Creating the perfect Cinnamon Vanilla Bread Pudding with Warm Butter Sauce is a simple process. Follow these easy steps to ensure a delightful result:

1. Preheat your oven to 350°F (175°C).
2. Prepare the Bread: Tear the loaf of bread into bite-sized pieces and place them in a large mixing bowl. If using, add the raisins and chopped nuts.
3. Make the Custard: In another bowl, whisk together the eggs, milk, heavy cream, granulated sugar, vanilla extract, cinnamon, and salt until well combined.
4. Combine Mixtures: Pour the custard mixture over the torn bread pieces. Gently stir and press down to ensure all pieces are soaked.
5. Let it Soak: Allow the mixture to sit for about 15 minutes so the bread fully absorbs the custard.
6. Grease the Baking Dish: Lightly butter a 9×13-inch baking dish.
7. Transfer the Mixture: Spoon the soaked bread mixture into the prepared baking dish evenly.
8. Bake: Place in the oven and bake for 45-50 minutes, or until the top is golden and a knife inserted in the center comes out clean.
9. Cool Slightly: Once baked, remove from the oven and let it cool for about 10-15 minutes.
10. Prepare the Warm Butter Sauce: In a small saucepan over low heat, melt the butter. Stir in the powdered sugar, heavy cream, and vanilla extract until smooth.
11. Serve Warm: Drizzle the warm butter sauce over the pudding before serving.
