Preparation
- Preheat your oven to 350°F. Grease and flour two 9-inch round cake pans. In a large mixing bowl, cream the butter and sugar until light and fluffy. Add eggs one at a time, beating well after each addition. Stir in vanilla. In another bowl, whisk together flour, baking powder, baking soda, and salt. Gradually add to the creamed mixture alternately with milk, beating well after each addition. Divide the batter between the prepared pans.

- For the custard, heat milk in a saucepan over medium heat until hot but not boiling. In a bowl, whisk sugar, cornstarch, and egg yolks until smooth. Gradually whisk the hot milk into the egg mixture. Return to the saucepan and cook over medium heat, stirring constantly, until thickened. Stir in vanilla, then cool completely.

- Place one cake layer on a serving plate. Spread the custard evenly over the top. Place the second cake layer on top. Pour the ganache over the cake, spreading it to the edges and allowing it to drip down the sides.

Notes
FAQ
Can I make the cake layers in advance?
Yes, you can bake the cake layers up to two days in advance. Once baked, allow them to cool completely and then wrap them tightly in plastic wrap. Store at room temperature or in the refrigerator until you’re ready to assemble the cake. This can help save time on the day of serving and allows the flavors to develop.
What is the best way to achieve a smooth ganache?
To achieve a smooth ganache, ensure that both the cream and chocolate are of high quality. Heat the cream until it just begins to simmer, then pour it over the chopped chocolate. Let it sit undisturbed for a few minutes before stirring gently. Avoid over-stirring to prevent air bubbles, and allow the ganache to cool slightly before using it for a glossy finish.
How can I prevent the custard from becoming lumpy?
To prevent lumps in your custard, make sure to whisk the sugar, cornstarch, and egg yolks until smooth before adding the hot milk. Gradually combine the hot milk into the egg mixture while whisking constantly. Return the mixture to the saucepan and stir continuously over medium heat until it thickens. Strain the custard through a fine sieve if needed to remove any small lumps.
