An over-the-top s'mores icebox cake complete with marshmallow whipped cream, soft chocolate ganache, graham crackers and toasted marshmallows!
I have always loved making icebox cakes. The simplicity and flavor combinations are pretty much endless when it comes to them! I had so much coming up with this one. What's better than s'mores in the summertime? You can even make this in the cooler months to get your s'mores fix. What exactly is an icebox cake, you ask? It's a no bake dessert that involves layering graham crackers or cookies with different fillings that will then get refrigerated overnight. The cracker/cookie layer gets super soft and cake-like after absorbing moisture from the marshmallow cream.
Why you'll love this recipe
- Icebox cakes are SO easy to make and only require a few simple ingredients.
- Who doesn't love s'mores?! Make this recipe without the use of a campfire OR even an oven on those warm days.
The other layers consisted of the usual graham crackers, but the whipped cream layers I had to figure out how I would get the marshmallow flavor in there. I decided to add marshmallow creme to the whipped cream and fold in some mini marshmallows for fun. They get nice and soft so you barely know they are there.
- Honey graham crackers: You will use an entire 14.4 oz box of graham crackers for this dessert.
- Heavy cream: You will use heavy cream to make both the whipped cream and chocolate ganache.
- Marshmallow creme: Aka marshmallow fluff! Adds delicious marshmallow flavor to the whipped cream.
- Mini marshmallows: These get folded into whipped cream and sprinkled on top of the finished icebox cake. Pro tip: [safely] with a culinary torch, toast the top of the marshmallows to really take this dessert over the top!
- Semi-sweet chocolate chips: Mixed with hot heavy cream, you get chocolate ganache!
- Hershey's chocolate bars: optional! I like to add a few pieces to the top of my icebox cake to finish it off and this really helps with enhancing that s'mores flavor!
Substitutions & Variations
- Cracker/cookie Swap: Try substituting with chocolate graham crackers for a different flavor. Instead of graham crackers, you can try other types of cookies to add different flavors. For example, chocolate chip cookies or Oreo cookies. These will take away the authentic s'mores flavor, but would still taste delicious!
- Nutty: Consider adding some peanut butter to the marshmallow whipped cream mixture for a fluffernutter version. Sprinkle crushed peanuts between the layers and on top of the cake.
- Miniature Size: Instead of assembling a large cake, create individual portions by using small jars or glasses. Layer the ingredients accordingly and serve the mini S'mores Icebox Cakes as individual desserts. These would be so fun for a party!
How to make a s'mores icebox cake
- Prepare whipped cream and fold in marshmallow creme and marshmallows.
- Prepare chocolate ganache and allow to cool completely.
- To assemble: Spread a small amount of whipped cream in the bottom of your baking dish. Layer with graham crackers and break apart as needed to create a single layer. Top with ⅓ of marshmallow whipped cream and then ½ of chocolate ganache. The ganache will be topped with graham crackers and you will start the layers again until you reach the top of the pan. The last layer will be whipped cream.
- If you have a bit of chocolate ganache left, you can drizzle it on top. You will end up with three layers of graham crackers, three layers of whipped cream and two layers of chocolate. Cover and chill for four hours or overnight.
Before serving, top with crushed graham crackers, pieces of Hershey's chocolate bars (or chocolate chips) and mini marshmallows.
Toasting the marshmallows slightly with a culinary torch really takes this dessert over the top and really give it that s'mores flavor!

S’mores Icebox Cake
- 24 honey graham crackers
Marshmallow Whipped Cream Layer
- 4 cups heavy cream
- 16 oz marshmallow creme
- 3 cups mini marshmallows
- 3 cups heavy cream
- 5 cups semi-sweet chocolate chips
- 1 chocolate bar broken into smaller pieces, optional for garnish
- Beat heavy cream until soft peaks are formed with a hand mixer or your stand mixer fitted with the whisk attachment. Beat in marshmallow creme. Fold in marshmallows by hand with a rubber spatula.
- Measure out chocolate chips and place in a large bowl. In a large measuring cup, heat heavy cream in the microwave for 3 minutes. Alternatively, you can heat heavy cream on the stovetop until almost boiling. Pour hot cream over chocolate chips and give them a little shake to distribute evenly on top of them. Allow to sit for one minute, then start whisking from the center-outward until smooth. This may take some time. Allow to cool completely before assembling icebox cake.
- Assembly: Spread a small amount of the whipped cream layer in the bottom of a 9x13 pan. Layer with graham crackers and break apart as needed to create a single layer. Top with ⅓ of marshmallow whipped cream and then ½ of chocolate ganache. The ganache will be topped with graham crackers and you will start the layers again until you reach the top of the pan.
