting marshmallows for their s’mores, I’ll enjoy a few of these, thank you very much. 🙂

      Really no marshmallows for you? I actually hate eating them unless they are toasty and melty!

    I’m not a huge fan of s’mores either. I like the chocolate and toasted marshmallow but could do without graham crackers. So, your version is perfect for me!

    I like s’mores, but the messiness annoys me. These look like a less messy but equally delicious version!

    This is my kind of brownie!! Pinned!

    I also love a charred marshmallow. People never understood why I always to set marshmallows on fire when we camped. 🙂 Good to know I’m not alone.

    OMG we are identical!! I LOVE me a blackened, toasty marshmallow. Then I eat off the top and blacken it again. And no, the chocolate is never the right meltiness. I much prefer s’mores as bars, pie, and brownies! Like these!

      I used a jelly roll pan for this recipe, so the brownies are on the thin side. You could use a 9 x 13 pan but your brownies be thicker so you may want to cut them into smaller pieces.

        In your instructions you never say what you do with the flour (from your ingredients list) is that mixed in with cocoa, eggs, vanilla etc? I just printed this out because it truly looks delicious!
