Directions
Make the chocolate cake: Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans. In a large bowl, combine flour, sugar, cocoa powder, baking soda, and salt. Add eggs, milk, vegetable oil, and vanilla. Mix until smooth. Gradually stir in hot water. Pour the batter into the prepared pans. Bake for 30-35 minutes or until a toothpick comes out clean. Let the cakes cool completely.

Make the toasted marshmallow frosting: In a large bowl, beat 1 3/4 cups unsalted butter until creamy. Gradually add marshmallow fluff and mix until combined. Slowly add in powdered sugar until the frosting is smooth.
Make the chocolate ganache: In a saucepan, heat heavy cream until it just begins to simmer. Remove from heat and add chocolate chips. Stir until smooth. Let cool slightly.
Make the vanilla frosting: In another bowl, beat 3/4 cup unsalted butter until creamy. Gradually add powdered sugar, vanilla extract, and milk. Mix until smooth.
