In a large bowl stir together first six ingredients (through cinnamon). In a medium bowl combine egg, milk, applesauce, both sugars, and oil. Stir egg mixture into oat mixture until combined. Gently stir in fruit. Cover and chill 12 to 24 hours.
Preheat oven to 350 degrees F. Coat a 2-qt. square or rectangular baking dish with cooking spray. Spoon oat mixture into prepared dish.
Bake 45 to 50 minutes or until top is brown. Cool slightly. Serve warm with yogurt and, if desired, additional fruit.
