What’s icebox cake?

Icebox cake isn’t actually frozen, even though it sounds like it should be! It’s a refrigerated, layered cake that became popular in the early 1900s. When the icebox, a non-electric refrigerator, became more common, food companies started to print icebox cake recipes on their labels and boxes. There are many variations, but the common elements include wafer cookies and a creamy filling. 

How long does it take to make S’mores Icebox Cake?

Let the fridge do the hard work for you! The cake needs to set in the refrigerator for at least six hours, so make sure to prepare this recipe in advance!

S’mores Icebox Cake Ingredients

Graham crackers

Choose your favorite honey graham crackers. They become the base “cake” layers for this icebox cake. You can even choose a gluten-free option. 

Cream cheese

Softened and whipped until fluffy, the cream cheese provides a smooth base for the filling.

Marshmallow Fluff

The sweet and sticky star of this dessert. The marshmallow fluff is gently folded into the cream cheese.

Heavy cream

Real whipped cream gets folded into the marshmallow fluff filling, to keep it light, airy, and totally heavenly. 

Vanilla extract

Adds extra depth and classic flavor to the whipped cream. 

Almond extract

The almond extract injects a little “toasted” and “nutty” flavor to the filling—sort of like a toasted marshmallow! 

Hot fudge sauce

Homemade or store-bought. Either will work great and should be at room temperature.  

Mini marshmallows

Sprinkle these on the top and torch them, for an authentic s’mores experience. Because let’s be honest: you can’t have s’mores without toasted marshmallows!

Constructing Your Masterpiece

S’mores icebox cake is built in a springform pan. You’ll layer the ingredients then store the cake in the refrigerator. After the dessert has set, simply release the springform in the pan and remove the sides of the pan from the icebox cake…just like a cheesecake! Voila.

Serving the Cake

Want to crank things up a notch? Serve the dessert cold and torch the marshmallows right before serving. If you don’t have a torch, you can put marshmallows in the oven to broil.

Then, enjoy the classic taste of s’mores, with an elevated twist.

Or, serve as-is for a hassle-free delicious dessert!

Ingredients

Scale

For the Icebox Cake:

  • 2 standard packages of Graham crackers
  • 8 oz cream cheese, softened
  • 14 oz marshmallow fluff
  • 2 cups heavy cream
  • 2 cups hot fudge sauce, slightly warmed to easily spreadable consistency but not hot
  • 2 cups mini marshmallows

Topping Ideas:

  • Additional mini marshmallows
  • Crushed graham crackers
  • Broken pieces of milk chocolate bar

Instructions

  1. In a bowl of an electric mixer, beat together the cream cheese and marshmallow fluff until smooth and creamy. In a separate bowl whip the heavy cream for about 4-5 minutes or until stiff peaks form. Use a rubber spatula to fold the whipped cream into the marshmallow fluff mixture until smooth and combined. 
  2. In the bottom of a springform pan start building your icebox layers by adding an even layer of graham crackers to the bottom of the pan. Breaking the graham crackers into halves or pieces to cover the bottom of the pan the best that you can.
  3. Add an even layer of marshmallow fluff filling, using half of the mixture. Next, evenly cover with a cup of mini marshmallows. Then, drizzle on a layer of hot fudge sauce using half of the sauce. 
  4. Repeat starting with the graham cracker layer until all ingredients are used and the pan is full ending with the hot fudge layer.
  5. After the last hot fudge layer garnish with toppings of your choice, such as some mini marshmallows, a sprinkle of crushed graham cracker, and milk chocolate pieces. 
  6. Gently cover and refrigerate for at least 6 hours or up to 1-2 days in advance.
