Soft and Gooey Loaded S’mores Bars — No campfire required for these soft, gooey, rich s’mores bars that are loaded with texture and flavor! The combination of chocolate, graham crackers, and marshmallows, all suspended in a buttery, brown-sugar based dough, is just magical.
Easiest S’mores Dessert
Who can resist super soft, chewy, gooey bars that are loaded with great texture? The batter for these s’mores bars is a stir-together, one bowl recipe that comes together in less than 5 minutes before turning it out into a pan and baking.
I used my easy, go-to blondie recipe that has served me so well over the years, and I adapted it yet again. I love the batter because it’s buttery and made with brown sugar, and it takes on caramel notes while baking.
To it, I added the classic s’mores ingredients: chopped graham crackers, marshmallows, and chocolate chips.
When adding the smores components to the batter, it’ll appear that there are more add-ins than batter. And that’s fairly accurate.
The abundance of add-ins ensures the bars are taste like taking a big bite of warm, gooey s’mores rather than eating a blondie that has a few marshmallows or chocolate chips added.
The graham crackers retain a bit of crunch while they bake and melted chocolate chips go so well with graham crackers.
The marshmallows are very slightly toasted and they puff, enveloping the bars in their sticky wonderfulness. Those strings of marshmallow goo are heaven on earth.
It takes me longer to roast one perfect marshmallow over a campfire than it does to make this s’mores recipes.
I have no patience for slow-cooked, perfectly golden marshmallows. I usually employ the ignite-and-blow-out strategy for my roasted marshmallows. A little black never hurt anyone, but no worries about finding a campfire to make these.
They’re some of my favorite gooey bars. There’s a great balance of rich and satisfying density from the blondie dough, coupled with lightness and fluffiness of the marshmallows.
The combination of chocolate, graham crackers, and marshmallows, all suspended in a buttery, brown-sugar based dough, is pure bliss.
If you don’t have anything on your Labor Day dessert menu plan, or have no plans to stand around a campfire any decade soon, may I suggest these?
They’re ready from start to finish in under 30 minutes, and will be a hit with friends and family. They were definitely a hit here!
What’s in the S’mores Bars?
To make this easy s’mores dessert, you’ll need:
- Unsalted butter
- Egg
- Light brown sugar
- Vanilla extract
- All-purpose flour
- Graham crackers
- Mini marshmallows
- Semi-sweet chocolate chips
How to Make S’mores Bars
First, you’ll need to melt the butter in a microwave-safe bowl. Let it cool for a minute or two before adding in the egg, brown sugar, and vanilla.
Stir the flour into the butter mixture and whisk until just combined. Then, add the mix-ins.
Turn the batter into a greased and lined 8×8-inch pan. Bake the bars until they have firmed up in the center and the edges have set.
Can I Double This Recipe?
Yes, you may double the recipe and bake the bars in a 9×13-inch pan. However, readers have said that doubling the recipe results in less ooey gooey bars (I’m assuming because they require extra time in the oven).
How to Store the Bars
S’mores bars will keep airtight at room temperature for up to 1 week, or in the freezer for up to 6 months.
Tips for Making This S’mores Dessert
I prefer using semi-sweet chocolate chips to offset some of the sweetness from the dough and marshmallows. However, you’re welcome to chop up a Hershey’s chocolate bar and throw that in instead.
These bars remain fairly gooey in the center even after being baked. If you want firmer bars, leave them in the oven for longer.
I used mini marshmallows in this recipe, but you can also chop up regular-sized marshmallows if that’s all you have on hand.

I did these with half the sugar, salted butter, and some salt in the dough. They were great! I’m going to do a graham cracker crust under them next time as well for added crunch and buttery goodness, as well as helping them hold their shape.
Glad that they turned out great and a graham cracker crust sounds like a great addition, too!
I am on a blonde kick! Making these for the 2nd time in a week, husband requested them again! The first disappeared in 2 days. We love extra gooey things so I baked like suggested then when they were done, added more marshmallows, chopped graham crackers and extra chocolate chips on the top and baked long enough for the marshmallows on top to brown! They were amazing and still gooey in the middle!! Great recipe!
Thanks for the 5 star review and I am glad that these have been on repeat this weekend and that you love extra gooey things! Me too :)
Just made these. They came out good with no trouble cutting them after about 3 hours cooling. I really don’t like super sweet treats so I only used 1 cup mini marshmallows, not a heaping cup, I didn’t pack the brown sugar heavily, and I used Guittard Dark Chocolate Chips. I also used salted butter. They are not too sweet with these changes. I think I may have slightly over-baked them as I was worried about them setting up. I baked them for 23 minutes. The problem is that the marshmallows just kind of disappeared as chewy, golden bits in them. You can’t really see them. Maybe I should have used more. They are not gooey looking. They are very moist though with the dark chocolate chips, with a bittersweet taste which I love. They taste great! I did sprinkle more marshmallows on top and hit them with my kitchen torch till they browned. It looks great and gave them some more of a marshmallow look and taste.
Thanks for trying the recipe and yes if you had followed the recipe and used the intended measurements for the marshmallows I am sure the bars would have turned out more gooey but next time you can try that perhaps!
I made the s’more bars for Memorial Day, the 4 th of July and a few times in between. My husband is so excited when I make them and so happy when I put them in his lunchbox. He does share and his coworkers love them too. They are so easy to make. Thanks for a wonderful recipe.
Thanks for the 5 star review and glad these are a hit with your husband and his coworkers, too!
These bars are the BOMB!! I took some to school for the staff room and they were gone in an hour! I dropped some off for my son’s family another time and he said these were the the BEST bars that I ever made. I followed the recipe exactly and there is no need for any changes. Thank you for sharing!
Thanks for the 5 star review and I am so glad that these were a hit at the school and with your family, too!
These were a smash with my family and they devoured them! Thanks for sharing :)
Thanks for the 5 star review and glad they were a smash hit and devoured!
Doubled recipe — divided between a 9×13 and an 8” loaf pan (wanted some to take to work and some for home). Cooked for about 25 minutes. They were excellent!! I had extra marshmallows I wanted to use up — so melted it with a tablespoon of butter in the mosrowave and added that to the batter. Chewy and delicious! A hit!!
Thanks for the five star review and I’m glad that your doubled recipe was delish and a hit!
Deliciously gooey, crispy, and so easy to make! Going to add pretzels next time! Made these for a party and they disappeared fast! :) Good thing I made a double recipe and had some waiting when I got home! :)
Thanks for the 5 star review and glad these were delish and disappeared fast!
YUM!!! Making them today for the 2nd time!
Thanks for the 5 star review and I am glad you’re making them for a second time!
I’m so sorry, but these were awful. My son wanted smores bars so bad. They looked good so I gave it a shot but they are nothing more than melted sugar with more sugar and some butter. The marshmallows disintegrated into a sticky mess. All you taste is melted sugar. They don’t taste like smores. Definitely taste like a blondie recipe that has been revisited.
I’m sorry they didn’t work out for you. If you do want to give any other smores bars recipes a try these https://www.averiecooks.com/smores-bars/ or these https://www.averiecooks.com/chocolate-chip-cookie-smores-bars/ are more current than this recipe (posted in 2013) and may work better for you. Thanks for trying.
I’ve made these several times now and my family devours them! Myself included:) I’ve started baking it in a 9×13 instead of 8×8 because it gets crispier and the brown sugar/butter combo almost turns into caramel. It’s heaven! If you prefer soft bars though then stick with 8×8. Either way it’s amazing!
Thanks for the 5 star review and thanks for sharing your tip about baking in a 9×13 pan for crispier bars and the brown sugar/butter turning into an almost-caramel!
What a delicious and rich treat! And a great way to enjoy s’mores without the hassle. My only changes were adding a bit of salt to offset the extreme sweetness, and I used milk chocolate chips instead of semisweet, because who puts semisweet chocolate on s’mores?
Glad these were a rich and delicious treat for you!
I do like semi sweet chocolate on smores because it’s less sweet than milk chocolate and they are already sweet enough from the marshmallows (which is why I don’t then need to add salt to counter the extra sweetness from milk chocolate).
That makes sense. Maybe I’ll try that next time, though in general I prefer salty and sweet over bitter and sweet.
Tried these bars this weekend and they were delicious! Next time, I would make a couple of adjustments:1 pack of graham crackers instead of 1/2 a packLittle more flour, maybe something closer to 7/8 cup3/4 cup semi sweet chocolate chips separated, with 1/2 cup mixed in and 1/4 cup sprinkled on top after putting dough into baking panI also added salt to the dough to counteract some of the sweetness and used regular marshmallows cut into 1/4s and sprinkled on top. Maybe I’d add some crumbled graham cracker on top after baking too!Thanks for a great recipe!
Glad you enjoyed the bars!
