Cake Preparation

  1. 1

    Preheat the Oven

    Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.

    Mix Dry Ingredients

    In a large bowl, combine flour, sugar, cocoa powder, baking powder, baking soda, and salt. Whisk together until well mixed.

    Add Wet Ingredients

    Add eggs, milk, oil, and vanilla extract to the dry ingredients. Mix until smooth.

  4. 4

    Add Boiling Water

    Carefully stir in the boiling water until well combined (the batter will be thin).

  5. 5

    Bake the Cake

    Pour the batter evenly into the prepared pans and bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean.

    Cool the Cake

    Once baked, remove from the oven and let the cakes cool in the pans for 10 minutes before transferring to a wire rack to cool completely.

    Whip the Cream

    In a mixing bowl, combine heavy cream, powdered sugar, and vanilla extract. Whip until soft peaks form.
