Ingredients:
- 2 cups (260g) all-purpose flour
- 2 cups (414g) granulated sugar
- 3/4 cup (85g) natural unsweetened cocoa powder
- 2 tsp baking soda
- 1 tsp salt
- 2 large eggs
- 1 cup (240ml) milk
- 1 cup (240ml) vegetable oil
- 1 1/2 tsp vanilla extract
- 1 cup (240ml) hot water
- 3/4 cups (100g) graham cracker crumbs (about 6 full sheet graham crackers)
- 1 1/2 tbsp (20g) granulated sugar
- 1/4 cup (56g) unsalted butter, melted
- 1 3/4 cups (392g) unsalted butter, room temperature (for frosting)
- 3 1/4 cups marshmallow fluff*
Creating the Chocolate Cake Layers
1. Prepare Your Dry Ingredients: In a large mixing bowl, whisk together the flour, granulated sugar, cocoa powder, baking soda, and salt. Make sure everything is well combined. This step ensures that the leavening agents and salt are evenly distributed, leading to a consistent rise and flavor in your cake. Sifting these ingredients can also help prevent lumps and create a lighter texture.
2. Combine Wet Ingredients and Mix the Batter: In a separate bowl, whisk together the eggs, milk, vegetable oil, and vanilla extract. Pour the wet ingredients into the dry ingredients and mix on low speed until just combined. Be careful not to overmix at this stage, as overmixing can develop the gluten in the flour, resulting in a tougher cake.
3. Bloom the Cocoa and Achieve a Moist Batter: Carefully pour the hot water into the batter. The batter will be quite thin at this point, and that’s exactly what we want! The hot water helps to “bloom” the cocoa powder, intensifying its chocolate flavor and contributing to the incredibly moist texture of this cake. Stir gently until the batter is smooth.
4. Bake the Chocolate Layers: Pour the batter evenly into two greased and floured 8-inch round cake pans. Bake at 350°F (175°C) for 30-35 minutes, or until a wooden skewer inserted into the center comes out clean. Let the cakes cool in the pans for 10 minutes before inverting them onto a wire rack to cool completely. It’s crucial that the cakes are fully cooled before frosting to prevent the frosting from melting.
Crafting the Graham Cracker Crust
While your cakes are baking and cooling, let’s get started on the graham cracker crust layer. This is a simple yet essential component that provides that classic s’mores crunch.
1. Combine Crust Ingredients: In a medium bowl, combine the graham cracker crumbs, 1 1/2 tablespoons of granulated sugar, and the melted butter. Stir until the crumbs are evenly moistened.
2. Press into Pans: Divide the crumb mixture evenly between the two cooled cake layers, pressing it gently onto the top of each cake to form an even layer. This will create a delightful textural contrast and a burst of graham cracker flavor with every slice.
Whipping Up the Marshmallow Frosting
This marshmallow frosting is the crowning glory of our S’mores Cake. It’s light, airy, and tastes just like a toasted marshmallow.
1. Cream the Butter: In a large bowl, beat the softened room-temperature butter with an electric mixer until it’s light and fluffy. This process incorporates air into the butter, which is key for a smooth and stable frosting.
2. Add Marshmallow Fluff: Gradually add the marshmallow fluff to the creamed butter, beating on medium speed until thoroughly combined and smooth. Scrape down the sides of the bowl as needed to ensure everything is incorporated. The frosting will be very light and airy. If you prefer a firmer frosting, you can chill it briefly in the refrigerator before frosting.
Assembling Your S’mores Masterpiece
1. Frost the Cake: Place one cake layer, graham cracker side up, onto your serving plate or cake stand. Generously spread about one-third of the marshmallow frosting over the top of the cake, making sure to spread it to the edges. Carefully place the second cake layer on top, graham cracker side up. Then, frost the top and sides of the entire cake with the remaining marshmallow frosting. You can create swirls and peaks with your spatula for a rustic, campfire-inspired look.
2. Optional Garnish: For an extra s’mores touch, you can gently press some additional graham cracker crumbs onto the sides of the frosted cake, or even lightly toast the top of the frosting with a kitchen torch for a truly authentic s’mores experience.
This S’mores Cake is a fantastic dessert for birthdays, holidays, or just a special treat to satisfy your sweet tooth. The combination of rich chocolate cake, crunchy graham cracker, and fluffy marshmallow frosting is simply irresistible. Enjoy!

Frequently Asked Questions:
Can I make this S’mores Cake ahead of time?
Absolutely! You can bake the cake layers a day in advance and store them at room temperature, well-wrapped, or in the refrigerator. The frosting is best made closer to assembly, but you can toast the marshmallows for the topping ahead of time and store them in an airtight container. Assembling the cake on the day you plan to serve it is ideal for the freshest marshmallow frosting.
What if I don’t have a blowtorch for the marshmallows?
No blowtorch, no problem! You can achieve a beautifully toasted marshmallow effect by placing the frosted cake under your oven’s broiler for a minute or two, watching it very carefully to prevent burning. Alternatively, you can toast marshmallows separately in a pan or under the broiler and then arrange them on top of the frosted cake.
Are there any gluten-free options for this S’mores Cake?
Yes, you can definitely adapt this recipe for a gluten-free version! Simply substitute a good quality gluten-free all-purpose flour blend for the regular flour in the cake recipe. You’ll want to ensure your graham cracker crumbs are also gluten-free. The marshmallow and chocolate components are typically gluten-free, but it’s always good to check your labels.
