Instructions

Step 1: Make the Chocolate Cake

Preheat oven to 350°F (175°C). Grease and line two 9-inch cake pans.
In a large bowl, whisk together flour, cocoa powder, sugar, baking powder, baking soda, and salt.
Add eggs, milk, vegetable oil, and vanilla extract. Mix until combined.
Stir in hot water (batter will be thin, but that’s okay!).
Divide batter evenly between the cake pans.
Bake for 30–35 minutes, or until a toothpick inserted in the center comes out clean.
Let cakes cool in the pans for 10 minutes, then transfer to a cooling rack.

Step 2: Prepare the Marshmallow Frosting

In a mixing bowl, beat softened butter until creamy.
Add marshmallow fluff, powdered sugar, vanilla extract, and heavy cream. Beat until light and fluffy.

Step 3: Assemble the Cake

Place one cake layer on a serving plate. Spread half of the marshmallow frosting on top.
Sprinkle with crushed graham crackers.
Place the second cake layer on top and spread the remaining frosting over the top and sides.

Step 4: Add the Toppings

Drizzle melted chocolate over the cake.
Sprinkle more graham cracker crumbs and mini marshmallows on top.
For extra gooeyness, toast the marshmallows with a kitchen torch (optional).

Notes

Use hot water in the batter – It enhances the chocolate flavor.
Don’t overmix the batter – This keeps the cake soft.
Let the cakes cool completely before frosting – To prevent melting.
Toast the marshmallows – If you want that authentic campfire feel!
