Ingredients

Scale

For the Cake:

1 box yellow cake mix (approximately 15.25 oz)

1 can (20 oz) crushed pineapple in juice, undrained

3 large eggs

½ cup vegetable oil

For the Topping:

1 tub (8 oz) whipped topping (e.g., Cool Whip), thawed

1 package (3.4 oz) instant vanilla pudding mix

1 can (20 oz) crushed pineapple in juice, undrained

Instructions

Step 1: Preheat and Prep

  • Preheat your oven to 350°F (175°C).

  • Lightly grease a 9×13-inch baking dish with butter or non-stick spray.

Step 2: Mix the Cake Batter

  • In a large mixing bowl, combine:

    • 1 box yellow cake mix

    • 1 can (20 oz) crushed pineapple with juice

    • 3 large eggs

    • ½ cup vegetable oil

  • Beat using a hand mixer or whisk for 2–3 minutes until smooth and well combined.

Step 3: Bake the Cake

  • Pour the batter into the prepared 9×13 pan.

  • Bake for 30–35 minutes, or until a toothpick inserted in the center comes out clean.

  • Let the cake cool completely in the pan.

Step 4: Prepare the Topping

  • In a medium mixing bowl, fold together:

    • 1 tub (8 oz) whipped topping

    • 1 package (3.4 oz) instant vanilla pudding mix

    • 1 can (20 oz) crushed pineapple with juice

  • Mix until fully blended and fluffy.

Step 5: Assemble the Cake

  • Once the cake has cooled, spread the pineapple topping evenly over the entire surface.

  • Refrigerate the cake for at least 1 hour before slicing and serving.

Notes

  • Don’t drain the pineapple: The juice is essential for moisture and flavor in both the cake and topping.

  • Use only canned pineapple in juice, not syrup, for balanced sweetness.

  • For a tangy twist, swap the vanilla pudding with lemon or coconut instant pudding.

  • You can add 1/2 cup shredded coconut or chopped nuts to the topping for extra texture.

  • Fresh pineapple is not recommended unless cooked and adjusted for liquid content.

  • If you’re freezing, freeze the baked cake only and add topping after thawing.
