Making King Cake Bread Pudding is a straightforward process if you follow these simple steps:

1. Prepare the Bread: If using brioche bread, cut it into 1-inch cubes. If using king cake, cut it into 1-inch pieces.
2. Preheat the Oven: Set your oven to 350°F (175°C). Grease a 9×13-inch baking dish.
3. Mix the Eggs: In a large bowl, whisk together the eggs until well beaten.
4. Combine Dairy: Add the whole milk, heavy cream, sugar, vanilla extract, cinnamon, nutmeg, and salt to the eggs. Whisk until well combined.
5. Add Bread: Gently fold the bread cubes into the egg mixture, ensuring all pieces are well-coated. Let it sit for about 10 minutes to absorb the custard.
6. Transfer to Dish: Pour the bread mixture into the prepared baking dish, spreading it evenly.
7. Bake: Place the dish in the preheated oven and bake for 40-45 minutes, or until the top is golden brown and set in the middle.
8. Cool: Remove from the oven and let it cool for about 15-20 minutes before serving.
9. Garnish: If desired, top with colorful sprinkles for a festive touch.
