S’more Ice Cream Cake

There is a reason the s’more has been a crowd favorite for generations. Crispy graham cracker, rich melted chocolate, and a gooey toasted marshmallow — it is one of the most perfect flavor combinations in the entire dessert world. Now imagine all of that in the form of a stunning, layered ice cream cake.

This S’more Ice Cream Cake is the kind of easy dessert recipe that looks like it came from a bakery window but is entirely no-bake and no-churn. It is the ultimate summer dessert table centerpiece, and it is every bit as yummy as it sounds.

Why You’ll Love This Easy No-Bake S’mores Dessert

This cake checks every single box a great summer easy dessert recipe needs to check.

First, there is absolutely no baking required. The two ice cream layers are no-churn — meaning no ice cream machine, no custard base, and no complicated technique. Just whipped cream folded into a flavored sweetened condensed milk base, which freezes into an incredibly creamy, scoopable ice cream every single time.

Second, every layer is intentional and delicious. The buttery brown sugar graham cracker crust brings the campfire s’more crunch. The toasted marshmallow ice cream — made with real broiler-toasted marshmallows — delivers that nostalgic, slightly smoky sweetness that makes a s’more a s’more. The double-chocolate ice cream layer and the silky homemade fudge sauce handle the rich, indulgent chocolate element. And the chocolate whipped cream frosting pulls the whole thing together in a smooth, beautiful finish.

Third, this cake is a make-ahead dream for anyone entertaining a crowd. It needs to freeze for several hours before serving, which means the hard work is done well in advance and you are free to enjoy the party.

Common Mistakes — And How to Avoid Them

Leaving the Broiler Unattended

Toasting marshmallows under the broiler is one of the most important steps in this recipe — and one of the riskiest if you walk away. Marshmallows go from beautifully golden to completely black and burnt in a matter of seconds under a hot broiler. Stay at the oven with the door cracked and watch them closely the entire time. If you prefer a safer approach, preheat the oven to 400°F and toast the marshmallows for 3 to 5 minutes instead — slower but far more forgiving.

Skipping the Food Processor for the Marshmallow Ice Cream

Toasted marshmallows are extraordinarily sticky, and trying to mix them into sweetened condensed milk by hand is an exercise in frustration. A food processor or blender is the right tool here — it breaks the marshmallows down completely and creates a smooth, evenly flavored base. If you do not have either, microwaving the marshmallow and sweetened condensed milk mixture for 10 to 15 seconds will loosen it enough to stir together.

Skipping the Plastic Wrap Lining

Lining your cake pans with plastic wrap is a non-negotiable step. Once your ice cream layers have frozen solid, the plastic wrap is what allows you to lift them cleanly out of the pan for assembly. Without it, you are either chiseling ice cream out of a metal pan or running warm water over the outside hoping for the best — both options risk damaging the clean, beautiful layers.

Not Chilling Long Enough Before Slicing

Patience is the secret ingredient in every ice cream cake recipe. After full assembly and frosting, the cake needs at least one full hour in the freezer before cutting — and longer is genuinely better. A cake that has not chilled long enough will smash and slide when you slice into it, destroying the layers you worked so hard to build. When it is time to cut, run a sharp knife under hot water and wipe it clean between each slice.

Key Ingredients for S’more Ice Cream Cake

Regular Marshmallows (for the Ice Cream)

Eighteen regular-sized marshmallows get toasted under the broiler until golden and slightly charred, then blended with sweetened condensed milk to form the base of the marshmallow ice cream. The toasting is what makes this ingredient extraordinary — it transforms plain marshmallows into something with depth, smokiness, and that unmistakable campfire flavor that defines a true s’more experience.

Sweetened Condensed Milk

The base of both no-churn ice creams. Sweetened condensed milk provides the sugar, the creaminess, and the structure that allows no-churn ice cream to freeze without the crystalline, icy texture that plagues homemade ice creams made with other methods. One can is divided between the two ice cream layers, making it an efficient and simple ingredient.

Milk Chocolate

Both melted milk chocolate and unsweetened cocoa powder go into the chocolate ice cream base, creating a double dose of chocolate flavor. Using both gives the ice cream a complex chocolate taste — the cocoa provides depth and slight bitterness, while the melted milk chocolate contributes creaminess and sweetness. Chopped milk chocolate pieces also top the finished cake as decoration.

Semi-Sweet Chocolate Chips (for the Fudge Sauce)

Just three ingredients — chocolate chips, corn syrup, and heavy cream — come together to make a fudge sauce that is smooth, glossy, and deeply chocolatey. The corn syrup keeps it from seizing and gives it a beautiful pourable consistency even after chilling. Half the sauce goes beneath the marshmallow ice cream layer; the other half is poured over the graham cracker crumbs in the middle of the cake.

Graham Crackers and Brown Sugar

Crushed graham crackers combined with melted butter, brown sugar, and a dash of cinnamon form two crispy crust layers — one at the very base of the cake and one pressed between the two ice cream layers. They provide the crunchy, campfire-classic element that anchors the entire s’mores flavor profile. The brown sugar deepens the graham flavor and adds a subtle caramel note.

Heavy Cream — Three Ways

Heavy cream is the workhorse of this recipe. It is whipped and folded into both ice cream bases, it is heated to make the fudge sauce, and it is whipped again — with sifted cocoa powder and powdered sugar — to make the chocolate whipped cream frosting that coats the outside of the cake. Always start with cold heavy cream and a chilled bowl for the fastest, most stable whip.

How to Make S’more Ice Cream Cake

1. Line a deep 6-inch springform pan (at least 3 inches deep) with plastic wrap. Combine the graham cracker crumbs, brown sugar, melted butter, and cinnamon. Press half of the mixture firmly into the base of the pan.
2. Make the fudge sauce: place the chocolate chips and corn syrup in a bowl. Heat the heavy cream in the microwave until it just begins to simmer, then pour it over the chocolate. Let sit for a few minutes, then stir until completely smooth. Pour half the fudge sauce over the graham cracker base and freeze for at least 30 minutes.
3. Arrange the regular marshmallows on a baking sheet and toast under the broiler, watching constantly, until golden brown. Remove from the oven. Blend the toasted marshmallows with 7 ounces of sweetened condensed milk in a food processor until completely smooth.
4. Melt the milk chocolate in a microwave-safe bowl. Stir in the remaining 7 ounces of sweetened condensed milk and the cocoa powder until completely smooth.
5. Whip the 2 cups of heavy cream in a chilled bowl until stiff peaks form. Fold one cup of whipped cream into the marshmallow base to lighten it, and another cup into the chocolate base. Divide the remaining whipped cream evenly between both mixtures and fold gently until just combined.
6. Pour the marshmallow ice cream over the chilled fudge layer and smooth the top. Sprinkle the remaining graham cracker mixture evenly over the marshmallow layer, then spread the remaining fudge sauce on top. Freeze for at least 4 hours.
7. Line a second 6-inch pan with plastic wrap. Pour the chocolate ice cream in, smooth the top, and freeze for at least 4 hours.
8. Using the plastic wrap, lift the marshmallow layer out of the pan and place it graham cracker side down on a serving plate. Lift the chocolate ice cream layer and place it on top. Return the assembled cake to the freezer.
9. Make the chocolate whipped cream frosting: sift the cocoa powder into the powdered sugar and stir together. Whip the heavy cream to soft peaks, then add the vanilla and the cocoa-powdered sugar mixture. Continue beating to stiff peaks.
10. Working quickly, apply a thin first coat of chocolate whipped cream all over the cake as a crumb coat. Freeze for 15 minutes, then apply a smooth second coat. Return to the freezer for at least 15 more minutes.
11. Pipe a decorative border along the top edge using the remaining chocolate whipped cream. Garnish with milk chocolate pieces, graham cracker squares, and toasted mini marshmallows. Freeze for at least 1 hour before slicing and serving.

Variations and Tips for the Best S’more Ice Cream Cake

Make It Your Own

This recipe is built around the classic s’more, but the no-churn ice cream base is endlessly adaptable. Swap the marshmallow layer for a no-churn vanilla or strawberry ice cream if you are serving guests who prefer a milder flavor alongside the chocolate. You can also swap the 6-inch pans for 8-inch pans if you want a wider, lower cake that feeds a larger crowd — the layers will simply be thinner and the bake time slightly less.

For a more aesthetic finish on a fancy dessert table, use a kitchen torch to lightly toast the mini marshmallows directly on top of the finished cake just before serving. The golden-edged marshmallows add a dramatic, campfire-inspired visual that stops people in their tracks.

Pro Tips for a Flawless Cake

Always sift the cocoa powder into the powdered sugar before adding it to the whipped cream. Unsifted cocoa clumps stubbornly and creates an unattractive speckled finish on the frosting rather than a smooth, uniform chocolate coat.

If your kitchen is warm, work in short bursts when frosting the cake — 5 to 10 minutes of frosting, then back into the freezer for a few minutes to firm up before continuing. Ice cream cakes melt faster than you expect, and a cold cake is always easier to frost cleanly.

FAQs

Can I use 8-inch cake pans instead of 6-inch pans? Yes. Eight-inch pans will produce a wider, flatter cake rather than the tall, dramatic layers shown in the original. You may need to adjust the freezing time slightly as the layers will be thinner.

How do I get clean slices without ruining the layers? Run a sharp chef’s knife under very hot water, dry it quickly, and cut in one smooth downward motion. Wipe the blade clean between each cut. The hot knife melts through the frozen layers cleanly without dragging or smearing.

Can this cake be made ahead? Absolutely — and it should be. This cake is ideal for making 1 to 2 days in advance. Keep it covered in the freezer until 5 to 10 minutes before serving, then let it soften very slightly at room temperature before slicing.

How long does S’more Ice Cream Cake keep in the freezer? Wrapped tightly, the cake will keep well in the freezer for up to 2 weeks. After that, the texture of the ice cream may begin to deteriorate and the graham cracker layers can lose their crunch.
