Recipe Information
Ingredients
- 2.5 cups all-purpose flour
- 0.75 cup unsweetened cocoa powder
- 2 cups granulated sugar
- 0.5 cup brown sugar
- 1.5 teaspoons baking powder
- 1.5 teaspoons baking soda
- 1 teaspoon salt
- 3 eggs
- 1.25 cups whole milk
- 0.5 cup vegetable oil
- 2 teaspoons pure vanilla extract
- 1 cup boiling water
- 1.5 cups white chocolate chips
- 2 cups heavy cream (for mousse)
- 0.5 cup powdered sugar (for mousse)
- 1 cup unsalted butter (for frosting)
- 1.5 cups semi-sweet chocolate chips (for frosting)
- 0.5 cup heavy cream (for frosting)
Instructions
Preheat the oven to 350°F (175°C) and grease and flour three 8-inch round cake pans.
In a large bowl, sift together the flour, cocoa powder, granulated sugar, brown sugar, baking powder, baking soda, and salt.
In a separate bowl, whisk together the eggs, milk, vegetable oil, and vanilla extract until smooth.
Gradually add the wet ingredients to the dry ingredients and mix until well combined.
Slowly stir in the boiling water (the batter will be thin).
Divide the batter evenly among the prepared pans and bake for 30-35 minutes or until a toothpick inserted into the center comes out clean.
Cool the cakes in the pans for 10 minutes, then transfer them to a wire rack to cool completely.
To make the white chocolate mousse, melt the white chocolate chips in a heatproof bowl over a saucepan of simmering water (double boiler method), stirring until smooth. Let it cool slightly.
In a separate bowl, whip the heavy cream with powdered sugar until stiff peaks form.
Gently fold the melted white chocolate into the whipped cream until fully incorporated. Chill in the refrigerator for 30 minutes.
For the frosting, melt the semi-sweet chocolate chips with the heavy cream using the double boiler method, stirring until smooth.
Let the frosting cool to room temperature, then beat in the softened butter until creamy and spreadable.
To assemble the cake, place one cake layer on a serving plate and spread a generous layer of white chocolate mousse on top.
Repeat with the second cake layer and another layer of mousse. Top with the final cake layer.
Frost the outside of the cake with the chocolate frosting, smoothing it evenly over the top and sides.
Chill the assembled cake for at least 1 hour before serving to set the mousse and frosting.
