Creating Cinnamon Roll Bread Pudding with Bourbon Sauce is a simple process. Follow these steps to make this delicious dessert:

1. Preheat the Oven: Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking dish.

2. Prepare the Cinnamon Rolls: Cut each cinnamon roll into quarters and place them in the greased baking dish. If using, sprinkle the chopped pecans and raisins evenly over the rolls.

3. Make the Custard: In a large mixing bowl, whisk together the eggs, whole milk, heavy cream, granulated sugar, vanilla extract, ground cinnamon, and salt until well combined.

4. Combine: Pour the custard mixture evenly over the cinnamon roll pieces in the baking dish. Press down gently to ensure all pieces are soaked.

5. Bake: Place the baking dish in the preheated oven and bake for 45 minutes or until the top is golden brown and a toothpick inserted into the center comes out clean.

6. Cool: Once baked, remove the dish from the oven and allow it to cool for about 10 minutes before serving.

7. Prepare the Bourbon Sauce: While the bread pudding is cooling, make the bourbon sauce by melting the butter in a saucepan over medium heat. Add the brown sugar, heavy cream, and bourbon. Stir until the mixture is smooth and well combined, and bring to a simmer. Cook for 2-3 minutes until slightly thickened. Remove from heat and stir in the vanilla extract.

8. Serve: Serve the warm bread pudding with a generous drizzle of bourbon sauce on top.
