3/4 cup graham cracker crumbs: Provides texture and a hint of the classic s’mores flavor.
1 1/2 tbsp granulated sugar (for crumbs): Sweetens the graham cracker crunchies.

Step-by-Step Instructions

Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans to ensure easy release after baking.
In a large mixing bowl, combine the all-purpose flour, granulated sugar, cocoa powder, baking soda, and salt. Mix well to ensure even distribution.
Add the eggs, milk, vegetable oil, and vanilla extract to the bowl. Beat everything together until smooth and well combined.
Stir in the hot water until the mixture is fully combined. The batter will be thin, but this is normal.
Divide the batter evenly between the prepared cake pans and bake for 30-35 minutes or until a toothpick inserted in the center comes out clean.
While the cakes are baking, prepare the graham cracker crunchies. In a small bowl, mix together the graham cracker crumbs, granulated sugar, and melted butter. Spread the mixture on a baking sheet and bake until golden, about 8-10 minutes. Set aside to cool.
For the marshmallow frosting, beat the unsalted butter in a large bowl until creamy. Gradually add the marshmallow fluff, mixing until smooth. Slowly incorporate the powdered sugar until fully blended.
To make the ganache, heat the heavy whipping cream in a small saucepan until just simmering. Pour it over the semi-sweet chocolate chips in a bowl and stir until the mixture is smooth and glossy.
For the vanilla frosting, beat the unsalted butter in a bowl until creamy. Gradually add the powdered sugar, vanilla extract, and milk, mixing until fluffy and smooth.
Once the cakes are completely cooled, assemble the cake by placing one layer on a serving plate. Spread a generous layer of marshmallow frosting on top, followed by a layer of graham cracker crunchies. Drizzle some ganache over this layer, then place the second cake layer on top.
Frost the top and sides of the cake with the remaining marshmallow frosting. Drizzle the ganache on top and decorate with mini marshmallows and additional graham cracker crunchies as desired.

Tips, Storage & Variations

Tips: Make sure all your ingredients are at room temperature before starting for an even batter. This ensures the best texture and rise.
Storage: Store leftover cake slices in an airtight container in the refrigerator for up to 5 days. For optimal freshness, let the cake come to room temperature before serving.
Freezing: You can freeze the assembled cake for up to 3 months. Wrap tightly in plastic wrap and then in aluminum foil to prevent freezer burn. Thaw in the refrigerator overnight before serving.
Flavor Variations: Try swapping the semi-sweet chocolate chips for dark chocolate or even white chocolate for varied flavors. Add a dash of espresso powder to the batter for an enhanced chocolate richness.
