These Golden Grahams s’mores bars turn crunchy honey-cinnamon cereal into a chewy, no-bake snack with buttery marshmallow and pockets of chocolate. Cut the set mixture into squares for an easy party treat, lunchbox dessert, or make-ahead snack; the cereal brings plenty of crunch without needing a campfire.
Ingredients
- 4 tablespoons unsalted butter (57 g)
- 5 cups mini marshmallows, divided (250 g)
- 6 cups Golden Grahams cereal (210 g)
- 1 cup semisweet chocolate chips, divided (170 g)
- 1 teaspoon vanilla extract (5 ml)
- 1/4 teaspoon fine salt (1.5 g)
- 1/8 teaspoon flaky salt, optional for the top (about 0.5 g)
Instructions
- Line a 9-by-13-inch (23-by-33-cm) pan with parchment paper, leaving a little overhang on the long sides so you can lift the slab out later. Measure the cereal and divide the mini marshmallows: 4 cups (200 g) for the melted binder and 1 cup (50 g) to fold in near the end. Set aside 2 tablespoons (about 21 g) of the chocolate chips for the top; the rest go inside the bars.
- Put the butter in a large, heavy-bottomed saucepan and melt it over low heat. Add the 4 cups of marshmallows and stir steadily for about 3 to 5 minutes, until they are mostly smooth and glossy. Keep the heat low; marshmallows can scorch or turn tough if they are cooked hard. Take the pan off the heat and stir in the vanilla and fine salt.
- Let the melted mixture stand for 5 minutes, stirring once or twice. This short pause cools it enough that the chocolate chips are less likely to melt completely, while the marshmallow binder stays soft and easy to mix. If the mixture becomes stiff during this wait, return the pan to very low heat for a few seconds rather than adding liquid.
- Add the cereal to the saucepan in two or three additions. Fold gently with a sturdy spatula until the pieces are coated, scraping the bottom and corners as you go. Fold in the reserved 1 cup of mini marshmallows and the remaining chocolate chips. Work with a light hand so the cereal squares stay intact and the add-ins remain visible instead of being crushed or smeared.
- Transfer the mixture to the lined pan. Use a lightly buttered spatula or a piece of parchment to press it into an even layer, pressing just firmly enough to help the bars hold together. Avoid compacting it into a hard slab. Scatter the reserved 2 tablespoons of chocolate chips over the surface and press them in gently; add the flaky salt, if using.
- Leave the pan at a cool room temperature for 60 minutes, until the center feels set and the bars can be lifted without sagging. Lift the slab out using the parchment, place it on a cutting board, and cut it into 16 squares with a sharp knife. For cleaner edges, wipe the blade between cuts. If the bars are still sticky in the middle, give them another 10 minutes before slicing.
Tips
- Use fresh marshmallows. Older marshmallows can dry out and melt unevenly, leaving stubborn lumps in the binder. If the bag has been open for a while and the marshmallows feel firm or stuck together, use a fresh bag for a smoother mixture. Mini marshmallows melt quickly; standard-size marshmallows also work, but give them extra time over low heat and stir often.
- Keep the heat gentle. High heat may seem like a shortcut, but it can make the melted marshmallow mixture overly stiff as it cools. Remove the pan from the burner as soon as the binder is smooth. A few small marshmallow pieces will finish melting from the residual warmth while you stir.
- Make pressing easier. Marshmallow mixture sticks to bare hands and utensils. Lightly butter the spatula or press through parchment, and press evenly from edge to edge. Do not mash the cereal down; a light, even press gives the squares enough structure while preserving their crisp texture.
- Choose the right chocolate. Semisweet chips balance the sweet cereal and marshmallows. Milk chocolate makes a sweeter, softer-tasting bar, while dark chocolate gives a more pronounced contrast. If your kitchen is warm, keep the chips chilled until you fold them in so they hold their shape better.
Serving Suggestions
Serve the squares at room temperature, when the marshmallow binder is pleasantly chewy and the cereal still has some crunch. They work well on a dessert platter alongside fresh strawberries, apple slices, or a bowl of salty pretzels; those simple, less-sweet accompaniments balance the rich bars. For a casual gathering, cut them into smaller bite-size pieces and arrange them in paper muffin liners so guests can pick one up without getting chocolate on their fingers.
For lunchboxes or a snack table, wrap individual squares in parchment or place them in small airtight containers. They are sturdy enough to travel once set, although a hot car or sunny picnic table can soften the chocolate and marshmallow. At a party, keep the bars shaded and put out a few at a time rather than leaving the whole batch in direct sun. A glass of cold milk, cocoa, or coffee makes a simple pairing, depending on whether you are serving them to children or adults.
Variations
More campfire-style: Add 1/2 cup (about 30 g) of small graham cracker pieces with the cereal and use milk chocolate chips. The extra crumbs add a more obvious graham flavor, though they also make the bars a little more delicate, so press gently and let them set fully before cutting.
Peanut butter and chocolate: Stir 1/3 cup (85 g) creamy peanut butter into the melted butter and marshmallow mixture after taking it off the heat. Use 3/4 cup (about 128 g) chocolate chips rather than a full cup if you want the peanut flavor to come through. The finished bars will be richer and slightly softer. For a nut-free version, use a seed butter only if it is suitable for the people you are serving.
More crunch: Fold in 1/2 cup (60 g) roasted peanuts or 1/2 cup (about 50 g) toasted coconut with the chocolate chips. Chop larger nuts so they do not make the squares difficult to slice. Add these only after the mixture has cooled for 5 minutes, and keep the total additions moderate so the marshmallow binder can still hold everything together.
Change the chocolate finish: Instead of scattering chips on top, melt 1/4 cup (43 g) chocolate chips and drizzle them over the set slab. Let the drizzle firm before cutting. This gives a neater, thinner chocolate finish, but it adds a little waiting time and can make the tops stick together if you stack the bars before the chocolate has set.
Storage and Reheating
Because the bars contain melted marshmallow and are handled after cooking, refrigerate them within 2 hours. Store them in a single layer in an airtight container, with parchment between layers if stacking, for up to 5 days. The refrigerator keeps the chocolate from becoming messy, but it also firms the marshmallow and makes the cereal seem less crisp. For a softer bite, let a portion sit at room temperature for 15 to 20 minutes before serving.
These bars do not need reheating, and microwaving can melt the chocolate unevenly and make the marshmallow sticky. If you want to prepare them farther ahead, wrap individual squares tightly and freeze them in a freezer-safe container for up to 6 weeks. Thaw them in the refrigerator, still wrapped, then bring them toward room temperature before serving. Avoid leaving thawed bars out for more than 2 hours; return leftovers to the refrigerator.
Frequently Asked Questions
Can I make these bars without a stove?
Yes. Melt the butter and marshmallows in a large microwave-safe bowl in 20-second bursts, stirring well after each burst, until smooth. Use a roomy bowl because marshmallows puff as they heat, and stop as soon as the mixture is melted. Stir in the vanilla and salt, wait 5 minutes, then follow the folding and setting steps. Microwaves vary, so short bursts help prevent scorching.
Why did my bars turn hard?
The most common cause is cooking the marshmallows too long or over heat that is too high. Once the binder is heated past the point where it melts smoothly, it can set firm and make the finished bars tough. Pressing the mixture too firmly into the pan can also make it dense. Next time, use low heat, take the pan off as soon as the mixture is smooth, and press only enough to form an even layer.
Can I use large marshmallows instead of mini marshmallows?
Yes. Measure by volume or weight as listed, not by counting pieces, and cut large marshmallows into smaller pieces if you want them to melt faster. Keep the same total quantity: 4 cups (200 g) for the binder and 1 cup (50 g) to fold in. The larger pieces may take a little longer to melt, so stir patiently over low heat rather than turning up the burner.
Can I make Golden Grahams bars gluten-free or dairy-free?
Check the current cereal package carefully: Golden Grahams as sold may contain wheat ingredients, so the recipe is not gluten-free with that cereal. For a gluten-free adaptation, use a similarly sized certified gluten-free honey-graham cereal and check every label, including the chocolate and marshmallows. For dairy-free bars, use a plant-based butter and dairy-free chocolate chips; check the marshmallow label as well, since products vary.
How do I keep the chocolate chips from melting into the bars?
After melting the binder, let it stand off the heat for the full 5 minutes before mixing in the cereal and chips. Keep the chips cool until needed, and fold them in briefly rather than stirring vigorously. Some chocolate smearing is normal because the mixture is still warm, but these steps help retain distinct chocolate pockets. If you prefer completely defined pieces, use the drizzle variation and apply it after the slab has set.
Can I double the recipe?
Yes, but use two 9-by-13-inch (23-by-33-cm) pans rather than trying to press a double batch into one pan. A very deep layer is harder to mix evenly and takes longer to set. Melt the binder in a large pot with enough room to fold in the cereal, or make two batches if your saucepan is small. Divide the mixture promptly between the pans and allow each one the full setting time.
