Ingredients Method Notes

Ingredients
  

  • 1 ¾ cups all-purpose flour
  • 1 ¾ cups granulated sugar
  • ¾ cup unsweetened cocoa powder
  • 1 ½ teaspoons baking powder
  • 1 ½ teaspoons baking soda
  • 1 teaspoon salt
  • 2 large eggs
  • 1 cup whole milk
  • ½ cup vegetable oil
  • 2 teaspoons vanilla extract
  • 1 cup boiling water
  • 1 cup graham cracker crumbs
  • 1 cup mini marshmallows
  • 1 cup marshmallow fluff
  • 1 cup heavy whipping cream
  • ½ cup powdered sugar
  • Chocolate shavings or crushed graham crackers for garnish optional

Method
 

  1. Preheat Oven: Preheat your oven to 350°F (175°C) and grease and flour two 9-inch round cake pans.
  2. Make Cake Batter: In a large bowl, mix flour, sugar, cocoa powder, baking powder, baking soda, and salt. Add eggs, milk, vegetable oil, and vanilla extract and beat for 2 minutes. Stir in boiling water; the batter will be thin.
  3. Bake: Pour batter evenly into prepared pans. Bake for 30-35 minutes, or until a toothpick inserted comes out clean. Cool in pans for 10 minutes, then transfer to wire racks to cool completely.
  4. Make Marshmallow Filling: Whip heavy cream until soft peaks form. Fold in marshmallow fluff and mini marshmallows.
  5. Assemble Cake: Once cakes are cool, spread marshmallow filling between the two layers.
  6. Make Frosting: Whip heavy cream and powdered sugar until stiff peaks form. Spread frosting on the top and sides of the cake.
  7. Garnish: Top with chocolate shavings or crushed graham crackers. Slice and serve.

Notes

Top with chocolate shavings or crushed graham crackers for added flavor and crunch. The marshmallow fluff gives the filling its signature flavor, but you can also use marshmallow cream for a similar effect. This cake can be made in advance and stored in the fridge for up to 2 days for maximum freshness.
