A light and refreshing Sunny Pineapple Orange Cake made with yellow cake mix, mandarin oranges, vanilla pudding, and crushed pineapple, finished with a creamy whipped topping.
Preheat the oven to 350°F (175°C). Grease and flour two 9-inch round cake pans. In a large mixing bowl, combine the yellow cake mix, eggs, pudding mix, drained mandarin oranges, orange extract, and oil. Mix until smooth and well combined.
Bake the Cake
Divide the batter evenly between the two prepared pans. Bake for 20–25 minutes, or until a toothpick inserted into the center comes out clean. Allow cakes to cool completely before assembling.
Prepare the Topping
In a medium bowl, combine the crushed pineapple with the pudding mix. Gently fold in the whipped topping until light and fluffy. Ensure the mixture is evenly blended.
Assemble the Cake
Place one cooled cake layer on a serving plate. Spread a layer of the prepared topping evenly over the surface. Add the second cake layer on top and frost the top and sides with the remaining topping.
Garnish and Serve
Garnish with mandarin orange segments and additional pineapple pieces if desired. Chill for at least 30 minutes before serving to allow the flavors to set.
