Instructions:
1. Preheat the Oven:
Preheat your oven to 350°F (175°C). Grease and line a 9-inch (23 cm) round cake pan with parchment paper.
2. Prepare the Cake Batter:
- In a large mixing bowl, beat the 6 eggs and 1 tbsp of sugar together using an electric mixer on high speed until pale and fluffy.
- Sift together the self-raising flour, all-purpose flour, and cocoa powder. Gradually fold these dry ingredients into the egg mixture until well combined.
- Add the 2 tbsp of vanilla extract and gently fold it into the batter until incorporated.
3. Bake the Cake:
Pour the batter into the prepared cake pan and smooth the top.
Bake in the preheated oven for 30-35 minutes, or until a toothpick inserted into the center comes out clean.
Allow the cake to cool in the pan for about 10 minutes, then transfer it to a wire rack to cool completely.
4. Prepare the Custard:
- In a small bowl, mix the corn flour with a little bit of the milk to form a smooth slurry.
- In a medium saucepan, heat the remaining milk over medium heat until it begins to simmer.
- Stir in the corn flour slurry and cook, stirring constantly, until the mixture thickens.
- Remove from heat and stir in the white chocolate and 1 tsp of vanilla extract until the chocolate is fully melted and incorporated.
- Let the custard cool to room temperature.
5. Assemble the Cake:
- Once the cake is completely cooled, slice it horizontally to create two even layers.
- Spread the white chocolate custard evenly over the bottom layer, then place the top layer on top of the custard.
6. Prepare the Ganache:
- In a heatproof bowl, combine the dark chocolate and heavy whipping cream.
- Place the bowl over a saucepan of simmering water (double boiler method) and stir until the chocolate is completely melted and smooth.
- Allow the ganache to cool slightly, then pour it over the top of the cake, spreading it evenly over the top and allowing it to drape down the sides.
7. Chill and Serve:
- Refrigerate the cake for at least 1 hour to allow the custard and ganache to set.
- Slice and serve chilled.
