Pineapple Paradise Cake: The Easy Pistachio and Pineapple Cake You Need to Make
This Pineapple Paradise Cake is more than just a dessert; it’s a time machine disguised as a 9×13 pan. It’s a bright, nostalgic, and unbelievably easy cake that brings together the tangy sweetness of crushed pineapple with the subtle, nutty warmth of pistachio. If you grew up with a classic Watergate Salad or Pistachio Fluff, this is the cake version of that beloved, creamy, vibrant green goodness, but taken to an elevated, crowd-pleasing level.
I love a recipe that promises big flavor with minimal fuss, and this one delivers. We’re using a box of angel food cake mix as a shortcut, which makes the cake itself incredibly light and airy—the perfect foil for the rich, fruity batter. Then, it’s topped with a thick, dreamy frosting made from Cool Whip and more pistachio pudding. The result is a moist, tender crumb that practically melts in your mouth, chilled to perfection, and ready to be the star of your next potluck, BBQ, or Sunday dinner.
Why I Love This Recipe
I first made a version of this cake years ago for a family reunion, and it disappeared faster than any complicated, scratch-made dessert I’ve ever attempted. It’s a no-fail recipe, even for the most beginner baker. Here’s why it has earned a permanent spot in my rotation:
- Effortless Elegance: It looks fancy with its light green hue and chopped pistachios, but the prep time is laughably short. The oven does all the heavy lifting.
- The Perfect Texture: The addition of crushed pineapple with its juices keeps the cake intensely moist and infuses it with a deep tropical flavor that balances the pistachio perfectly.
- It’s a Crowd-Pleaser: People go absolutely wild for this Cool Whip and pistachio pudding frosting. It’s light, creamy, and irresistibly nostalgic.
- Make-Ahead Magic: It actually tastes better the next day after it’s had time to chill in the refrigerator, making it the ideal dessert for entertaining. You’ll also love other make-ahead desserts like my recipe for Big Family Banana Pudding for when you need to feed a crowd.

Swaps and Notes
- Cake Mix: You can swap the Angel Food Cake Mix for a White Cake Mix or Yellow Cake Mix for a denser crumb, but you may need to adjust the baking time slightly.
- Oil: Canola oil or coconut oil (melted) work just as well as vegetable oil.
- Pudding Flavor: While the pistachio is classic, you could experiment with a cheesecake-flavored or vanilla pudding mix if you want a different flavor profile, though you’ll lose the signature green color.
- Toppings: For an extra tropical flair, top with toasted coconut flakes instead of pistachios.
Steps for the Recipe
Follow these simple steps for a perfect Pineapple Paradise Cake.
Step 1: Prep the Oven and Pan
Preheat your oven to 350∘F (175∘C) and grease a 9×13 inch baking dish. This helps ensure a clean release when serving.
Step 2: Mix the Cake Batter
In a large mixing bowl, combine the cake mix, one box of the pistachio pudding mix, vegetable oil, eggs, and the entire can of crushed pineapple with all of its juices. Beat the mixture until it is smooth and well combined. A hand mixer makes this quick, but a whisk works too.
Step 3: Bake the Cake
Transfer the vibrant green batter to your prepared baking dish. Spread it into an even layer. Bake for 30–35 minutes, or until a toothpick inserted into the center comes out clean.
Step 4: Cool Completely
Allow the cake to cool completely on a wire rack. This is crucial! Frosting a warm cake will cause the Cool Whip to melt.
Step 5: Make the Frosting
In a separate bowl, whisk together the second box of pistachio pudding mix and the cold whole milk until the mixture begins to thicken. This will only take about 1–2 minutes.
Step 6: Fold and Frost
Gently fold the thawed Cool Whip into the thickened pudding mixture until it’s fully combined and you have a light, fluffy green frosting. Spread the frosting evenly over the cooled cake.
Step 7: Chill and Serve
Cover the cake and chill for at least 2 hours before serving. This allows the frosting to set and the flavors to fully meld. Before slicing, top with chopped pistachios if desired.
Tips for Success
- Cool Whip Must Be Thawed: Take your Cool Whip out of the freezer and let it thaw in the refrigerator for several hours or overnight. Using it frozen or semi-frozen will result in a lumpy, inconsistent frosting.
- Don’t Drain the Pineapple: The pineapple juice is the secret to this cake’s incredible moisture and flavor. Draining it will make your cake dry.
- Chilling is Mandatory: This is a chilling cake! The texture and flavor improve dramatically after it has sat in the refrigerator. Plan to make this dessert the day before you plan to serve it.
- Use Instant Pudding: Be sure you are using instant pistachio pudding mix, not the cook-and-serve variety.
Serving Suggestions and Pairings
This cake is excellent on its own, but a little something extra never hurt!
- Beverage Pairings: Nothing complements the tropical vibe of this cake like a refreshing drink. Pair a slice with a glass of chilled iced tea or my favorite recipe for Blueberry Lemonade.
- Topping Ideas: A dollop of extra whipped cream or a scoop of vanilla ice cream makes this cake feel even more decadent.
- Dessert Bar: If you’re hosting a party, serve this alongside other fun, sweet treats like These Chocolate Chip Cookie Dough Brownie Bombs or my Unicorn Poke Cake.

Storage and Leftover Tips
This cake stores beautifully, which is why it’s a great choice for family events.
- Refrigeration: Store any leftovers in an airtight container in the refrigerator for up to 4–5 days. Since the frosting is Cool Whip-based, it must be kept cold.
- Freezing: I don’t recommend freezing this cake, as the Cool Whip frosting can separate and weep when thawed, affecting the texture.
