Sโmores Icebox Cake
Iโm sโmores obsessedโif itโs sโmores-themed (Sโmores Bars, Sโmores Cookies, Sโmores Muddy Buddies) Iโm all in. After making a cookie icebox cake I loved, a sโmores version was a no-brainer!
These bars arenโt the hot, gooey, straight-off-the-fire kind of treat. Instead, they pack all the best sโmores flavors into the tastiest no-bake cake.
Thatโs rightโno oven, no campfire, and best of all, itโs served straight from the fridge!
Sโmores Icebox Cake Components
There are four main elements to this cake:
- Graham crackers
- Chocolate ganache filling
- Marshmallow whipped cream
- Optional: Meringue topping
Iโll break down each of these elements below!
Graham Crackers
The graham crackers are what become thin, cake-like layers in this dessert after absorbing moisture from the marshmallow cream.
For this Sโmores Icebox Cake, we use an entire box (14.4 oz.) of graham crackers. Since the crackers are the main flavor, be sure to use a flavorful box of graham crackers you enjoy. I love Honeymaidยฎ honey-flavored graham crackers best (not sponsored).ย
Chocolate Ganache Filling
The chocolate ganache filling has only two ingredients: chocolate and heavy cream.
- Use good-quality chocolate chips like Ghirardelliยฎ or Guittardยฎ for better flavor and melting. Cheaper ones can feel waxy and wonโt melt as smoothly.
- Use heavy creamโmilk wonโt get thick enough.
- Pour the hot cream over the chocolate, cover the bowl, and let it sit for 5 minutes. This helps melt the chocolate before you stir.
- Let the ganache cool a little before mixing it with the marshmallow whipped creamโif itโs too warm, it can change the texture.
Marshmallow Whipped Cream
- This whipped cream is fast with a stand mixerโhand mixers work too, just need more time.
- You just need heavy cream, powdered sugar, vanilla, and marshmallow fluff. I use Jet-Puffedยฎโrun a spoon under hot water, dry it, then scoop out the fluff.
- Beat until stiff peaks form, then itโs ready for the cake.
Quick Tip
If you donโt have access to marshmallow fluff, you can try making your own.
Optional Sโmores Icebox Cake Topping: Meringue
Once the cake is cold, you can eat it as is or add a meringue topping.
I love the flavor and soft texture the meringue adds, especially when itโs toastedโit looks like it came from a fire. It takes a little more work, so itโs up to you.
If you add it, use a kitchen torch to toast the meringue. Hold the torch a few inches away and move it aroundโit toasts fast!
Quick Tip
A kitchen torch is super useful! I use mine for Crรจme Brรปlรฉe, Cheesecake Bars, and Sโmores Pizookie. Itโs great for melting cheese, roasting peppers, and browning toppings fast.
Sโmores Icebox Cake Tips
- Use a 9ร9-inch panโthis cake wonโt work in an 8ร8 or smaller. The 9ร9 gives a full cake and helps the graham crackers fit evenly with fewer cracks.
- Line the dish with parchment paper and leave some extra hanging over the sides. That way, you can lift the cake out easily and slice it cleanly.
- Use a sharp knife and make clean cuts. Run it under warm water and wipe it off each time.
- Add something extra on top if you want! Try mini chocolate chips or chocolate curls to make it look nicer.
Quick Tip
Chocolate curls are so easy to make! Hereโs how:
- Use a chocolate bar โ we like to use a Lindtยฎ Dark Chocolate Bar with Sea Salt (not sponsored).
- Unwrap the bar and, using a vegetable peeler, peel down the side of the bar right on top of the cake pieces.
Storage
Sโmores Icebox Cake Storage
This Sโmores Icebox Cake is a great make-ahead dessert! In fact, it relies on being made ahead so the graham cracker layer can sufficiently soften! This cake is best eaten on days 2,3, or 4 and after that, it does begin to become a bit watery. Keep the cake in the fridge and serve it directly from the fridge. Return any leftovers promptly to the fridge.
This cake isnโt a great candidate for freezing and thawing โ there is so much dairy (heavy whipping cream) in it that it can become grainy and watery.

Equipment
- Stand mixer fitted with whisk attachment
- 9 x 9-inch baking pan see note 1
Ingredients
- 1 (12-ounce) bag semi-sweet chocolate chips about 2 cups, see note 2
- 3 cups heavy cream divided
- 2 tablespoons powdered sugar
- 1/2 teaspoon vanilla bean paste or 1 teaspoon vanilla extract, optional
- 1 (7-ounce) container marshmallow creme see note 3
- 1 (14.4-ounce) box honey graham crackers
- 2 large egg whites
- 1/2 cup granulated sugar
- 1/4 teaspoon cream of tartar
Instructionsย
- Pour chocolate chips in a large, heat-safe bowl. Scald 1 cup (240g) of the heavy cream (I add it to a glass measuring cup and microwave for 45โ90 seconds). Pour the hot heavy cream over the chocolate chips and cover the bowl with a clean lid (so no heat escapes). Let stand 5 minutes, then stir until smooth. This may take a few minutes. If needed, heat the mixture in the microwave in bursts of 10 seconds, stirring in between for 10 seconds until the chocolate mixture is completely smooth. Set aside at room temperature. (Ganache needs to be completely cooled to room temperature before adding to the cake or it will affect the texture of the marshmallow cream!)
- Pour remaining 2 cups (480g) heavy cream, powdered sugar, and vanilla in the base of a stand mixer fitted with a whisk attachment. Beat on low for 30 seconds to combine and gradually increase until at full speed. Beat, watching carefully, until soft peaks form (about 2โ4 minutes). Add all the marshmallow fluff and slowly beat to combine. Increase the speed to medium high until ingredients are combined and peaks are firm (about 30 seconds up to 1 minute). Set aside.
- Line a 9ร9-inch baking pan with parchment paper (helps bars come out nicely). Spread a tiny bit of the marshmallow cream on the bottom (just enough to hold graham crackers in place). Spread an even layer of graham crackers and 1/4th of the marshmallow cream on top. Smooth with the back of a spoon into an even layer. Add 1/3 of the room-temperature chocolate ganache. Smooth with a table knife into an even layer. (This takes some patience!) Add another layer of graham crackers, 1/4th of the marshmallow mixture, and 1/3 of the chocolate mixture. Add another layer of graham crackers, 1/4th of marshmallow mixture, and remaining 1/3 of chocolate. Add 1 last layer of graham crackers and the last 1/4th of the marshmallow mixture. You should be at the top of the pan. Cover the pan tightly and place in the fridge for at least 8 hours and preferably 12 hours.
- Optional Meringue: Place egg whites, sugar, and cream of tartar in a heatproof bowl. Set the bowl in a pot filled with 2 inches of simmering water over medium heat. Donโt let the bowl touch that water. Whisk constantly with a whisk until sugar is dissolved completely and the mixture has become bright white. (You can tell the sugar has dissolved by pinching off some of the mixture and rubbing it between your fingers, if you can feel a lot of sugar granules, keep mixing!)
- Transfer to a stand mixer (or use a hand mixer) and beat until stiff peaks form, about 5 minutes at high speed. Using a spatula, add dollops of the meringue all over the top of the cake. Gently coax the meringue to top the cake with the back of a spoonโthis takes some patience to not lift up the top layer! Use a fork to run over the top, creating small rough ridges and peaks. If you have a kitchen torch, singe the peaks until lightly browned (move the kitchen torch along the meringue quicklyโit will toast it very fast).
- Use the overhang of parchment to carefully remove bars from pan onto a cutting board. Use a sharp knife, run the knife under warm water, dry on a kitchen towel, and make decisive cuts. Repeat this process for each cut made.
