Preheat oven to 375 degrees F. Lightly coat six 6-ounce ramekins or custard cups with cooking spray; set aside. In a large bowl whisk together egg whites, whole egg, pumpkin, milk, 2 tablespoons syrup, the cinnamon, salt, nutmeg, and cloves. Stir in bread pieces and pecans.
Divide mixture among prepared custard cups. Arrange custard cups in a shallow baking pan. Bake about 25 minutes or until lightly browned on top and heated through (160 degrees F in centers). Cool slightly. Serve warm topped with butter and remaining syrup.
