There’s not many things that come close to the indulgence of chocolate, graham cracker and marshmallow. It’s an iconic classic and today we’re going to take it up a notch with homemade S’more Bars.
The recipe takes a few extra steps, but it’s totally worth it! The bars have a grain-free graham cracker cookie crust, fudgy chocolate brownie middle and are topped with homemade marshmallow fluff. These S’more Bars are incredibly rich and can be cut into 16 squares for the perfect sweet bite.
S’more Bars (Gluten-Free)

Ingredients
Units
For the crust:
- 1/2 recipe of grain-free graham crackers
- 4 tablespoons coconut oil, melted
- 1 recipe of fudgy brownies
- 1 1/4 cups maple syrup
- 1/8 teaspoon Celtic sea salt
- 2 large egg whites
- 1/4 teaspoon cream of tartar
- 2 teaspoons vanilla extract
Instructions
- Preheat the oven to 350 degrees F and adjust the rack to the middle position. Line an 8×8″ baking pan with two pieces of parchment paper (place two sheets of parchment paper perpendicular to each other in pan, pushing paper into the corners).
- Place the graham crackers and melted coconut oil in the bowl of a food processor. Pulse until crackers are finely ground and are moist. Pour the cracker mixture into the prepared pan. Using your hands, press the crumbs to make an even layer. Bake for 10 minutes.
- Spoon fudgy brownie batter over graham cracker crust and bake for 25 minutes. Cool completely.
- Place the maple syrup and the salt in a medium sauce pan and bring to a boil over high heat. Continue boiling until the mixture reaches 240°F on a candy thermometer. While maple syrup is boiling, place the egg whites and cream of tartar in the bowl of a stand mixer fitted with a whisk attachment. Whip the egg whites to soft peaks on medium speed. (You should have the egg whites whipped and ready, waiting for your syrup to be drizzled in. If they’re whipping faster than your syrup is coming to temperature, just stop the mixer until the syrup is ready.)
- When the syrup reaches 240°F, reduce the mixer speed to low and slowly drizzle about 2 tablespoons of syrup into the egg whites to warm them. Slowly pour in the rest of the syrup (it should take about 1 1/2 minutes to add all of the syrup). Increase the speed to medium-high and whip for 7 minutes, until the marshmallow crème is stiff and glossy. Add the vanilla and whip an additional 2 minutes.
- After bars have baked and cooled, hold onto the overhanging parchment paper and gently lift the brownies out of the pan. Place them to a cutting board. Pour the marshmallow fluff on top of brownies and spread evenly. To cut, dip a knife in hot water, wipe with a clean cloth and then slice. Repeat. Serve.

These look amazing, Carrie! I want to make them right now!!!
Oh yum! We are making these tomorrow. I can hardly wait! S’more gratitude for you once again!
So how much vanilla do you use? It’s not listed in the ingredients of the marshmallow layer, but noted in instructions. Thanks.
Stephanie, Info on the vanilla is noted in the last sentence of the fifth paragraph.
These look so delicious and I can’t wait to make them. I just wanted to know how much is half of a recipe of graham crackers? Do you have a recipe for graham cracker crust so I can figure out how much graham crackers I need? Or what the final amount of of graham should be.
For a graham cracker crust, you can either make just half of the recipe, or make the full recipe and divide the crackers in half. Then you can place the crackers in a food processor with about 4 tablespoons melted butter, process until finely ground and press into the bottom of your pie dish.
Can the marshmellow be done with an egg sub? (allergic)

Hi,
I am allergic to dairy, so I used coconut oil in place of butter. Yum!
Can you make these ahead and keep in the fridge? In going on,a camping trip and would love to bring these!
The marshmallow topping might start to weep a bit, if they are stored in the fridge for too long. I’d make the bars, and then put the marshmallow topping in a separate container and then top the bars with the marshmallow before serving.
Do you think I could pipe this marsh mellow like a frosting?
The marshmallows are too thick to pipe like a frosting, but you can use it like a frosting. I’ve done that before with my grain-free chocolate cake recipe and it was divine!
Thank you so much for your recipes. I / we really do appreciate them. Can’t wait to try the smores recipe!
Thank you!
