No Bake S’mores Cake Recipe

This No Bake S’mores Cake is pure nostalgia in every chilled, chocolaty, marshmallowy bite—a fire-free twist on the childhood campfire classic! With layers of graham crackers, fluffy homemade marshmallow meringue, and silky ganache, this dreamy dessert is made entirely without an oven and is guaranteed to wow guests at any gathering (or justify a Tuesday night treat).

Ingredients You’ll Need

Every magical bite of No Bake S’mores Cake starts with a handful of pantry staples, lovingly transformed into that soul-satisfying campfire flavor. Here’s what goes into each luscious layer—and why every ingredient matters.

• Finely Chopped Chocolate (semi-sweet or milk): The base of your chocolate ganache—choose a flavor you adore for a cake that tastes just right for you!
• Heavy Cream: This turns the chocolate into a silky, smooth ganache that seems to melt right into every graham cracker layer.
• Room-Temperature Egg Whites: The backbone of your homemade marshmallow meringue—bring them to room temp for a fluffier, billowy finish.
• Granulated Sugar: Sweetens the meringue and helps it whip up glossy and stable.
• Cream of Tartar: Don’t skip this tiny but mighty ingredient—it keeps your meringue standing tall and beautiful.
• Pure Vanilla Extract: Adds that irreplaceable toasted-marshmallow warmth to every bite.
• Graham Crackers: The classic s’mores crunch—layered generously throughout to deliver that familiar flavor and structure.

Variations

This No Bake S’mores Cake recipe is made for improvising—don’t let a missing ingredient or new craving stand in the way. Here are some of my favorite playful twists and simple swaps:

• Peanut Butter S’mores Cake: Add a generous swipe of peanut butter between the graham cracker and ganache layers for a sweet-salty surprise.
• Nut-Free Version: Use allergy-friendly chocolate and marshmallow fluff (instead of homemade meringue) to keep it nut-free and extra easy.
• Dark Chocolate Dream: Swap in bittersweet chocolate for a deeper, more grown-up flavor profile that s’mores lovers will swoon over.
• Gluten-Free Makeover: Grab gluten-free graham crackers or digestive biscuits for an allergy-friendly treat everyone can savor.

How to Make No Bake S’mores Cake

Step 1: Prep the Pan

Begin by lining an 8- or 9-inch square baking pan with parchment paper, leaving an overhang on the sides. This little trick is your best friend—it’ll let you lift the whole No Bake S’mores Cake out in one lovely piece for easy slicing and gorgeous presentation.

Step 2: Make the Ganache

Place your chopped chocolate in a bowl, then gently heat the cream in a saucepan until it just starts to simmer. Pour it over the chocolate and let the mixture sit for a few minutes to melt. Stir, and watch the magic happen as it turns glossy and smooth. Pop this in the fridge while you whip up your meringue.

Step 3: Fluffy Marshmallow Meringue

Set a heatproof bowl over a pan of simmering water (or use a double boiler) and whisk your egg whites, sugar, and cream of tartar together. Keep whisking—a good arm workout—for about four minutes, until everything dissolves and thins out. Off the heat, add vanilla, then beat with a mixer until stiff, glossy peaks form. Scoop out one heaping cup for your topping and stash it in the fridge until the big reveal at the end.

Step 4: Assemble those Iconic Layers

Start with a whisper-thin layer of meringue at the bottom (this helps your first graham cracker layer stay put), then alternate: graham crackers, marshmallow meringue, graham crackers, gooey ganache, repeat! Build 6 layers high, finishing with chocolate ganache on top. If it looks a little messy, you’re doing it exactly right—this cake is all heart and happiness.

Step 5: Chill—Let the Magic Happen

Cover your masterpiece tightly and refrigerate for at least 12 hours—overnight is perfect. This long chill lets the layers meld, the graham crackers soften just right, and all the flavors become impossibly delicious together.

Step 6: Top and Torch (The Grand Finale!)

Liberate your chilled No Bake S’mores Cake from the pan and parchment, and transfer to a pretty, heat-proof serving board. Spread the reserved marshmallow meringue on top with bold swoops or gentle peaks. Get dramatic: toast it with a kitchen torch for that golden s’mores flair, or simply slice and serve right away—either way, every forkful is magical.

How to Serve No Bake S’mores Cake

Garnishes

For an extra bit of s’mores whimsy, try topping your No Bake S’mores Cake with mini chocolate chips, toasted mini marshmallows, or an artful sprinkle of crushed graham crackers. A drizzle of chocolate sauce and a few swirls with a spoon will make it look absolutely irresistible—little ones will love adding their own creative flair!

Side Dishes

This cake is a star all on its own, but if you want to go all out, serve alongside fresh strawberries or a big pitcher of ice-cold milk or cold brew. For a summer cookout, a scoop of vanilla or coffee ice cream on the side is pure bliss with every chilled bite.

Creative Ways to Present

You can cut the cake into generous squares for a rustic feel or slice it into tiny, elegant bars for a party platter. For another playful idea, layer the ingredients in clear jars or parfait glasses—perfect for portable picnic desserts or kid-friendly treats at birthday celebrations. No matter how you serve it, expect instant smiles!

Make Ahead and Storage

Storing Leftovers

Keep any leftover No Bake S’mores Cake covered and refrigerated. The layers will hold their shape beautifully for up to two days—but fair warning, the marshmallow topping may start to soften. It’ll still taste wonderful, even if a little less poufy!

Freezing

You can freeze No Bake S’mores Cake, but it’s best to do so before adding the meringue topping. Wrap tightly and freeze for up to one month. Thaw in the fridge overnight, then whip up a fresh batch of marshmallow meringue for the crowning finish before serving.

Reheating

There’s no need for reheating—this cake is designed to be enjoyed cold, straight from the fridge or after a brief rest at room temperature. If you’re after that just-toasted marshmallow effect, a quick pass under a kitchen torch does the trick!
