Preheat oven to 350°.
Combine first 6 ingredients in a large bowl, stirring with a whisk. Add bread, pressing down with a spatula to soak. Spoon bread mixture into a 2-quart baking dish coated with cooking spray. Bake at 350° for 50 minutes. Drizzle with caramel syrup, and sprinkle with nuts. Bake an additional 5 minutes or until caramel syrup is bubbly.
Place chocolate chips in a small glass bowl or heavy-duty zip-top bag; microwave at high for 30 seconds or until melted. Drizzle over the bread pudding. Serve warm.
