Step 1

Preheat the oven to 350°F. In a large bowl, use a hand mixer or stand mixer to beat the cake mix, oranges, egg whites and applesauce on low speed for two minutes.

Step 2

Grease a 13x9-inch baking dish with cooking spray. Pour in the batter. Using a mini offset spatula or the back of a spoon, evenly spread the cake batter in the dish.

Step 3

Bake the cake until a toothpick inserted in the center comes out clean, 25 to 30 minutes. Cool the cake completely to room temperature on a wire rack.

Step 4

In a bowl, whisk together the pineapple and pudding mix. Fold in the whipped topping just until blended.

Step 5

Spread the topping over the cooled cake. Using the back of a spoon or a mini offset spatula, create swoops in the topping to add more dimension. Refrigerate the cake for at least one hour before serving.
