Ingredients:
- 65 grams (1/2 cup or 4-5 sheets) graham cracker crumbs
- 240 grams (2 cups) all-purpose flour (spooned and leveled)
- 10 grams (1 Tbsp) baking powder
- 1/2 tsp fine sea salt
- 1/4 tsp cinnamon (optional)
- 56 grams (1/4 cup) unsalted butter (room temperature)
- 120 mL (1/2 cup) canola oil
- 100 grams (1/2 cup) granulated sugar
- 200 grams (1 cup) light brown sugar (lightly packed)
- 1/2 Tbsp vanilla extract
- 3 large eggs (room temperature)
- 240 mL (1 cup) buttermilk (room temperature)
- 113 grams (1/2 cup/4 oz) dark chocolate chips
- 120 mL (1/2 cup/4 oz) heavy cream
- 6 (200g) large egg whites (room temperature)
Instructions:
1. Preparing the Graham Cracker Crumbs and Cake Batter
First, let’s get our graham cracker crumbs ready. You can achieve this by finely crushing graham crackers in a food processor or by placing them in a sealed bag and crushing them with a rolling pin. Measure out 65 grams for our delicious cake layers.
Now, preheat your oven to 175°C (350°F) and grease and flour two 8-inch round cake pans. You can also line the bottoms with parchment paper for extra insurance against sticking. In a medium bowl, whisk together the all-purpose flour, baking powder, fine sea salt, and the optional cinnamon. This dry ingredient mixture will form the base of our cake. In a large bowl, cream together the softened unsalted butter, canola oil, granulated sugar, and light brown sugar until light and fluffy. This combination of butter and oil will give us a cake that is both rich and incredibly moist. Beat in the vanilla extract.
Next, add the eggs one at a time, beating well after each addition to ensure they are fully incorporated. Gradually add the dry ingredients to the wet ingredients, alternating with the buttermilk, beginning and ending with the dry ingredients. Mix until just combined; be careful not to overmix, as this can lead to a tough cake. Divide the batter evenly between the prepared cake pans.
2. Baking the Cake Layers and Making the Chocolate Ganache
Place the cake pans in the preheated oven and bake for approximately 30-35 minutes, or until a wooden skewer inserted into the center of the cakes comes out clean. Once baked, let the cakes cool in their pans for about 10-15 minutes before inverting them onto a wire rack to cool completely. It’s crucial that the cakes are entirely cool before frosting.
While the cakes are cooling, let’s prepare the luscious dark chocolate ganache. Place the dark chocolate chips in a heatproof bowl. In a small saucepan, heat the heavy cream over medium heat until it just begins to simmer around the edges. Do not let it boil. Pour the hot cream over the chocolate chips and let it sit for 5 minutes without stirring. This allows the heat from the cream to gently melt the chocolate. After 5 minutes, gently whisk the mixture until it is smooth and glossy. Set aside to cool to room temperature, which will thicken it to a spreadable consistency.
3. Crafting the Toasted Marshmallow Meringue Frosting
This is where the magic truly happens! In a clean, dry bowl of a stand mixer (or using a hand mixer), combine the 6 large egg whites with the granulated sugar (reserved from the ganache making, or if you want a firmer meringue, use an additional 100g granulated sugar). Place the bowl over a saucepan of simmering water (creating a double boiler), ensuring the bottom of the bowl doesn’t touch the water. Whisk constantly until the sugar is completely dissolved and the mixture is warm to the touch, about 160°F (71°C) if using a thermometer. This step is essential for dissolving the sugar and pasteurizing the egg whites.
Remove the bowl from the heat and, using the whisk attachment of your stand mixer, beat the egg whites on high speed until stiff, glossy peaks form. This process can take 8-10 minutes. The meringue should be thick and hold its shape when the whisk is lifted. Once the meringue is formed, you will gently fold in the graham cracker crumbs. Be delicate with this step to maintain the airy texture of the meringue.
4. Assembling the S’mores Masterpiece
Once all components are cooled and ready, it’s time to assemble! Place one of the cooled cake layers on your serving platter or cake stand. Spread a generous layer of the chocolate ganache over the top of this first cake layer, ensuring an even coating. Carefully place the second cake layer on top of the ganache.
Now, it’s time to frost your magnificent S’mores Layer Cake. Using an offset spatula, generously apply the toasted marshmallow meringue frosting all over the top and sides of the cake, creating swirls and peaks reminiscent of fluffy marshmallows. You can be as artistic as you like here!
5. Achieving the Perfect Toasted Finish
For that authentic s’mores experience, we need to toast the meringue. You can do this in one of two ways. The easiest method is to use a kitchen torch to carefully toast the peaks and swirls of the meringue until they are golden brown and beautifully caramelized. Move the torch continuously to avoid burning any one spot. Alternatively, you can place the cake under a preheated broiler for a very short period (watch it extremely closely, as it can burn quickly!) until the meringue is toasted to your liking.
Allow the cake to sit at room temperature for about 30 minutes before slicing and serving. This allows the frosting to set slightly. When you slice into this S’mores Layer Cake, you’ll reveal the beautiful layers of chocolate and cake, topped with that irresistible toasted marshmallow meringue. Enjoy every decadent bite!

Conclusion:
And there you have it – your very own S’mores Layer Cake! This recipe is an absolute triumph because it captures all the nostalgic, gooey, chocolatey, and marshmallowy goodness of campfire s’mores in a stunning, shareable dessert. It’s not just a cake; it’s an experience that will transport you back to starry nights and crackling fires.

I highly recommend serving this S’mores Layer Cake slightly warm to let the frosting truly shine and the chocolate ganache become extra luscious. It’s perfect for birthdays, holiday gatherings, or simply as a show-stopping treat to impress friends and family. For variations, feel free to add a sprinkle of graham cracker crumbs between the layers for an extra textural crunch, or even incorporate mini chocolate chips into the cake batter for an intensified chocolate flavor. Don’t be afraid to get creative! I truly encourage you to give this S’mores Layer Cake a try; you won’t regret it!
Frequently Asked Questions:
Can I toast the marshmallow frosting with a kitchen torch?
Absolutely! Using a kitchen torch is a fantastic way to achieve that perfectly toasted, slightly caramelized marshmallow flavor and appearance. Just be sure to toast it evenly in small sections for the best results.
What’s the best way to store leftover S’mores Layer Cake?
Store any leftover S’mores Layer Cake in an airtight container at room temperature for up to 2 days. If you need to store it longer, refrigeration is recommended, but let it come to room temperature for about 30 minutes before serving to enjoy its full texture and flavor.
