5. Transfer to Baking Dish: Pour the mixture into the prepared baking dish, spreading it evenly.
6. Bake: Place in the preheated oven and bake for 45-50 minutes or until the top is golden brown and a knife inserted in the center comes out clean.
7. Cool: Allow the bread pudding to cool for about 15-20 minutes before drizzling with bourbon sauce.
