There are days when you want the nostalgic taste of s’mores without building a fire or even turning on the oven. This no bake s’mores cake captures that classic combination of graham cracker, chocolate, and toasted marshmallow in perfect dessert layers that come together mostly in the fridge. My family goes wild for this cake at every summer birthday because it feels like a celebration in every bite.
I first tried out this recipe for a picnic when the weather was too stormy to light a campfire. It instantly brought back camp memories for all of us and now my friends request it for potlucks and special occasions.
Ingredients
- Semi-sweet or milk chocolate: finely chopped because high quality chocolate will melt smoothly and create a rich ganache
- Heavy cream: use fresh and full fat for the best creamy chocolate layers
- Large egg whites: at room temperature which whip up fluffiest when not cold
- Granulated sugar: to create glossy and sweet marshmallow meringue
- Cream of tartar: which helps stabilize and give structure to the meringue
- Pure vanilla extract: for real marshmallow flavor
- Graham crackers or digestive biscuits: choose sturdy whole crackers for strong layers and authentic taste
Step-by-Step Instructions
- Prepare the Pan:
- Line a square baking pan with parchment paper making sure to leave extra on the sides for easy lifting later Allow the pan to sit at room temperature while you prep the other elements
- Make the Chocolate Ganache:
- Place all the chopped chocolate into a heatproof bowl Heat the heavy cream just to a simmer in a small saucepan then pour it over the chocolate Let it sit undisturbed for three minutes to gently melt the chocolate Then stir slowly until completely smooth and glossy Cover and place this ganache in the fridge to thicken while you continue
- Prepare the Marshmallow Meringue:
- Combine the egg whites granulated sugar and cream of tartar in a large glass bowl Set the bowl over a saucepan with a few centimeters of barely simmering water Make sure the bowl does not touch the water Whisk constantly until the sugar dissolves and the mixture is thinner Remove from heat stir in vanilla then whip on high with mixer until stiff and shiny peaks form Save one heaped cup of this meringue in the fridge for decorating the top
- Begin Layering:
- Spread a very thin layer of the meringue in the base of your pan to keep the bottom from shifting Press down a single layer of graham crackers breaking as needed for an even fit
- Build Up with Layers:
- On top of the crackers spread a thick layer of meringue Next add another layer of crackers then a generous layer of chocolate ganache Continue in this order graham crackers then meringue then crackers then ganache until you finish with a top layer of chocolate ganache The cake should have six cracker layers and alternating meringue and ganache
- Chill and Set:
- Cover the whole pan tightly with wrap and refrigerate for at least twelve hours or overnight so the crackers soften and the flavors blend
- Finish and Serve:
- Take out your reserved meringue from the fridge and whip again if needed to fluff it Spread this across the top of the chilled cake Swirl it for texture then torch it with a kitchen torch for that campfire char Slide out the cake using the parchment to a cutting board slice and enjoy

My favorite part is swirling the marshmallow meringue on top and firing up the torch The smell alone takes me back to camping trips My kids always try to sneak extra toasted meringue from the bowl before I can spread it onto the cake
Storage Tips
Keep leftovers tightly wrapped in the fridge where they stay freshest for two days The cake can also be frozen but the toasted meringue will lose some of its texture If you know you want to freeze it only add the final meringue topping before serving
Ingredient Substitutions
