Making Brioche Bread Pudding is simple and rewarding. Follow these steps to create this delightful dessert:

1. Preheat Oven: Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with butter.
2. Prepare Bread: In a large bowl, combine the cubed brioche bread and set aside.
3. Mix Wet Ingredients: 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 cubed brioche bread. Gently fold to combine, ensuring all bread pieces are soaked.
5. Add Optional Ingredients: If desired, fold in raisins or chocolate chips for added flavor.
6. Transfer to Baking Dish: Pour the mixture into the prepared baking dish, spreading it evenly.
7. Bake: Place in the preheated oven and bake for 40-45 minutes or until the top is golden brown and a toothpick inserted in the center comes out clean.
8. Cool: Allow to cool for about 5-10 minutes before serving. This allows the pudding to set slightly.
9. Dust with Powdered Sugar: Optionally, dust the top with powdered sugar for an elegant touch before serving.
