No-Bake S’mores Icebox Cake Recipe

You’ve just died and gone to s’mores heaven — layers of graham crackers, chocolate pudding and marshmallow whipped cream chilled together into one luscious no-bake icebox cake. This easy, no-bake dessert captures all the flavors of a campfire s’more in a simple, make-ahead treat that’s perfect for warm-weather gatherings, potlucks, or an irresistible weeknight dessert.

Everyone is sure to love this no-bake s'mores icebox cake!

Classic s’mores are hard to improve on, but this icebox cake brings that familiar combination—crunchy graham crackers, silky chocolate and pillowy marshmallow—into an easy, layered format. Rather than roasting marshmallows over a flame, the marshmallow component becomes a fluffy whipped cream fold that sets up in the refrigerator and softens the crackers into cake-like layers.

This version is the one I keep coming back to. I’ve made it many times over the years and it’s always a crowd-pleaser. Once assembled, the cake needs several hours in the fridge so the layers meld and the graham crackers soften; the wait is worth it. When guests ask for the recipe at barbecues or potlucks, I’m always happy to share it.

S'mores No-Bake Icebox Cake is a quite the crowdpleaser!

baking tip: What is an icebox cake?

An icebox cake is a no-bake dessert that sets up in the refrigerator. Layers of cookies and creamy filling chill together, which softens the cookies into tender, cake-like layers while the filling firms up. They’re simple to assemble and ideal for make-ahead entertaining.

Variations abound: some recipes use whole cookies, others use crumbs, and fillings range from pudding to whipped mascarpone or flavored creams. The method is flexible and forgiving.

Ingredients

For the chocolate pudding (see notes):

  • 1 ¾ cup whole milk (415 ml)
  • ⅓ cup granulated sugar (65 g)
  • ¼ cup unsweetened cocoa powder (20 g)
  • 3 tbsp cornstarch (20 g)
  • Pinch of salt
  • 2 large egg yolks
  • 1 tsp vanilla extract

To assemble the icebox cake:

  • 1 cup heavy whipping cream (237 ml)
  • 7 oz jar marshmallow cream (200 g)
  • 1 ½ cup mini marshmallows (65 g)
  • 1 sleeve graham crackers (about 20 squares, 150 g)

Toppings:

  • 1 cup heavy whipping cream (237 ml)
  • 2 tbsp granulated sugar
  • 1 tsp vanilla extract
  • Broken graham crackers, mini marshmallows and chocolate syrup for garnish

Instructions

To make the chocolate pudding:

  • In a medium saucepan over medium-low heat combine the milk, sugar, cocoa and cornstarch with a pinch of salt, whisking until smooth. Heat until the mixture begins to steam, stirring to prevent scorching.
  • Whisk the egg yolks in a medium bowl. Slowly temper the yolks by adding a small stream of the hot milk mixture while whisking constantly. Once combined, return everything to the saucepan.
  • Cook over medium heat, stirring constantly, until the pudding thickens, about 4–5 minutes. Remove from heat, stir in the vanilla, then chill the pudding in the fridge for at least 1 hour.

To assemble the icebox cake:

  • In the bowl of a stand mixer fitted with a whisk attachment (or using a hand mixer), beat the marshmallow cream with 1 cup heavy cream until soft peaks form. Fold in the mini marshmallows.
  • Line a 9×5-inch loaf pan with plastic wrap. Place a row of graham crackers on the bottom, breaking pieces as needed to fit. Spread a layer of marshmallow whipped cream over the crackers, then add a layer of chilled chocolate pudding.
  • Repeat the layers until the pan is full (about three layers), finishing with a final row of graham crackers. Cover with plastic wrap and chill overnight or at least 8 hours to allow the layers to set and the crackers to soften.

For the toppings:

  • Beat the remaining 1 cup heavy cream, sugar and vanilla to medium peaks. Remove the plastic wrap from the chilled cake. Invert the loaf pan onto a serving platter and lift off the pan and plastic.
  • Cover the cake with whipped cream, then sprinkle with broken graham crackers and mini marshmallows. If you have a kitchen torch, carefully toast the marshmallows for a campfire flavor, working quickly so the whipped cream doesn’t melt. Drizzle with chocolate syrup.
  • Store leftovers tightly covered in the refrigerator for up to 5 days.

Notes

  • For a shortcut, substitute one 3.5 oz package of instant chocolate pudding mixed according to package directions; no chilling required before assembly.
  • If you need to transport the cake, you can assemble and serve it from the pan and skip the decorative toppings.
  • This recipe is flexible — use more or fewer marshmallows or adjust the layers to fit your pan size.
