Preheat oven to 300°.
Place sugar in a medium, heavy skillet over medium heat; cook until sugar dissolves. Continue cooking an additional 1 1/2 minutes or until golden. Immediately pour into a 9-inch quiche dish coated with cooking spray, tipping quickly until caramelized sugar coats bottom of dish.
Combine 1% milk and remaining ingredients in a food processor, and process mixture until smooth. Pour milk mixture over caramelized syrup in dish. Place dish in a shallow roasting pan, and add hot water to pan to a depth of 1 inch. Bake at 300° for 1 hour or until a knife inserted in center of flan comes out clean. Remove dish from roasting pan, and cool 30 minutes on a wire rack. Cover flan, and chill at least 3 hours. Place a plate upside down on top of dish, and invert flan onto plate. Drizzle any remaining caramelized syrup over the flan.
