Banana Pudding Créme Brulée Cake Custard Base

Make the Custard Base:

1. In a saucepan, combine heavy cream and milk. Bring to a gentle simmer over medium heat.
2. Meanwhile, whisk together egg yolks, granulated sugar, mashed ripe banana, vanilla extract, and salt in a mixing bowl.
3. Temper the yolk mixture by slowly adding the hot cream, whisking constantly.
4. Strain the mixture through a fine sieve into a clean container to remove solids and create a smooth custard.
