Pineapple Pistachio Cake bakes up incredibly moist, pistachio-green and tropical, then gets crowned with fluffy pistachio pudding frosting for a potluck-ready crowd pleaser.
If you love a dessert that tastes like sunshine but requires almost no effort, this is your cake. A yellow cake mix teams up with instant pistachio pudding and a full can of crushed pineapple (juices and all) to deliver tender crumbs and gentle pistachio flavor with citrusy, juicy lift. No complicated techniques—just stir, bake, cool, and frost.
The frosting leans into that pistachio theme with more pudding mix whisked into a blend of half-and-half and heavy cream, then lightened with whipped topping. It sets up cloud-soft, slices cleanly after a chill, and begs for a sprinkle of chopped pistachios on top.
What You Need to Make This Pineapple Pistachio Cake
For the cake
- Yellow cake mix — Reliable structure and buttery vanilla backdrop that lets pistachio and pineapple shine.
- Instant pistachio pudding mix — Adds color, pistachio flavor, and a plush, ultra-moist crumb.
- Neutral oil — Keeps the cake tender for days without greasiness.
- Eggs — Bind and lift for a fine, even crumb.
- Crushed pineapple (undrained) — Provides juicy sweetness and moisture; the syrupy juices replace extra liquid.
For the pistachio frosting
- Half-and-half — Milky base that hydrates the pudding without heaviness.
- Heavy cream — A touch of richness so the frosting slices cleanly.
- Instant pistachio pudding mix — Thickens into a fluffy, spoonable frosting with true pistachio flavor.
- Whipped topping (thawed) — Lightens everything for a billowy finish that holds its shape.
- Chopped pistachios (optional) — Crunchy, salty-sweet garnish for color and texture.
How to Make This Pineapple Pistachio Cake
STEP 1: Heat the oven to 350°F (175°C). Lightly coat a 9×13-inch metal baking pan with cooking spray. Set a cooling rack nearby so the hot cake has a place to rest later.
STEP 2: In a large bowl (or stand mixer), combine the dry cake mix and pistachio pudding mix. Stir in the oil, eggs, and the entire can of crushed pineapple, including juices, until the batter looks smooth and glossy.
STEP 3: Beat on medium to medium-high speed for about 2 minutes to fully hydrate the mixes and aerate the batter slightly. Scrape the sides and bottom once so no dry pockets hide.
STEP 4: Pour the batter into the prepared pan and spread it into an even layer. Tap the pan gently on the counter to pop any large bubbles so the crumb bakes tight and tender.
STEP 5: Bake 35–40 minutes, until the top is lightly golden and a toothpick inserted in the center comes out clean or with a few moist crumbs. Rotate the pan once if your oven has hot spots.
STEP 6: Transfer the pan to a rack and cool completely. A fully cooled cake prevents the frosting from melting and guarantees clean slices.
STEP 7: For the frosting, whisk half-and-half, heavy cream, and pistachio pudding mix in a bowl for 1–2 minutes until thick and smooth. Let stand 5 minutes; it will continue to firm.
STEP 8: Fold in the thawed whipped topping until no streaks remain. Spread the frosting over the cooled cake, sprinkle with chopped pistachios if using, cover, and refrigerate 4–6 hours (or overnight) for the best set and flavor.
Pro Tips for Pineapple Pistachio Cake
- Mind the moisture: Don’t drain the pineapple; its juices are part of the liquid balance and create that ultra-moist crumb.
- Chill for clean cuts: A good chill lets the frosting firm and the cake flavors meld. Use a warm, dry knife and wipe between slices.
- Metal beats glass: A light-colored metal pan promotes even rise and truer bake times; glass can run hot and brown the edges faster.
Serving Ideas for Pineapple Pistachio Cake
- Tropical plate: Add fresh pineapple spears or kiwi for brightness and a temperature contrast against the cool, creamy frosting.
- Coffee companion: Serve with lightly sweetened iced coffee or espresso—bitterness balances the cake’s gentle sweetness.
- Crunch factor: Garnish each slice with extra chopped pistachios or toasted coconut for texture and a pretty finish.
Can I use white or vanilla cake mix instead?
Yes—white or vanilla cake mix both work. Expect a slightly lighter color and flavor. Keep the rest of the ingredients and method the same, and monitor bake time for doneness near the 35-minute mark.
Can I swap the milks in the frosting?
You can use all heavy cream for extra richness or all half-and-half for a lighter bite. Using both gives the best balance of body, sliceability, and a billowy, mousse-like texture.
How do I avoid a gummy center?
Bake until a tester comes out with just a few moist crumbs, cool completely before frosting, and chill well. Also mix the batter thoroughly for 2 minutes so the pudding hydrates and bakes evenly.
Can I make cupcakes instead?
Absolutely. Divide batter among lined muffin cups, filling about ¾ full, and bake at 350°F for roughly 18–22 minutes. Frost once completely cool and chill to set the fluffy pistachio topping before transporting.
Is the cake very sweet?
It’s pleasantly sweet with tropical notes. For a softer sweetness, garnish with unsweetened toasted coconut, or add a pinch of sea salt to the pistachios on top to create balance without altering the base recipe.
How to Store & Reheat
This cake is happiest cold. Cover the pan and refrigerate for 4–5 days; the crumb stays moist and the frosting remains fluffy. To freeze, wrap the unfrosted cake tightly for up to 2 months, then thaw overnight and frost fresh. You can also freeze frosted slices on a sheet pan until firm, then wrap individually for up to 1 month—thaw in the fridge. There’s no reheating needed; serve chilled or let slices stand 10–15 minutes at room temperature for a softer frosting. If condensation forms after chilling, gently blot before adding a final sprinkle of pistachios so the top stays pretty.
This Pineapple Pistachio Cake gives you the best of both worlds: the ease of a mix and the flavor of something made with care. The pudding keeps everything cushiony, the pineapple brings sunny moisture, and that green-tinted frosting seals the deal. Once it’s chilled and sliced, don’t be surprised when the platter empties—there’s a reason this one earns repeat requests.
Pineapple Pistachio Cake with Pistachio Frosting

Instructions
- Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch rectangular baking dish with non-stick spray.
- In a large bowl or the bowl of a stand mixer, combine the yellow cake mix, pistachio pudding powder, eggs, crushed pineapple (with juice), and oil.

Prepare the Frosting
- In a mixing bowl, whisk together the half-and-half, heavy cream, and pistachio pudding mix until smooth and thickened, about 1 to 2 minutes. Let it stand for 5 minutes to set further.
- Gently fold in the thawed whipped topping until evenly incorporated into the pudding mixture.
- Once the cake has cooled completely, spread the pistachio frosting evenly over the surface.
- If desired, sprinkle finely chopped pistachios across the top for garnish.
- Cover the cake with foil or a fitted lid and refrigerate for 4 to 6 hours, or overnight for enhanced flavor and texture.
