S’mores Icebox Cake Recipe

Yields: 8-10 Servings

Prep Time: 20 minutes

Chill Time: At least 4 hours (preferably overnight)


Graham Cracker Layer

  • 1 box (about 14.4 oz) honey graham crackers (approximately 30-36 full sheets)

Chocolate Ganache

  • 1 cup heavy cream
  • 12 ounces semi-sweet chocolate chips (or milk chocolate if you prefer)

Marshmallow Whipped Cream

  • 2 cups heavy cream
  • 1 (7-ounce) jar marshmallow fluff (creme)

Garnish (Optional)

  • Mini marshmallows
  • Chocolate pieces or shavings
  • Graham cracker crumbs


  • 9×5 inch loaf pan
  • Medium saucepan
  • Large mixing bowl
  • Whisk or hand mixer
  • Rubber spatula


Prepare the Pan: Line your loaf pan with plastic wrap, leaving some overhang on the sides for easy removal of the cake.

1. Make the Chocolate Ganache

  • Heat the heavy cream in a medium saucepan over medium heat until it just begins to simmer.
  • Remove the pan from the heat and stir in the chocolate chips. Let stand for a minute to melt, then whisk until smooth and glossy.
  • Allow the ganache to cool slightly before using.

2. Make the Marshmallow Whipped Cream

  • In a large bowl, beat the heavy cream with a whisk or hand mixer until stiff peaks form.
  • Gently fold in the marshmallow fluff until well combined.

3. Assemble the Icebox Cake

  • Place a single layer of graham crackers in the bottom of the prepared loaf pan, breaking crackers as needed to fit.
  • Spread half of the marshmallow whipped cream over the graham crackers.
  • Drizzle about 1/3 of the cooled chocolate ganache over the marshmallow layer.
  • Repeat with another layer of graham crackers, the remaining marshmallow cream, and another drizzle of chocolate ganache.
  • Finish with a final layer of graham crackers.

4. Chill

  • Cover the pan tightly with plastic wrap and place in the refrigerator for at least 4 hours, but ideally overnight. This allows the graham crackers to soften and the flavors to meld.

5. Serve

  • When ready to serve, use the plastic wrap overhang to lift the cake out of the pan.
  • Garnish with mini marshmallows, graham cracker crumbs, and chocolate shavings or pieces, if desired.
  • Slice and enjoy!


Toast the marshmallows: For an extra s’mores flavor, toast some mini marshmallows under the broiler for a few seconds before garnishing.

Make it your own: Add a touch of peanut butter to the whipped cream or substitute some of the graham crackers with chocolate graham crackers.

Storage: Store leftover cake covered in the refrigerator for up to 3 days.
