Ingredients

For the Cake:
- 1 box yellow cake mix (15.25 oz)
- 4 large eggs
- 1/2 cup vegetable oil
- 1 can (11 oz) mandarin oranges (with juice)
For the Frosting:
- 1 container (8 oz) whipped topping (Cool Whip)
- 1 package (3.4 oz) instant vanilla pudding mix
- 1 can (20 oz) crushed pineapple (with juice)
Instructions

Step 1: Make the Cake
- Preheat oven to 350°F (175°C). Grease and flour a 9×13-inch baking dish.
- In a large bowl, mix cake mix, eggs, oil, and the entire can of mandarin oranges (including juice).
- Beat on medium speed for 2–3 minutes until light and fluffy—the oranges will break up into the batter.
- Pour into the prepared pan and bake for 30–35 minutes or until a toothpick inserted comes out clean.
- Let the cake cool completely.
Step 2: Make the Frosting
- In a bowl, mix the dry pudding mix with the crushed pineapple and its juice until thickened (1–2 minutes).
- Fold in the whipped topping until smooth and fully combined.
- Spread the frosting evenly over the cooled cake.
Chill & Serve
Refrigerate the cake for at least 1 hour before serving for the best texture and flavor.
