The Treat That Made My Mom Famous (Well, Kinda)
S’mores Cereal Bars are one of my mom’s signature desserts. She didn’t come up with the recipe (pretty sure it’s from the back of a cereal box), but she’s made them for years and is basically “famous” for them with family and friends.
If you love s’mores, you’ll be hooked—graham cereal, gooey marshmallows, and melty chocolate. They always disappear first at any party.
They’ve been one of my favorite treats for as long as I can remember, and even after way too many over the years, I still don’t think I’ll ever get tired of them!
S’mores Cereal Bars Ingredients
- Graham cereal: Use any kind you like—Golden Grahams® or a store-brand version.
- Marshmallows: Softer marshmallows make chewier bars—pick the squishiest bag.
- Chocolate chips: Pick a good brand so the chocolate melts nicely and tastes rich.
- Butter + corn syrup: These help everything stick and keep the bars soft.
- Vanilla: Adds a subtle sweetness and depth to the bars.
How To Make S’mores Cereal Bars (Tips)
- Grease the pan: Spray well or use parchment so the bars don’t stick.
- Microwave slowly: Heat in short bursts, stirring well each time.
- Don’t press too hard: Gently press the mixture into the pan so bars stay soft.
- Use a big bowl: Mixing is easier (and less messy) in a very large bowl.
Storage
S’mores Cereal Bars are best the day they’re made—after that, they start to harden and lose texture. They don’t freeze well since the marshmallows get hard after thawing.

Equipment
Ingredients
- 8 cups Golden Grahams cereal 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
- 1/8 teaspoon salt
- 1 teaspoon vanilla extract
- Cooking spray
Instructions
- Spray a 9×13-inch pan well and set aside. Add cereal to a large bowl.
- In a separate large microwave-safe bowl, add 5 cups marshmallows, 1-1/2 cups chocolate chips, butter, corn syrup, and salt. Microwave in 20-second bursts, stirring well each time (scraping the bottom), until melted and smooth—about 2 to 4 minutes total. Don’t overheat.
- Stir in vanilla, then quickly pour the mixture over the cereal. Toss until evenly coated. Take your time here—make sure every piece is well coated. Stir gently to not crush the cereal.
- Stir in the remaining 1 cup marshmallows and ½ cup chocolate chips. Pour into the prepared pan.
- Lightly spray your hands with cooking spray and gently press the mixture into the pan. Don’t press too hard or the bars will be too firm.
- Let sit uncovered at room temp for 1 hour, or refrigerate for firmer bars.

Hello, these sound SO good, but I never buy corn syrup. Is there something else I can use for a substitute?
I haven’t tested it with anything else so I can’t say for sure! So sorry!
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!
