S’mores Bars
S’mores Bars are one of my mom’s signature desserts. While it’s not technically her original creation (I believe she found the recipe on the back of a box of Golden Graham’s® cereal), she’s made these for years and is practically famous for them. Everyone that enjoys S’mores goes crazy for these bars! They are the first thing to go at a party and she brings these to just about every function she attends. They are consistent crowd favorites.
Personally, they are one of my favorite treats! I’ve definitely eaten my fair share of these S’mores Bars over the years and can still confidently say I don’t think I’ll ever get sick of them.
The great news is, they couldn’t be easier to make. No more than 15 minutes of prep time, only six ingredients, and no baking required! These are definitely the easiest way to get your S’mores fix– and it doesn’t even matter what season it is, Fall, winter, spring, or summer– it’s always the right time for S’mores!
How to make S’mores Bars
- Microwave. Combine a portion of the marshmallows, a portion of the chocolate chips, butter, and corn syrup. Microwave until melted and smooth.
- Add remaining ingredients. Once the above mixture is melted and smooth, mix in the remaining ingredients until combined. It gets thick and sticky!
- Press into pan. Once everything is mixed, press it all into a pan. The bars need a bit of time to firm up and harden. And like anything wonderful, the waiting is definitely the hardest part of the whole process!
And (just being real here) only 60% of the S’mores Bars ever make it through the full “setting up time.” Just saying.
S’mores Bar tips
- Grease the pan. These treats are gooey and sticky! With a well-greased pan, these bars come out easily. Alternatively, you can line the pan with parchment paper or foil.
- Flavor enhancements. I add a little vanilla extract to the melted marshmallows, which amps up the flavor of these treats. If you don’t have it on hand, the bars will still be great without it!
- Use high-quality milk chocolate. You’ll get both a better melt and better flavor. My favorite for these bars is either Ghirardelli® or Guittard® (not sponsored). Cheaper brands can have a waxier content that is far less flavorful and doesn’t melt down as well.
- Find a cereal you love. While Golden Grahams cereal works great and is tasty, I’m partial to the off-brand (Malt O Meal®) Honey Graham Toasters (not sponsored).
- When microwaving the marshmallow mixture, microwave in short bursts and make sure to stir often between bursts. The ingredients are still melting even outside of the microwave!
- Don’t over-compress. Once you’ve spread the sticky-coated cereal mixture into the pan, avoid compressing it too much. Over-compressing the bars will yield hard bars that are tougher to eat.
Quick Tip
Use fresh, soft marshmallows. The fresher and softer the marshmallows, the chewier the S’mores Bars will be. When you’re at the store, press on the bags of marshmallows and pick the softest one.
Storage
These S’mores Bars are best the same day they are made. After that, they quickly get harder and become stale.
Because of the individual marshmallows throughout the bars, these don’t freeze or thaw particularly well (the marshmallows harden as they thaw).

S'mores Bars
Equipment
- Baking pan 9 x 13-inch
Ingredients
- 8 cups graham cracker cereal such as Golden Grahams, see note 1
- 6 cups miniature marshmallows divided
- 2 cups milk chocolate chips divided, see note 2
- 5 tablespoons unsalted butter cut into cubes
- 1/4 cup light corn syrup
- 1 teaspoon vanilla extract
- Cooking spray
Instructions
- Generously grease a 9x13-inch pan and set aside. Place the cereal in a very large bowl and set aside.
- In another very large, microwave-safe bowl, add 5 cups mini marshmallows, 1 and 1/2 cups chocolate chips, cubed butter, and corn syrup. Stir and place in the microwave for 2–4 minutes, removing to stir every 20 seconds for about 15–20 seconds, making sure to really scrape the bottom, then return to the microwave. Microwave until the mixture is just melted and smooth; don’t heat more than needed.
- Once mixture is smooth, stir in vanilla. Pour the mixture over the cereal and gently but quickly toss to combine. Add remaining 1 cup marshmallows and 1/2 cup chocolate chips and stir until just incorporated.
- Pour into the prepared pan. Spray your hands with cooking spray and gently press down the bars. (Don’t press them too hard or it will make the bars hard.)
- Let stand, uncovered, for 1 hour (refrigerate for firmer bars).

We had to use marshmallows without gelatin and not sure if that makes a difference but this did not work at all ☹️
Yeah I don’t see that being a great substitute here; the gelatin is needed to hold things together
I don’t often but milk chocolate, do you think ghirardelli semisweet would work? I’m trying to imagine it, and having trouble! I don’t want to go to the store!
They will be less sweet, but I think still delicious 🙂
Hello!
I loved your recipe so much that I included it in my S’mores recipe round-up. 🙂 Your pictures are great, too!
Love your site! – Laura
Thank you so much Laura! 🙂 That means a lot to me!
Hey there! Do you think you can make these without corn syrup, like rice krispie? Have you ever tried? They look delish!
Thank you! I haven’t tried them without corn syrup, but I’m sure they’d be okay without it and maybe some extra marshmallows!
