Creating Cinnamon Bread Pudding is a straightforward process that yields delightful results. Follow these simple steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking dish with butter.
2. Cube the Bread: Cut the day-old bread into 1-inch cubes. Place the cubes into the prepared baking dish.
3. Prepare the Custard Mixture: In a large mixing bowl, whisk together the eggs, milk, heavy cream, granulated sugar, vanilla extract, ground cinnamon, and salt until well combined.
4. Combine Bread and Custard: Pour the custard mixture over the bread cubes, ensuring all pieces are soaked. Use a spatula to gently press the bread down if necessary.
5. Add Optional Ingredients: If desired, sprinkle raisins or chocolate chips over the soaked bread mixture for added flavor.
6. Bake: Place the baking dish in the preheated oven and bake for 30-40 minutes, or until the top is golden and a toothpick inserted in the center comes out clean.
7. Cool: Remove from the oven and let the pudding cool for about 10-15 minutes before serving.
8. Serve Warm: Serve warm with a drizzle of cream, a scoop of ice cream, or a dusting of powdered sugar.
