Preheat oven to 350 degrees F. Liberally grease a 13x9" baking pan with cooking spray and set aside.

In a large bowl, beat together the cake mix, fruit topping, eggs and cinnamon until blended, about 2 minutes. Batter will be thick. Spread into the prepared pan in an even layer.

Bake for approx. 30-35 minutes or until a toothpick inserted near the center comes out clean or with moist crumbs. Cool the cake completely. Serve with whipped cream and caramel drizzle if you'd like!
