Making Cinnamon Raisin Bread Pudding is a straightforward process. Follow these steps for a delightful dessert:

1. Preheat Oven: Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with butter or cooking spray.
2. Prepare Bread: In a large bowl, combine the cubed bread and raisins. Toss gently to mix.
3. Whisk Eggs: In another bowl, whisk together the eggs, whole milk, heavy cream, granulated sugar, vanilla extract, ground cinnamon, and salt until well combined.
4. Combine Mixtures: Pour the egg mixture over the bread and raisins. Stir gently to ensure all the bread is soaked in the liquid. Let it sit for about 10 minutes to absorb.
5. Add Butter: Drizzle the melted butter over the mixture and gently fold it in until evenly distributed.
6. Transfer to Baking Dish: Pour the bread mixture into the prepared baking dish, spreading it out evenly.
7. Bake: Place in the preheated oven and bake for 45-50 minutes, or until the top is golden brown and a toothpick inserted in the center comes out clean.
8. Cool: Once baked, remove from the oven and let it cool for about 10-15 minutes before serving.
9. Dust with Powdered Sugar: If desired, dust the top with powdered sugar for a beautiful presentation.
