1. Preheat oven to 400°.
2. Combine first 5 ingredients in a large bowl, tossing to coat. Spoon mixture into an 11 x 7-inch glass or ceramic baking dish coated with cooking spray.
3. Place brown sugar and next 4 ingredients (through graham crackers) in a food processor; pulse until crackers are coarsely chopped. Add melted buttery spread; pulse 6 to 7 times or until combined.
4. Spoon brown sugar mixture over apples. Bake at 400° for 25 to 30 minutes or until topping is browned and crisp and apples are tender. Top each serving with whipped topping; sprinkle with cinnamon, if desired.
