What makes this Gooey Fudgy Marshmallow Brownies truly stand out?
What makes these brownies a total standout? It’s the perfect mashup of textures. You’ve got the rich, fudgy brownie as your base—chocolatey and decadent. Then, the marshmallow layer? It’s soft, sweet, and melts right into every bite. And that homemade chocolate frosting on top? It ties it all together with a glossy, show-stopping finish. Plus, here’s the kicker: they’re super easy to make. We’re talking pantry staples—brownie mix, marshmallows, chocolate chips. And in just 35 minutes, you’ve got a dessert that looks impressive but is secretly the easiest thing ever.
What You Need To Make This Gooey Fudgy Marshmallow Brownies Recipe?
Brownie Mix: You can’t go wrong with a boxed brownie mix, right? I love using Betty Crocker’s Fudge Brownie mix for that rich, chocolatey base. It’s super reliable and quick, but if you have a favorite brand or homemade recipe, feel free to swap it in! Just make sure it’s fudgy, not cakey—we want that gooeyness!
Marshmallows: The marshmallows are the real game-changer here. As soon as they puff up in the oven, they melt into this sticky, sweet layer that’s just perfect. You can use mini marshmallows for an even melt, but regular ones work just as well. Just don’t skimp on these—they add all the gooey magic.
Half and Half: This adds a bit of creaminess to the frosting, making it super smooth and rich. You could substitute with whole milk if that’s what you have on hand, but half and half give it that extra luscious texture.
Butter: Let’s be real—everything’s better with butter. It gives the frosting that creamy, melt-in-your-mouth quality. Just make sure to stir it constantly when you’re melting it, so it doesn’t burn!
White Sugar: This is for the frosting, giving it just the right amount of sweetness to balance the marshmallows and brownies. It’s a simple ingredient but makes a huge difference in that homemade taste.
Chocolate Chips: These little guys melt into the frosting and make it all come together. I usually go for semi-sweet, but if you like your chocolate more intense, go for dark. Either way, they add that glossy, rich chocolate finish that just makes everything better.
Steps To Make Gooey Fudgy Marshmallow Brownies:
Step 1: First things first—preheat your oven and whip up that brownie mix following the package directions. Easy, right? Just get those brownies baked until they’re perfectly fudgy. As soon as you pull them out of the oven, we’re going to move fast.
Step 2: While the brownies are still hot, grab your marshmallows and sprinkle them right over the top. Pop the whole thing back in the oven, but turn it off—yep, just use the residual heat to let the marshmallows puff up for about 2-3 minutes. They’ll get all gooey and melty. Trust me, that’s the magic moment. Keep an eye on them though, you don’t want them to brown—just puff.
Step 3: While those brownies are cooling a bit, let’s make the frosting. Grab a medium-sized saucepan and toss in the half-and-half, butter, and sugar. Now, here’s the key: bring it all to a boil, but keep stirring! Don’t let it stick to the bottom—burnt frosting isn’t anyone’s friend. Let it boil for just a minute, no more, and then turn off the heat.
Step 4: Now, here’s the fun part—stir in your chocolate chips until they melt and everything gets all smooth and glossy. Pour that chocolate goodness right over the marshmallow-topped brownies and spread it out evenly. Let it set, but honestly, waiting is the hardest part because you’re going to want to dig in immediately.
Step 5: Once it’s all cooled down a bit, slice them up into bars, and boom! You’ve got yourself some gooey, fudgy, marshmallowy heaven. Enjoy!
Tip:
Okay, here’s the mystery to getting these brownies to the next tier of extravagance: let them chill for about an hour after you pour on that glossy chocolate frosting. I know, I know—it’s so hard to linger. But trust me, once everything sets, the layers fuse together flawlessly. That first nibble will deliver you a fudgy brownie, gooey marshmallow, and rich chocolate frosting in one tasty mouthful. And hey, if you’re feeling grandiloquent, scatter a little sea salt on top while the frosting is still soft—it adds a killer salty-sweet vibe.
Frequently Asked Questions:
Can I make these brownies ahead of time?
Absolutely! You can totally make them the day before. Just keep them covered in an airtight container, and they’ll stay fresh and gooey for a couple of days. Just remember to keep them at room temp unless you want the frosting to harden in the fridge.
What if I don’t have half-and-half?
No worries at all! You can substitute it with equal parts milk and heavy cream. If you don’t have heavy cream, you can just use milk. It’ll still give you that creamy texture for the frosting—promise!
Can I add other toppings or mix-ins?
Oh, absolutely! If you’re feeling adventurous, you can throw in some crushed nuts, and toffee bits, or even drizzle some caramel on top of the chocolate frosting. Get creative with it—it’s your brownie masterpiece!

- 2 cups of marshmallows
- 6 tablespoons of half-and-half
- 6 tablespoons of butter
- 1 1/2 cups of granulated white sugar
- 1/2 cup of semi-sweet chocolate chips
Instructions
- Prepare the brownie mix just like the package tells you to. Once those brownies come out of the oven, while they’re still nice and hot, spread the marshmallows evenly over the top. Now, pop the brownies back into the oven (that’s already turned off, by the way) and let the marshmallows puff up for about 2-3 minutes. Keep an eye on them so they don’t exaggerate it!
- While the marshmallows are doing their thing, grab a medium saucepan and combine the half-and-half, butter, and sugar. Bring it to a boil, but keep stirring to make sure nothing sticks or burns at the bottom. After about a minute, toss in the chocolate chips. Keep stirring until they’ve completely melted into a smooth, rich frosting. As soon as it’s ready, spread that delicious chocolate frosting all over the marshmallow-topped brownies.
