Preheat oven to 350ºF and spray a 9-inch springform pan with baking spray.

Add the cake mix and Sunkist together and stir until just combined. {Don't over mix}. Pour the batter into your prepared pan and set aside.

In a medium bowl, whip the cream cheese until smooth. Add the powdered sugar and mix until fully incorporated. Then add the orange juice and orange zest until well combined.

Pour the cream cheese mixture over the cake batter and swirl a few times with a spoon or spatula.

Bake the cake for 32-35 minutes or until you can insert a toothpick in the center and it comes out clean. Let the cake cool completely.

Spread the whipped topping evenly over the cake so as to coat all of it and then top with your orange slices.
