Step-by-Step Guide to Making S’mores Cake
Step 1: Bake the Cake Layers
- Preheat your oven to 350°F (175°C) and grease and flour three cake pans.
- In a mixing bowl, combine graham cracker crumbs, flour, sugar, butter, eggs, milk, and leavening agents.
- Mix until smooth, then divide the batter evenly among the prepared pans.
- Bake for 20-25 minutes, or until a toothpick inserted into the center of the cake comes out clean. Let the cakes cool completely.
Step 2: Make the Chocolate Ganache
- Heat heavy cream in a saucepan until it just begins to simmer.
- Pour the hot cream over chopped chocolate and let it sit for a few minutes.
- Stir until smooth and glossy, then let it cool to a spreadable consistency.
Step 3: Prepare the Marshmallow Frosting
- In a heatproof bowl, combine egg whites and sugar, whisking until well blended.
- Place the bowl over a pot of simmering water and whisk constantly until the sugar dissolves and the mixture is warm.
- Remove from heat and beat with a mixer until stiff peaks form. Add vanilla extract and mix until combined.
Step 4: Assemble the Cake
- Place one cake layer on a serving plate and spread a layer of chocolate ganache on top.
- Add the second cake layer and repeat with another layer of ganache.
- Top with the third cake layer and cover the entire cake with marshmallow frosting.
Step 5: Toast the Frosting
- Use a kitchen torch to lightly toast the marshmallow frosting, creating a golden, campfire-inspired finish.
- Garnish with graham cracker crumbs, chocolate shavings, or mini marshmallows, if desired.
Tips for Perfect S’mores Cake
- Use Room Temperature Ingredients: This helps achieve a smooth, evenly mixed batter.
- Don’t Overmix the Batter: Overmixing may result in a dense, heavy cake.
- Chill the Ganache: Let the ganache cool slightly before spreading to avoid it dripping down the sides.
- Toast Carefully: Use a kitchen torch in short bursts to avoid burning the marshmallow frosting.

This cake is a show-stopper on its own, but here are a few ideas to make it even more special:

- At a Summer Party: Pair with other campfire-inspired desserts like grilled fruit or chocolate-dipped strawberries.
- As a Birthday Cake: Decorate with candles and sparklers for a festive touch.
