Roasted Marshmallow Brownies
🔥 Roasted Marshmallow Brownies — The Campfire Treat You Can Make in Your Oven
If gooey, chocolatey, marshmallow‑topped brownies don’t make you smile… I’m not sure we can be friends.

When Brownies Met S’mores and Fell in Love
You know those desserts that make you feel like a kid again? The ones that transport you straight back to summer nights, sticky fingers, and the smell of toasted marshmallows in the air?
That’s exactly what these Roasted Marshmallow Brownies do — except you don’t need a campfire, a tent, or to swat away mosquitoes while you eat them.
It all started on a rainy Saturday when my kids were begging for s’mores, but the weather was saying, “Nice try.” I decided to bring the campfire indoors — minus the smoke — and the result was pure magic: a rich, fudgy brownie base swirled with Nutella, topped with a cloud of mini marshmallows roasted to golden perfection.
They’re indulgent. They’re nostalgic. And they’re dangerously easy to make.
This baby has been craving things I don’t normally want, like brownies. And I really like tomatoes right now, but they both give me heartburn so I can’t/shouldn’t really eat them. Nothing too extreme and it’s not one thing all the time, but it’s kind of crazy some of the things I really want to eat.
My poor kids are just stuck trying things I want to eat. They have been a little stubborn about eating lately, it’ll be crazy in six weeks when I’m home and I want to eat normal things again!

💡 Baking Tips for Brownie Bliss
- Don’t Overbake – The key to fudgy brownies is pulling them out when the center is just set.
- Nutella Swirl – For a pretty marbled effect, reserve a few spoonfuls of Nutella and swirl it into the top before baking.
- Marshmallow Watch – Broiling marshmallows is a blink‑and‑you‑miss‑it situation. Stay close!
- Clean Cuts – Use a sharp knife and wipe it clean between slices for perfect squares.
- Line Your Pan – Parchment paper makes lifting the brownies out a breeze.
🎨 Recipe Variations to Try
- Peanut Butter Dream – Swap Nutella for peanut butter and top with chopped Reese’s cups.
- Mocha Magic – Add 1 tablespoon espresso powder to the batter for a coffee‑chocolate kick.
- Salted Caramel Swirl – Drizzle caramel sauce over the marshmallows before broiling.
- Rocky Road Remix – Add chopped nuts and extra chocolate chunks to the batter.
- Holiday Twist – Sprinkle crushed candy canes over the marshmallows for a festive touch.

🏆 Final Thoughts
If you’ve been looking for a dessert that’s equal parts gooey, chocolatey, and fun, this is it. These Roasted Marshmallow Brownies are the kind of treat that makes people linger in the kitchen, fork in hand, “just evening out the edges.”
So here’s my challenge to you: carve out a little pocket of time this week — maybe on a rainy afternoon, maybe on a lazy Sunday — and make these Roasted Marshmallow Brownies. Don’t overthink it. Don’t wait for a “special occasion.” Just pull out the butter, cocoa, and marshmallows, and let the magic happen.
Because here’s the truth: dessert isn’t just about sugar and flour. It’s about the way your kitchen smells when the brownies are baking. It’s about the way the marshmallows puff up and turn golden under the broiler, and how everyone suddenly appears in the kitchen “just to check” on them. It’s about the first bite, when the crackly marshmallow top gives way to the fudgy, Nutella‑swirled center, and you can’t help but close your eyes for a second.
These brownies are more than a recipe — they’re a little piece of joy you can hold in your hands. They’re the kind of treat that makes kids giggle, makes grown‑ups sneak an extra square, and makes even the busiest day feel like it has a sweet ending.
And here’s the best part: they’re yours to make your own. Add your twist, swap an ingredient, pile on extra toppings. Then share them — with your family, your neighbors, your coworkers, or just with yourself and a good book.
So go ahead. Preheat that oven. Line your pan. And get ready to create something that will have people asking, “When are you making those again?”
Because life’s too short to wait for campfire season to enjoy roasted marshmallows — especially when you can have them layered over rich, chocolatey brownies any time you want.
