Creating Classic Bread Pudding Recipe with Warm Vanilla Sauce is simple if you follow these steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish or individual ramekins with butter.

2. Prepare the Bread: Place the cubed bread in a large mixing bowl. If using raisins, sprinkle them over the bread cubes.

3. Mix the Custard: In a separate bowl, whisk together the eggs, milk, heavy cream, sugar, vanilla extract, cinnamon, and salt until well combined.

4. Combine Bread and Custard: Pour the custard mixture over the bread cubes. Gently stir to ensure all the bread is coated. Let it sit for about 10-15 minutes to allow the bread to soak up the custard.

5. Transfer to Baking Dish: Pour the soaked bread mixture into the prepared baking dish, spreading it evenly.

6. Bake: Bake in the preheated oven for 45 minutes, or until the top is golden brown and a knife inserted in the center comes out clean.

7. Make the Warm Vanilla Sauce: While the bread pudding is baking, prepare the sauce. In a saucepan, combine heavy cream, sugar, and cornstarch over medium heat. Stir until the mixture thickens. Remove from heat and stir in vanilla extract and a pinch of salt.
