Cream Filling
Prepare the Cream:
In a saucepan, whisk together the egg yolks and 1/4 cup sugar until well combined.
Add the vanilla essence, milk, and cornstarch, and stir until smooth.
Cook over medium heat, stirring constantly, until the mixture thickens.
Cover the cream with plastic wrap, ensuring the wrap touches the surface to prevent a skin from forming. Set aside to cool to room temperature.
