Table of Contents
The batter for these easy 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. It takes me longer to roast one perfect marshmallow over a campfire than it does to make this s’mores recipe!
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 summer dessert menu — including Memorial Day, Father’s Day, 4th of July, or Labor Day — 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 are definitely a hit here!
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.

Ingredients in Loaded S’mores Bars
To make the bars, 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 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
Note: Scroll down to the recipe card section of the post for the ingredients with amounts included and for more complete directions.
How to Make S’mores Bars
These very gooey s’mores bars are a cinch to make! Follow these basic instructions:
- 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 baking dish. Bake the bars until they have firmed up in the center and the edges have set.
- Don’t forget to cool them well before serving them!
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.
A Note on the Consistency of These Bars
These bars really ARE gooey as their name suggests! Over the past decade, I have had readers complain their bars don’t set up. To be honest, I don’t know why since I wasn’t in their kitchen.
As I always tell people, make sure you read the recipe twice before beginning, measure carefully, and bake correctly. However, I’ve had hundreds and hundreds more who have had great success and they leave glowing comments!
But, if you’re not ready for really gooey on the verge of potentially falling apart type of bars that are messy – but oh-so-good – then this may not be the dessert for you.
Baking FAQs
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).
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.
I used small marshmallows in this recipe, but you can also chop large marshmallows if that’s all you have on hand. Mini marshmallows are also fine but you won’t get as much gooey factor with those.
Storage Instructions
At room temperature: Leftover bars should be stored in an airtight container. They’ll last up to 1 week.
In the freezer: Let the bars cool completely before storing in an airtight container or freezer bag. They’ll last up to 6 months.

Soft and Gooey Loaded Smores Bars
Ingredients
- ½ cup unsalted butter, 1 stick, melted
- 1 large egg
- 1 cup light brown sugar, packed
- 1 tablespoon vanilla extract
- ¾ cup all-purpose flour
- 5 full-size graham crackers, roughly chopped (about 2 cups)
- 1 heaping cup mini marshmallows
- 1 cup semi-sweet chocolate chips
Instructions
- Preheat oven to 350F. Line an 8-by-8-inch baking pan with aluminum foil, spray with cooking spray; set aside.
- In a large, microwave-safe bowl melt the butter, about 1 minute on high power.
- Wait momentarily before adding the egg so you don’t scramble it. Add the egg, brown sugar, vanilla, and whisk until smooth.
- Add the flour and stir until just combined, don’t overmix.
- Add the graham crackers and any crumbs on cutting board, marshmallows, chocolate chips and fold to incorporate.
- Turn batter out into prepared pan, smoothing the top lightly with a spatula.
- Bake for about 20 to 22 minutes, or until bars have firmed up in the center and edges will be set. Some marshmallows may have developed a hint of golden color.
- Allow bars to cool in pan for at least 30 minutes before slicing and serving.

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!

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!
Hi Joyce! I had the same issue the first time I made them. But I love the flavor so much that I persevered. I now know when I make them, I have to let them set up in the pan for at least 10 hours! I know that seems ridiculous but it was so worth it!
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! :)
