# How To Make It:

04 - Pour half of the custard mixture over the bread cubes, pressing gently to ensure thorough soaking.
05 - In a medium bowl, beat softened cream cheese, sugar, egg yolk, and vanilla extract until smooth and creamy.
06 - Dollop the cream cheese mixture by spoonfuls over the soaked bread layer.
07 - Top with remaining bread cubes, then pour the remaining custard over the top. Gently press to ensure all bread is fully moistened.
