Description

A rich, moist chocolate cake inspired by cozy mugs of hot cocoa, topped with fluffy, glossy marshmallow frosting for the ultimate winter dessert experience.


Ingredients

Scale
  • 2 cups all-purpose flour
  • 2 cups granulated sugar
  • 3/4 cup unsweetened cocoa powder
  • 2 tsp baking powder
  • 1 1/2 tsp baking soda
  • 1 tsp salt
  • 2 large eggs
  • 1 cup milk
  • 1/2 cup vegetable oil
  • 2 tsp vanilla extract
  • 1 cup boiling water
  • 1/2 cup mini marshmallows (for topping)
  • 1 jar marshmallow fluff or 2 cups homemade marshmallow frosting


Instructions

  1. Preheat oven to 350°F (175°C). Grease and line two 8-inch round cake pans with parchment paper.
  2. In a bowl, whisk together flour, cocoa powder, sugar, baking powder, baking soda, and salt.
  3. In another bowl, whisk eggs, milk, oil, and vanilla until smooth. Add dry ingredients gradually, then stir in boiling water until the batter is smooth and thin.
  4. Pour batter evenly into the prepared pans and bake for 30–35 minutes or until a toothpick inserted comes out clean.
  5. Cool cakes in pans for 10 minutes, then transfer to wire racks to cool completely.
  6. To make the frosting, beat marshmallow fluff (or homemade frosting) until light and fluffy.
  7. Frost one cake layer, stack the second on top, and cover the entire cake with marshmallow frosting.
  8. Optional: Lightly toast the frosting with a kitchen torch and decorate with mini marshmallows or chocolate shavings.

Notes

  • Do not overbake to keep the cake moist and tender.
  • Use boiling water or hot coffee to intensify chocolate flavor.
  • Cool completely before frosting to prevent melting.
  • Store frosted cake covered at room temperature for up to 2 days or in the fridge for 5 days.
