Making Bread Pudding with Bourbon Sauce is simple when you follow these steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C).
2. Prepare Bread: Place the cubed bread in a large mixing bowl and set aside.
3. Mix Wet Ingredients: In another bowl, whisk together the eggs, milk, heavy cream, granulated sugar, vanilla extract, cinnamon, nutmeg, and salt until well combined.
4. Combine Mixtures: Pour the wet mixture over the cubed bread, gently folding to ensure all pieces are soaked. Let it sit for about 15 minutes.
5. Add Mix-Ins: If using raisins or chocolate chips, fold them into the bread mixture now.
6. Transfer to Baking Dish: Grease a 9×13-inch baking dish and pour the bread pudding mixture into it, spreading it evenly.
7. Bake: Bake in the preheated oven for 30-40 minutes, or until the pudding is set and the top is golden brown.
8. Cool: Once baked, remove the dish from the oven and allow it to cool for about 10-15 minutes.
9. Prepare Bourbon Sauce: While the pudding cools, whisk together the powdered sugar, melted butter, bourbon, and vanilla extract in a separate bowl until smooth.
10. Serve: Drizzle the warm bourbon sauce over the cooled bread pudding before serving.
