Method

Cake Base

  1. 1

    Prepare the Oven and Pan

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

  2. 2

    Combine Dry Ingredients

    In a large bowl, sift together the all-purpose flour, granulated sugar, cocoa powder, baking powder, baking soda, and salt.

  3. 3

    Add Wet Ingredients

    Add the eggs, milk, vegetable oil, and vanilla extract to the dry ingredients. Mix until just combined.

  4. 4

    Incorporate Boiling Water

    Carefully stir in the boiling water until the batter is smooth. It will be thin.

  5. 5

    Bake the Cake

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

  6. 6

    Cool the Cakes

    Remove from the oven and let the cakes cool in the pans for 10 minutes before transferring them to a wire rack to cool completely.

White Chocolate Mousse

  1. 7

    Melt the White Chocolate

    Chop the white chocolate into small pieces and melt it in a heatproof bowl over simmering water or in the microwave in 20-second increments until smooth. Let it cool slightly.

  2. 8

    Prepare the Gelatin

    In a small bowl, combine the gelatin and cold water. Let it sit for about 5 minutes until it blooms.

  3. 9

    Whip the Heavy Cream

    In a separate bowl, whip the heavy cream and powdered sugar until stiff peaks form. Add the vanilla extract and mix gently.

  4. 10

    Combine the Mixtures

    Gently fold the melted white chocolate into the whipped cream mixture until fully combined. Then, fold in the bloomed gelatin until incorporated.

  5. 11

    Chill the Mousse

    Cover the bowl with plastic wrap and refrigerate for at least 2 hours until set.

Ganache Topping

  1. 12

    Heat the Heavy Cream

    In a small saucepan over medium heat, bring the heavy cream to a simmer.

  2. 13

    Melt the White Chocolate

    Remove the saucepan from the heat and add the chopped white chocolate. Stir until completely melted and smooth.

  3. 14

    Cool the Ganache

    Let the ganache cool slightly at room temperature before using it on the cake.

Assembling the Cake

  1. 15

    Layer the Cake

    Once the cakes are completely cool, place one layer on a serving plate. Spread half of the white chocolate mousse on top.

  2. 16

    Add Second Layer

    Place the second layer on top of the mousse and spread the remaining mousse on top.

  3. 17

    Pour Ganache Over Cake

    Finally, pour the cooled ganache over the top of the cake, allowing it to drip down the sides.

  4. 18

    Chill and Serve

    Refrigerate the assembled cake for at least 30 minutes before slicing and serving.
