Easy S’Mores Bars are a perfect summer treat made with just five ingredients. A buttery graham cracker crust, a melted chocolate layer, and toasted mini marshmallows combine to deliver classic s’mores flavor without a campfire. These bars are make-ahead friendly and freeze well, making them ideal for parties or a simple weeknight dessert.

These bars are quick and straightforward to prepare. They work great for backyard barbecues, potlucks, or any gathering where you want a crowd-pleasing dessert. Make a full pan to feed a group, or scale down for smaller servings. For a single-serve option, consider a mini version made in a small ramekin.
Ingredients for S’Mores Bars:
You need just five simple ingredients to make these gooey, chocolatey bars:
- Graham cracker crumbs – Use store-bought crumbs or crush graham sheets in a bag with a rolling pin until fine.
- White granulated sugar – A small amount helps bind and sweeten the crust.
- Butter – Melted butter holds the crust together and adds richness.
- Hershey’s chocolate bars – Traditional s’mores bars work well, but you can substitute chocolate chips or another chocolate bar if preferred.
- Mini marshmallows – They toast quickly and create the classic marshmallow topping.

How to Make S’Mores Bars
Follow these simple steps to assemble and bake the bars:
- Make the graham cracker crust – Combine graham cracker crumbs, sugar, and melted butter until the mixture resembles wet sand. Press evenly into a foil-lined and greased 9×13-inch pan. Bake until the edges turn golden.
- Add the chocolate layer – Arrange the chocolate bars across the warm crust. Return the pan to the still-warm oven for a minute or two to soften the chocolate, then gently spread it smooth.
- Top with marshmallows – Cover the melted chocolate with mini marshmallows in a tight layer. Broil briefly until the marshmallows are golden brown — this happens quickly, so watch them closely.





How to Cut into Squares:
For clean slices, warm a sharp knife with hot water, wipe it dry, and slice. Repeat warming and wiping between cuts to prevent the marshmallow from sticking and tearing the bars.

Leftovers, Storage, and Freezing
Storage: Store leftover bars in an airtight container for up to 5 days. Place parchment or wax paper between layers to prevent sticking. Refrigeration keeps them fresher longer, though they can be kept at room temperature if eaten within a day or two. Bring chilled bars to room temperature before serving for the best texture.
Freezing: These bars freeze well for up to 3 months. Layer parchment between pieces and use a freezer-safe container. Thaw overnight in the refrigerator, then let come to room temperature before serving.

Recipe Notes and Tips:
- Clean cutting: Reheat and wipe your knife between cuts to avoid sticky, uneven slices.
- Watch the broiler: Marshmallows toast very quickly under the broiler. Keep a close eye to avoid burning.
