If you love s’mores but don’t love building a fire (or cleaning up sticky hands after), these S’mores Cereal Bars are your year-round solution. They’ve got that classic combo—gooey marshmallow + chocolate + graham crunch—in a grab-and-go bar.
They’re also perfect when you need a dessert that feels fun but takes almost no effort: melt, stir, press, and let them set. That’s it. Total time is about 20 minutes, and there’s no oven required.
Bonus: these are made for sharing—class parties, potlucks, sleepovers, or an “indoor campfire” movie night.

S’mores Cereal Bars vs. Classic Campfire S’mores
What’s the difference?
Classic s’mores are built and toasted one at a time. These bars deliver the same flavor in one pan, and every bite has a little of everything.
When you’d choose the bars:
- You need a party-friendly treat that travels well
- You want “s’mores vibes” in any season
- You want less mess than individual s’mores (especially with kids)
How to Make S’mores Cereal Bars
** You can find the full recipe ingredients and instructions on the printable recipe card below.
These come together in one pot. You’ll melt the marshmallow base, stir in vanilla, then quickly coat the cereal and chocolate chips before pressing into a pan.
Method: Stovetop (Primary Method)
- Prep the pan: Lightly spray or butter a 13×9-inch pan; set aside.
- Melt: In a large saucepan [paid link] over low heat, melt butter and the bag of marshmallows, stirring until smooth. Remove from heat; stir in vanilla.
- Mix: Stir in the cereal and mini milk chocolate chips until evenly coated.
- Press: Press mixture firmly into the pan using a buttered spoon or lightly oiled hands.
- Set: Cool at least 1 hour (or until firm). Store covered at room temperature.
Optional Garnish (Chocolate Drizzle)
- Microwave mini chocolate chips with a little milk for ~20 seconds, stir until smooth (heat 10 seconds more only if needed).
- Drizzle with a fork or pipe from a snipped sandwich bag.
Tip: overheating can cause chocolate to seize—short bursts only.
What Can Go Wrong (& How to Fix It)
- Bars won’t hold together → Press harder into the pan while still warm; measure cereal carefully (too much cereal dries it out).
- Too hard once set → Next time, melt marshmallows gently (low heat) and don’t overcook the mixture.
- Too sticky to press → Lightly oil hands or butter the back of a spoon.
- Chocolate drizzle seized → Use very short microwave bursts and stir well; avoid overheating.
Ingredients (& What They Do)
** You can find the full recipe ingredients and instructions on the printable recipe card below.
- Mini marshmallows (10.5 oz / 5½ cups): the gooey binder and signature s’mores texture
- Butter (5 Tbsp): richness + helps everything melt smoothly
- Vanilla (1 tsp): boosts the “dessert” flavor
- Mini milk chocolate chips (1 cup): chocolate pockets throughout
- Malt-O-Meal S’Mores cereal (8 cups): crunchy graham/chocolate base
- Optional drizzle (¼ cup chips + 1 tsp milk/half-and-half): pretty finish + extra chocolate
Ingredient Substitution Notes
- Cereal: you can use another s’mores-style cereal or a graham-style cereal blend; keep the volume the same (8 cups) for best texture.
Recipe Tips
- Use low heat when melting marshmallows so the mixture stays soft and workable.
- Stir quickly once cereal goes in so everything coats evenly.
- Press firmly—this is the difference between neat bars and crumbly ones.
- If drizzling chocolate, microwave in short bursts to avoid seizing.
What to Serve With S’mores Cereal Bars
- Milk (classic)
- Hot chocolate or Chai Latte
- Fresh strawberries or bananas (nice with the chocolate)
- Party tray idea: serve with extra mini marshmallows and a small bowl of chocolate chips
Storage
The recipe recommends: store covered at room temperature.
Optional best-practice note (non-recipe): for best texture, these are usually nicest within a couple days, especially in humid kitchens.
Time-Saving Swaps
- Skip the drizzle (still great—fewer dishes)
- Line the pan with parchment for faster lift-and-slice cleanup (not required, just handy)
Leftover Uses
- Chop into bite-size cubes for a dessert snack mix
- Crumble over ice cream
- Pack as lunchbox treats
- Stack on a platter for party “grab and go” desserts

Final Thoughts

Indoor S’mores Cereal Bars
Ingredients
- 10.5 ounces miniature marshmallows , 10.5 oz bag (5½ cups)
- 1 cup mini milk chocolate chips (9 oz)
- 5 tablespoons butter or margarine
- 1 teaspoon vanilla
- 8 cups Malt-O-Meal S'Mores cereal , (1/2 bag)
Optional garnish
- 1/4 cup mini chocolate chips
- 1 tsp milk or half and half
Instructions
- Lightly spray or butter a 13×9-inch pan and set aside. In a large saucepan [paid link], melt the butter and bag of marshmallows over low heat. Stir until completely melted. Remove from heat; stir in vanilla.
- Pour in the cereal and chocolate chips into the saucepan [paid link]. With a large spoon, mix until coated with the melted chocolate mixture.
- With the back of a buttered spoon or oiled hands, press the mixture into the pan.
- For the optional garnish: Melt chocolate with milk in a microwave safe bowl for about 20 seconds. Stir until smooth. If not completely smooth, heat in microwave for another 10 seconds or so and stir again until smooth. Overheating the chocolate can cause it to seize up. Drizzle melted chocolate over the top with the tines of a fork or by placing the chocolate into a plastic sandwich bag and snipping off a corner of the bag and freehand piping it over the top of the cereal bars.
- Cool at least 1 hour or until firm. Store covered at room temperature.
Notes
- The Malt-O-Meal brand S’Mores cereal contains enough cereal to make a double batch of these bars. The extra chocolate bits and chocolate garnish may be easily omitted without any other changes to the recipe.
