Ingredients You’ll Need

You probably already have most of these pantry staples. Here’s what to grab:

For the Cake:

1 box yellow cake mix – Your favorite brand works fine.
1 can (20 oz) crushed pineapple in juice, undrained – Adds both moisture and flavor.
3 large eggs – Provides structure and richness.
1/2 cup vegetable oil – Keeps the crumb soft and tender.

For the Topping:

1 tub (8 oz) whipped topping (like Cool Whip) – Light, airy, and so easy.
1 package (3.4 oz) instant vanilla pudding mix – Adds flavor and helps firm up the topping.
1 can (20 oz) crushed pineapple in juice, undrained – Yep, another one! This is what gives the topping its zing.

How to Make Juicy Pineapple Heaven Cake

You don’t need to be a pro baker to make this masterpiece. Follow these easy steps:

Step 1: Prep the Oven and Pan

Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with cooking spray or butter to ensure the cake lifts out smoothly.

Step 2: Mix the Cake Batter

In a large mixing bowl, combine:

The yellow cake mix
1 can of crushed pineapple with all its juice
3 eggs
1/2 cup vegetable oil

Use a hand mixer or whisk to blend everything until smooth. No need to over-mix—just get rid of lumps.

Step 3: Bake to Golden Perfection

Pour the batter into your prepared pan and smooth the top with a spatula. Bake for 30–35 minutes, or until a toothpick inserted in the center comes out clean.

Set aside to cool completely in the pan. This part is crucial because the topping won’t set right if the cake is warm.

Step 4: Prepare the Whipped Pineapple Topping

In a medium bowl, gently fold together:

The whipped topping
Instant vanilla pudding mix
The second can of crushed pineapple, juice and all

Stir until you have a thick, creamy mixture that’s flecked with pineapple throughout. Try not to eat it all with a spoon before it hits the cake!

Step 5: Top and Chill

Once the cake is completely cool, spread the pineapple topping evenly over the surface. Cover with plastic wrap or foil, then refrigerate for at least 1 hour—overnight is even better.

Slice into 12 generous portions and get ready to impress.
