These no-bake smores bars capture the cozy nostalgia of a campfire treat right in your kitchen There is no need for flames or sticks—just layers of buttery graham crackers gooey marshmallows and glossy chocolate all coming together in irresistible squares that chill while you get on with your day

I remember making these late at night before a bake sale and my entire home smelled like chocolate and toasty marshmallows The leftovers disappeared before sunrise

Ingredients

  • Graham cracker crumbs: create a crunchy sturdy base For best flavor use fresh crackers and grind them fine
  • Unsalted butter: binds the base and marshmallow layer together Choose a quality butter for a richer taste
  • Granulated sugar: sweetens and helps compact the crust A fine texture blends best
  • Mini marshmallows: melt evenly ensuring a gooey middle Use fluffy and fresh marshmallows for the perfect pull
  • Semisweet chocolate chips: provide deep chocolate flavor you can swap for milk chocolate if you prefer it sweeter
  • Heavy cream: gives the chocolate layer a silky fudge texture Look for cream with minimal additives
  • Extra marshmallows and graham cracker pieces: add crunch and color on top Use the freshest pieces for best results

Instructions

Prepare The Pan:
Line your baking pan with parchment paper leaving enough to easily lift out the bars later This prevents sticking and makes cutting easier
Make The Graham Base:
Combine your graham crumbs melted butter and sugar in a bowl Mix thoroughly until the mixture resembles wet sand Press very firmly into the bottom of the pan so the base holds its shape and does not crumble
Melt The Marshmallows:
Place mini marshmallows and butter in a microwave safe bowl Heat in short bursts stirring after each until completely smooth and melted Quickly pour this over the graham layer and use a spatula to spread it evenly Let it set for a few minutes so it firms up slightly before adding the next layer
Make The Chocolate Layer:
In another bowl combine your chocolate chips with heavy cream Microwave at short intervals stirring until you get a glossy thick chocolate ganache Pour this carefully over the cooled marshmallow layer Spread gently for an even finish
Add The Topping:
Scatter extra marshmallows broken graham pieces and a sprinkle of chocolate chips over the freshly spread ganache Lightly press down with your hands so they stick into the chocolate as it sets
Chill And Slice:
Refrigerate the pan for about an hour or until the layers are well set and firm Use the parchment to lift the slab out then cut into neat bars with a sharp knife Serve chilled or let them sit at room temperature for a few minutes for a softer bite

Each bite brings back childhood memories for me My favorite part is always the marshmallow—it gets incredibly gooey and chewy after chilling Making these for family movie nights has become our tradition

Storage Tips

Store leftover bars in an airtight container in the refrigerator to keep the layers firm They stay fresh for several days so they are great to prep ahead Stack with parchment between layers if needed so they do not stick together

Ingredient Substitutions

Gluten free graham crackers can be swapped for the crust if you need an allergy friendly dessert Choose vegan marshmallows and dairy free chocolate plus plant butter and coconut cream for a fully plant based version Mix in peanut butter chips or white chocolate for a twist

Serving Suggestions

These bars taste great chilled but if you want extra gooeyness leave them out of the fridge for twenty minutes before serving I love to cut them into smaller pieces for potlucks or as a fun topping on bowls of ice cream You can even drizzle with melted peanut butter for an indulgent finish

Common Questions

→ How do I keep the bars from sticking when removing them from the pan?

Line the pan with parchment paper, leaving an overhang so you can lift the bars out easily after chilling.

→ How can I make this treat vegetarian-friendly?

Check that the marshmallows do not contain animal gelatin and use plant-based marshmallows if needed.
