S’mores Cake Recipe
Ingredients
For the Cake:
- 1 1/2 cups graham cracker crumbs about 15 graham crackers
- 1 1/2 cups all-purpose flour
- 1 tablespoon baking powder
- 1/2 teaspoon salt
- 1 cup unsalted butter room temperature
- 1 1/2 cups granulated sugar
- 3 large eggs
- 2 teaspoons vanilla extract
- 1 cup whole milk
For the Chocolate Ganache Filling:
- 1 cup heavy cream
- 8 ounces semisweet chocolate finely chopped
For the Marshmallow Frosting:
- 4 large egg whites
- 1 cup granulated sugar
- 1/4 teaspoon cream of tartar
- 1 teaspoon vanilla extract
For Decoration:
- Mini marshmallows
- Graham cracker crumbs
- Chocolate shavings or chunks
Instructions
Prepare the Cake:
- Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
- In a medium bowl, whisk together the graham cracker crumbs, flour, baking powder, and salt. Set aside.
- In a large bowl, beat the butter and sugar together with an electric mixer until light and fluffy.
- Add the eggs one at a time, beating well after each addition. Mix in the vanilla extract.
- Alternately add the dry ingredients and the milk to the butter mixture, beginning and ending with the dry ingredients. Mix until just combined.
- Divide the batter evenly between the prepared cake pans and smooth the tops.
- Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean.
- Let the cakes cool in the pans for 10 minutes, then turn them out onto a wire rack to cool completely.
Make the Chocolate Ganache Filling:
- Heat the heavy cream in a small saucepan over medium heat until it just begins to simmer.
- Pour the hot cream over the chopped chocolate in a heatproof bowl. Let sit for 5 minutes, then stir until smooth.
- Allow the ganache to cool and thicken slightly before using.
Make the Marshmallow Frosting:
- In a heatproof bowl, combine the egg whites, sugar, and cream of tartar. Place the bowl over a pot of simmering water, ensuring the bottom of the bowl does not touch the water.
- Whisk constantly until the sugar has dissolved and the mixture reaches 160°F (71°C) on a candy thermometer.
- Remove from heat and beat with an electric mixer on high speed until stiff, glossy peaks form, about 5-7 minutes. Beat in the vanilla extract.
Assemble the Cake:
- Place one cake layer on a serving plate. Spread a thick layer of chocolate ganache over the top.
- Place the second cake layer on top.
- Frost the entire cake with the marshmallow frosting, creating swirls and peaks for a rustic look.
- Use a kitchen torch to lightly toast the frosting for a s’mores effect.
Decorate:
- Garnish the cake with mini marshmallows, graham cracker crumbs, and chocolate shavings or chunks.
Notes
- Room Temperature Ingredients: Make sure your butter, eggs, and milk are at room temperature before mixing. This ensures a smoother batter and more even baking.
- Ganache Consistency: If your ganache is too thin to spread, let it sit at room temperature or refrigerate it for a few minutes until it thickens. Stir occasionally to maintain a smooth consistency.
- Marshmallow Frosting: Whip the frosting until stiff peaks form. This will help the frosting hold its shape and make it easier to toast.
- Torching the Frosting: Use a kitchen torch to lightly toast the marshmallow frosting. If you don’t have a torch, you can briefly place the cake under a broiler, but watch it carefully to prevent burning.
- Cake Layers: Ensure the cake layers are completely cooled before assembling to prevent the ganache and frosting from melting.
- Storage: Store any leftover cake in an airtight container at room temperature for up to 2 days. For longer storage, refrigerate it, but bring it to room temperature before serving for the best flavor and texture.
- Making Ahead: You can bake the cake layers a day in advance. Wrap them tightly in plastic wrap and store at room temperature. Assemble and frost the cake on the day of serving.
- Variation: Add a sprinkle of sea salt on the ganache layer for a sweet and salty twist.
