- 2 cups granulated sugar: Adds sweetness and helps create a tender cake.
- 3/4 cup natural unsweetened cocoa powder: Delivers rich chocolate flavor.
- 2 tsp baking soda: Acts as a leavening agent, helping the cake rise.

- 1 cup vegetable oil: Adds moisture and keeps the cake soft.

- 1 cup hot water: Deepens the chocolate flavor and ensures a moist cake.
- 3/4 cup graham cracker crumbs: Adds a crunchy texture that mimics traditional s’mores.
- 1 1/2 tbsp granulated sugar (for crumbs): Sweetens the graham cracker mixture.
- 1/4 cup unsalted butter, melted: Binds the graham cracker mixture together.
- 1 3/4 cups unsalted butter (for frosting): Creates a rich and creamy texture.
- 3 1/4 cups marshmallow fluff: Forms the base of the fluffy marshmallow frosting.
- 6 cups powdered sugar (for frosting): Sweetens the frosting and adds structure.
- 1 1/2 cups mini marshmallows: Provides that classic s’mores experience in the cake.
- 9 oz semi-sweet chocolate chips: Essential for the rich chocolate ganache.
- 3/4 cup heavy whipping cream (for ganache): Creates a silky smooth chocolate ganache.
- 3/4 cup unsalted butter (for vanilla frosting): Adds creaminess to the vanilla frosting.
- 3 cups powdered sugar (for vanilla frosting): Sweetens and thickens the vanilla frosting.
- 1 tsp vanilla extract (for vanilla frosting): Adds flavor depth to the vanilla frosting.

Step-by-Step Instructions
- Preheat your oven to 350°F (175°C) and grease and flour two 9-inch round cake pans.
- In a large mixing bowl, combine the all-purpose flour, granulated sugar, cocoa powder, baking soda, and salt. Mix thoroughly.
- Add the eggs, milk, vegetable oil, and vanilla extract to the dry ingredients. Beat on medium speed for about 2 minutes until well combined.
- Stir in the hot water carefully. Note that the batter will be thin.
- Divide the batter evenly between the prepared pans. Bake for 30-35 minutes or until a toothpick inserted into the center comes out clean. Cool completely in the pans.
- For the graham cracker crunch, mix together the graham cracker crumbs, 1 1/2 tablespoons of granulated sugar, and melted butter. Spread the mixture onto a baking sheet and bake at 350°F for 10-12 minutes. Let it cool completely before using.
- For the toasted marshmallow frosting, beat the unsalted butter until creamy. Mix in the marshmallow fluff and gradually add powdered sugar until smooth. If needed, adjust the consistency with a little milk.
- For the chocolate ganache, heat the heavy cream in a saucepan until simmering, then pour it over the chocolate chips. Let it sit for 5 minutes, then stir until smooth.
- For the vanilla frosting, beat the unsalted butter until smooth. Gradually mix in the powdered sugar, vanilla extract, and milk, whipping until fluffy.
- To assemble the cake, place one layer on a serving plate. Spread a generous layer of marshmallow frosting, sprinkle with graham cracker crunch, and add mini marshmallows. Top with the second layer.
- Pour the ganache over the cake, allowing it to drip down the sides. Use the vanilla frosting to pipe along the edges and top of the cake, finishing with a sprinkle of more mini marshmallows and graham cracker crunch.
