🍳 Instructions

1. Bake the Chocolate Cake:

• Preheat oven to 350°F (175°C). Grease and line cake pans with parchment paper.
• In a large bowl, whisk together flour, cocoa powder, sugar, baking powder, baking soda, and salt.
• Add eggs, milk, oil, and vanilla. Beat until smooth.
• Gradually stir in boiling water (batter will be thin — that’s good!).
• Divide between pans and bake 30–35 minutes, or until a toothpick inserted comes out clean. Cool completely.

2. Make the Ganache:

• Heat cream in a saucepan until just simmering. Pour over chopped chocolate and let sit 2 minutes. Stir until silky smooth. Set aside to thicken slightly.

3. Make the Marshmallow Frosting:

• In a heatproof bowl, combine egg whites, sugar, and cream of tartar.
• Set over simmering water (double boiler method) and whisk constantly until sugar is dissolved and mixture is warm (about 160°F if using a thermometer).
• Transfer to mixer and whip on high speed until stiff, glossy peaks form. Beat in vanilla.

4. Assemble the Cake:

• Place one cake layer on a serving plate. Spread a layer of ganache, sprinkle graham cracker crumbs, and add a thick layer of marshmallow frosting.
• Repeat with the second cake layer. Frost the outside with marshmallow frosting.
• Press extra graham crackers onto the sides and top.
• Optional: Torch the frosting lightly for that true s’mores campfire vibe!

❓ Frequently Asked Questions

Can I use store-bought marshmallow fluff instead?
Yes! It’s faster, but homemade frosting tastes more authentic and toasts better.

Do I need a kitchen torch?
Not required, but it adds that irresistible roasted marshmallow flavor and look!

Can I make this ahead?
Yes — bake the cake layers a day ahead, then assemble and frost the day you serve for freshest results.
