Pistachio Pineapple Cake

I still remember the first time I made this Pistachio Pineapple Cake—it was an experiment inspired by a potluck dish I couldn’t stop thinking about. I wanted something vibrant, nostalgic, and ridiculously easy, and this cake checked every box. It’s light, moist, and infused with the sweetness of crushed pineapple and the subtle nuttiness of pistachio pudding. And that soft green hue? It’s cheerful, unexpected, and instantly makes people ask, “What’s in this?”

What I love most is that it’s a one-bowl kind of dessert. No complicated layers or intimidating techniques—just a simple cake base topped with a creamy whipped frosting that’s equally refreshing and indulgent. Whether you’re making it for a holiday, a picnic, or just a sweet craving that won’t quit, this cake delivers every single time.

Why You’ll Love This Pistachio Pineapple Cake

This cake isn’t just pretty—it’s incredibly flavorful. The crushed pineapple keeps it moist without being dense, while the pistachio pudding gives it a creamy, nutty twist that pairs so well with the whipped topping. It’s make-ahead friendly, travels well, and can be sliced into perfect little squares for sharing. Plus, it’s one of those rare cakes that feels light but still satisfies your sweet tooth. If you like easy recipes with major payoff, this one is for you.

What Kind of Cake Mix Should I Use for Pistachio Pineapple Cake?

For this recipe, a simple yellow cake mix works beautifully. It’s neutral enough to let the pistachio and pineapple flavors shine while providing a moist, fluffy base that holds everything together. You can also use white cake mix if that’s what you have—it gives a slightly lighter color and texture. I wouldn’t recommend chocolate or spice cake mixes here, as they overpower the delicate tropical notes of the recipe.

If you’re feeling adventurous, you can even try a pineapple or vanilla cake mix to enhance the fruit-forward flavor. Just be mindful of the sugar content if you’re adjusting the type—some mixes are sweeter than others.

Options for Substitutions

• Cake Mix: Yellow cake mix is the go-to, but white or vanilla also work. For a gluten-free version, use your favorite gluten-free cake mix.
• Crushed Pineapple: Fresh pineapple won’t give the same results as canned—stick to canned crushed pineapple with juice for the right texture and moisture.
• Pistachio Pudding Mix: Instant pudding is key here. If you only have cook-and-serve pudding, the texture won’t be right. You can experiment with coconut pudding for a tropical variation, though it’ll change the flavor.
• Cool Whip: If you prefer homemade whipped cream, it can be substituted—just make sure it’s stable enough to hold up in the fridge.
• Eggs and Oil: You can replace eggs with unsweetened applesauce or a flax egg if you’re going egg-free. Swap oil for melted butter or even Greek yogurt for a richer, tangier bite.

Ingredients for this Pistachio Pineapple Cake

• Yellow Cake Mix
  This is the foundation of the cake. It’s soft, moist, and neutral in flavor—perfect for letting the pistachio and pineapple shine.
• Instant Pistachio Pudding Mix
  This adds that signature nutty flavor and a pale green hue. It also makes the cake extra moist and tender.
• Crushed Pineapple (with juice)
  Not only does it keep the cake light and juicy, but it also brings a subtle tropical sweetness that pairs beautifully with pistachio.
• Eggs
  They bind everything together and help the cake rise properly in the oven.
• Vegetable Oil
  This gives the cake its soft, moist texture and ensures it stays that way for days.
• Cool Whip (or whipped topping)
  Used in the frosting, it adds a light, airy texture without making the cake feel heavy.
• Milk
  Just a bit of milk is mixed into the topping for creaminess and smooth spreading.
• Another box of Instant Pistachio Pudding Mix (for the frosting)
  Yes, it goes into the frosting too! It creates a fluffy, stabilized topping with even more pistachio flavor.

Step 1: Preheat and Prep

Start by preheating your oven to 350°F (175°C). Lightly grease a 9×13-inch baking pan or line it with parchment paper for easy removal.

---

Step 2: Mix the Cake Batter

In a large mixing bowl, combine the yellow cake mix, one box of instant pistachio pudding mix, the entire can of crushed pineapple (juice included), eggs, and vegetable oil. Mix until everything is well incorporated and smooth—don’t overmix, but make sure there are no dry spots.

---

Step 3: Bake

Pour the batter evenly into the prepared baking pan and smooth the top. Bake for 30–35 minutes, or until a toothpick inserted in the center comes out clean. Let the cake cool completely in the pan on a wire rack.

---

Step 4: Make the Frosting

In another bowl, combine the second box of instant pistachio pudding mix with cold milk. Whisk until it starts to thicken slightly, then gently fold in the Cool Whip. This creates a fluffy, mousse-like frosting.

---

Step 5: Frost the Cake

Once the cake is completely cool, spread the pistachio frosting evenly over the top. Use a spatula to create soft swirls for that pretty, homemade look.

---

Step 6: Chill and Serve

Refrigerate the frosted cake for at least 1 hour before serving. This helps the frosting set and makes the cake even easier to slice into neat squares.

How Long to Cook the Pistachio Pineapple Cake

The baking time for this cake is typically 30 to 35 minutes in a 350°F (175°C) oven. You’ll know it’s done when the center is set, the edges are lightly golden, and a toothpick inserted in the middle comes out clean.

Be careful not to overbake—it should be moist and fluffy, not dry. If your oven runs hot or cool, keep an eye on it around the 28-minute mark to avoid overcooking.

Tips for Perfect Pistachio Pineapple Cake

• Use the Pineapple Juice: Don’t drain the crushed pineapple! The juice is essential for both flavor and moisture.
• Don’t Overmix: Stir the batter just until everything is combined. Overmixing can make the cake dense.
• Cool Completely Before Frosting: If the cake is warm, the whipped topping will melt and slide off.
• Use Instant Pudding Only: Cook-and-serve pudding won’t work for the frosting or the batter—it won’t set right.
• Chill Before Serving: Refrigerating the cake for at least an hour helps the flavors meld and makes cutting easier.
• Smooth the Frosting with a Spoon or Spatula: For that pretty swirl effect, gently run the back of a spoon over the top.
• Use a Serrated Knife for Clean Slices: This will help you get those crisp, bakery-style square cuts.

Watch Out for These Mistakes While Cooking

• Using Cook-and-Serve Pudding Mix Instead of Instant
  This is the most common mistake. Cook-and-serve pudding requires heat to thicken, so it won’t work in this no-cook frosting or cake batter.
• Draining the Crushed Pineapple
  The juice is crucial! It adds flavor and the necessary liquid to the batter. Always use the entire can, juice and all.
• Frosting a Warm Cake
  Let the cake cool completely before adding the whipped topping. If it’s even slightly warm, the frosting will melt and turn soupy.
• Overbaking the Cake
  Keep a close eye on the oven. Overbaking will dry out the cake and take away its soft, tender texture.
• Using Fresh Pineapple Instead of Canned
  Fresh pineapple has enzymes that can interfere with the pudding setting and also lacks the same moisture content. Stick to canned crushed pineapple.
• Skipping the Chill Time
  This cake tastes best when chilled. Don’t rush it—give it at least an hour in the fridge before slicing.

What to Serve With Pistachio Pineapple Cake?

Fresh Berries

A side of strawberries, blueberries, or raspberries offers a juicy contrast to the creamy texture of the cake.

Vanilla Ice Cream

A scoop of classic vanilla makes this even more indulgent. The cold, creamy texture pairs perfectly with the chilled cake.

Mint Iced Tea

Something refreshing like mint or citrus iced tea helps cleanse the palate between bites.

Toasted Coconut

Sprinkle some on top or serve on the side for added tropical flair and a bit of crunch.

Whipped Cream and Chopped Pistachios

A little extra whipped topping and a handful of pistachios give each slice a more decadent finish.

Lemon Curd or Citrus Drizzle

A tart lemon drizzle adds a zesty twist and brings out the pineapple flavor even more.

Graham Cracker Crumbs

For a crunchy side element, serve with a sprinkle of graham cracker crumbs—it gives the dish a pie-like vibe.

Espresso or Strong Coffee

The bitterness of coffee contrasts beautifully with the cake’s sweetness—ideal for an afternoon treat.

Storage Instructions

Pistachio Pineapple Cake stores wonderfully, making it perfect for making ahead or enjoying over a few days. Here’s how to keep it fresh:

• Refrigerator: Store the cake in an airtight container or cover the baking dish tightly with plastic wrap. It will stay fresh in the fridge for up to 5 days. The whipped topping holds up well, and the flavors actually get better after a day or two.
• Freezer: You can freeze the cake before frosting it. Wrap the cooled cake tightly in plastic wrap, then in foil, and freeze for up to 2 months. When ready to serve, thaw overnight in the fridge, then make and apply the frosting fresh.
• After Frosting: If you’ve already frosted it, freezing is not ideal—the whipped topping texture may change. It’s best to keep it chilled and eat within a few days.

Frequently Asked Questions

Can I make Pistachio Pineapple Cake ahead of time?

Yes! In fact, it tastes even better the next day. Make it a day in advance and refrigerate until serving.

Can I use fresh pineapple instead of canned?

It’s not recommended. Fresh pineapple contains enzymes that can prevent the pudding from setting and lacks the consistent moisture of canned crushed pineapple.

Do I have to use Cool Whip, or can I use real whipped cream?

You can use real whipped cream, but make sure it’s stabilized (add a bit of cream cheese or gelatin) so it doesn’t deflate or weep in the fridge.

Can I make this cake gluten-free?

Absolutely. Just swap in your favorite gluten-free yellow or vanilla cake mix and double-check that the pudding mix is gluten-free too.

How long does this cake last in the fridge?

It’ll stay fresh for up to 5 days when stored properly in the refrigerator.

Can I bake this in round cake pans or as cupcakes?

Yes! Just adjust the baking time accordingly. Cupcakes will take around 18–22 minutes, and round pans will bake closer to 25–30 minutes depending on size.

Is the green color natural?

The color comes from the pistachio pudding mix, which is tinted green. It’s subtle and festive, especially around holidays like Easter or Christmas.

Can I add nuts or coconut to the batter?

Definitely! Chopped pistachios or shredded coconut are both great additions for extra texture and flavor.
