Begin by preheating your oven to 350 degrees F. While the oven is heating up, take two loaves of Brioche and cut them into approximately 1-inch cubes.
Now it’s time to create the custard mixture. In a saucepan over medium heat, combine heavy cream, milk, butter and split vanilla beans. Allow the mixture to come to a simmer, then turn off the heat. Next, add in chunks of high-quality white chocolate and stir until fully melted and well combined.
In a large mixing bowl, take 16 eggs and whisk them together with sugar until they are thoroughly combined. Slowly pour in the creamy custard mixture while continuously whisking to prevent any lumps from forming.
Take the prepared Brioche cubes and spread them evenly in a large baking dish. Then, slowly pour the custard mixture over the bread, ensuring that each cube is fully coated with the creamy mixture.
Place the baking dish in the preheated oven and bake for 35-40 minutes, or until the top of the bread pudding is a beautiful golden brown and the custard has set. Serve this delectable treat warm with a dollop of whipped cream or a scoop of vanilla ice cream for an extra indulgent touch.
