Baking Tip: What is an Icebox Cake?
An icebox cake is a marvel of no-bake confectionery, relying entirely on the refrigerator, rather than an oven, to work its magic. This simple yet sophisticated dessert typically consists of layers of a creamy filling and store-bought cookies or wafers. As the cake chills overnight (or for several hours), the moisture from the creamy layers gradually softens the cookies, transforming them into tender, cake-like layers that are wonderfully moist and cohesive. The process is incredibly straightforward, making icebox cakes an ideal choice for bakers of all skill levels, especially during warmer months when oven-free desserts are highly desirable.
The beauty of icebox cakes lies in their versatility. They come in countless variations, utilizing a wide array of creamy fillings—from rich puddings and luscious mousses to sweetened whipped cream and cream cheese mixtures—paired with different types of cookies, such as graham crackers, chocolate wafers, gingersnaps, or shortbread. Some recipes call for whole cookies arranged in neat rows, while others might use crushed cookie crumbs to create a more uniform texture. They also vary in size, shape, and flavor profiles, adapting to almost any preference or occasion. There’s truly no single “right” way to create an icebox cake; the possibilities for customization are endless, allowing for both classic comforts and innovative flavor combinations. The hardest part, undoubtedly, is summoning the patience to wait for the cake to properly set in the fridge before diving in!

Ingredients
For the chocolate pudding: (see Note)
- 1 ¾ cup whole milk (415 ml)
- ⅓ cup granulated sugar (65 grams)
- ¼ cup unsweetened cocoa powder (20 grams)
- 3 tablespoons cornstarch (20 grams)
- Pinch of salt
- 2 large egg yolks
- 1 teaspoon vanilla extract
To assemble the icebox cake:
- 1 cup heavy whipping cream (237 ml)
- 7 ounce jar marshmallow cream (200 grams)
- 1 ½ cup mini marshmallows (65 grams)
- 1 sleeve graham crackers (approximately 20 squares, 150 grams)
Toppings:
- 1 cup heavy whipping cream (237 ml)
- 2 tablespoons granulated sugar
- 1 teaspoon vanilla extract
- Graham crackers , broken up
- Mini marshmallows
- Chocolate syrup
Instructions
To make the chocolate pudding:
-
In a medium saucepan over medium-low heat, whisk together the milk, granulated sugar, unsweetened cocoa powder, cornstarch, and a pinch of salt until the mixture is completely smooth and free of lumps. Gently heat, stirring occasionally, until the mixture just begins to steam and warms through.
-
In a separate medium bowl, lightly whisk the large egg yolks. While continuously whisking the egg yolks, slowly stream in about half of the warm milk mixture. This tempering step prevents the eggs from scrambling. Once combined, pour the tempered egg mixture back into the saucepan with the remaining milk mixture.
-
Return the saucepan to medium heat. Cook, stirring constantly with a whisk or spatula, until the pudding thickens to a consistency similar to Greek yogurt, which typically takes about 4-5 minutes. Immediately remove from heat and stir in the vanilla extract. Transfer the pudding to a clean bowl, cover the surface directly with plastic wrap to prevent a skin from forming, and chill in the fridge for at least 1 hour, or until thoroughly cooled.
To assemble the icebox cake:
-
In the bowl of a stand mixer fitted with a whisk attachment (or using a large bowl and a hand-held electric mixer), beat the heavy whipping cream and marshmallow cream together on medium-high speed until soft peaks form. Gently fold in the mini marshmallows. Be careful not to overmix.
-
Line a 9×5-inch loaf pan generously with plastic wrap, allowing excess wrap to hang over the sides for easy lifting later. Place a single layer of graham crackers on the bottom of the pan, breaking them as needed to fit snugly and cover the entire base. Spread an even layer of the marshmallow whipped cream over the graham crackers. Follow with a layer of the chilled chocolate pudding, spreading it smoothly.
-
Repeat the layering process: graham crackers, marshmallow whipped cream, and chocolate pudding. You should be able to create approximately three full layers. Finish with a final layer of graham crackers on top. Cover the pan tightly with the overhanging plastic wrap, ensuring the cake is well-sealed. Chill in the refrigerator overnight, or for a minimum of 8 hours, to allow the layers to meld and the graham crackers to soften to a cake-like consistency.
For the toppings:
-
When ready to serve, prepare the fresh whipped cream topping. In the bowl of a stand mixer fitted with a whisk attachment (or using a large bowl and a hand-held mixer), beat the heavy cream, granulated sugar, and vanilla extract on medium-high speed until medium peaks form.
-
Remove the top layer of plastic wrap from the chilled icebox cake. Place a serving platter or cutting board upside-down firmly on top of the loaf pan. Carefully but swiftly invert the entire assembly, so the cake now rests on the platter. Gently lift and remove the loaf pan, then peel away the remaining plastic wrap from the cake.
-
Generously cover the entire S’mores Icebox Cake with the freshly whipped cream. Decorate the top with broken graham crackers and additional mini marshmallows. For an authentic campfire touch, use a kitchen torch to lightly toast the mini marshmallows on top, working quickly to avoid melting the whipped cream beneath. Finish with an elegant drizzle of chocolate syrup. Slice and serve immediately.
-
Store any leftover S’mores No-Bake Icebox Cake tightly covered in the fridge for up to 5 days.
Notes
- For a quicker preparation, you can substitute the homemade chocolate pudding with one 3.5 oz package of instant chocolate pudding mix. Prepare it according to the package directions, and use it immediately in the assembly process without the need for prior chilling.
- If you plan to transport this delicious treat, perhaps to a potluck or picnic, consider serving it directly from the loaf pan. This eliminates the need for the additional whipped cream topping and makes it much easier to carry and serve on the go.
- This recipe was originally published in June 2014. Since then, I’ve refined and made a few minor adjustments to simplify the process and enhance the overall flavor, making it even more foolproof and delicious!
