Cut a day old loaf of french bread into one-inch chunks. Place the chunks in a large glass casserole dish that has been coated in non-stick spray. Sprinkle with raisins.
In a bowl combine the pumpkin puree, eggs, brown sugar, cinnamon, pumpkin pie spice and vanilla. Stir until evenly combined. Whisk in the milk.
Pour the pumpkin/milk mix over the bread cubes and give it a gentle stir to coat the cubes. Preheat the oven to 350 degrees. Let the bread cubes soak in the pumpkin mix as the oven heats.
Bake the bread pudding for 40-45 minutes or until the center has set (poke with a toothpick, it should come out clean). Serve with maple syrup, whipped cream, vanilla yogurt or caramel sauce.
