Why You Will Completely Fall in Love with This Recipe
There is a reason this cake has been making the rounds at family reunions and church picnics for decades. First and foremost, it is unbelievably moist. The secret? We are using an entire can of crushed pineapple—juices and all. The natural fruit juices soak into the batter, ensuring every single bite is tender and packed with flavor.
Secondly, it uses a brilliant shortcut: boxed angel food cake mix. Angel food cake is known for its light, airy texture, which perfectly balances the richness of the pistachio pudding mix and the density of the pineapple. When these ingredients bake together, they create a unique texture that is somewhere between a classic sponge cake and a rich, pudding-infused poke cake.
Finally, the frosting is out of this world. It is ridiculously simple, utilizing creamy whipped topping and another box of instant pistachio pudding. It is light, not overly sweet, and acts as the perfect cloud-like topping for the fruity cake beneath it.
What You Need: The Ultimate Ingredient Breakdown
One of the best ways to ensure your baking is a success is to understand your ingredients. Here is exactly what you will need for this easy pistachio pineapple cake:
For the Cake:
- Angel Food Cake Mix (1 box): Do not follow the instructions on the back of the box! We are simply using the dry mix as our base. It provides a beautifully airy structure.
- Instant Pistachio Pudding Mix (one 3.4 oz box): Make sure you grab the instant pudding, not the cook-and-serve variety. This gives the cake its gorgeous pastel green color and subtle nutty flavor.
- Vegetable Oil (½ cup): Oil keeps the cake incredibly moist for days, much longer than butter would.
- Eggs (3 large): These bind the ingredients together and provide structure to the cake crumb. Use room-temperature eggs for the best blending.
- Crushed Pineapple (one 20 oz can): The star of the show! Do not drain the can. The pineapple juices act as the primary liquid in this batter, adding sweetness, moisture, and that signature tropical tang.
For the Luscious Frosting:
- Cool Whip (8 oz tub): Make sure it is fully thawed in the refrigerator before you begin. It gives the frosting a stable, fluffy texture.
- Whole Milk (⅔ cup): Cold milk works best to activate the instant pudding mix.
- Instant Pistachio Pudding Mix (one 3.4 oz box): The second box of pudding mix flavors and thickens our frosting.
- Chopped Pistachios: An optional but highly recommended garnish for a delightful, salty crunch.
Expert Tips for Recipe Success
- Toast Your Nuts: If you want to elevate this simple dessert, lightly toast the chopped pistachios in a dry skillet over medium heat for 3-4 minutes before using them as a garnish. It brings out their natural oils and deepens the flavor.
- Do Not Drain the Pineapple: I cannot stress this enough. If you drain the pineapple, your cake will be dry and crumbly. Those juices are absolutely essential!
- Patience is Key: The 2-hour chilling time isn’t just a suggestion. It gives the pudding in the frosting time to set up fully, making the cake much easier to slice and enhancing the overall flavor profile.
How to Store and Freeze Your Pistachio Pineapple Cake
Because of the dairy and pudding in the frosting, this cake must be kept refrigerated.
- In the Fridge: Cover the 9×13 pan tightly with plastic wrap or a fitted lid. The cake will stay moist and delicious in the refrigerator for up to 4 to 5 days.
- In the Freezer: If you want to freeze the cake, I highly recommend freezing the baked, unfrosted cake base. Wrap it tightly in plastic wrap and aluminum foil, and freeze it for up to 3 months. Thaw it overnight in the fridge, then make the frosting fresh on the day you plan to serve it. Freezing the Cool Whip frosting can sometimes alter its fluffy texture once thawed.
Frequently Asked Questions (FAQs)
Can I use a regular white or yellow cake mix instead of an angel food cake mix? Yes, you absolutely can! However, the texture will be slightly different. Angel food cake mix yields a lighter, fluffier crumb, while a white or yellow cake mix will result in a denser, more traditional cake texture. Both are absolutely delicious.
Can I substitute the Cool Whip with homemade whipped cream? You can, but proceed with caution. Cool Whip contains stabilizers that keep the frosting thick and prevent it from weeping over time. If you use homemade whipped cream, be sure to whip it to stiff peaks, and consider stabilizing it with a little bit of unflavored gelatin or cream cheese to ensure it holds up in the fridge.
Can I use crushed fresh pineapple? Canned crushed pineapple is strongly recommended for this recipe because of the specific ratio of fruit to juice. Fresh pineapple contains an enzyme called bromelain, which can sometimes interfere with how the cake and pudding set up, so stick to canned for the best, most consistent results!

- For the Cake:
- 1 box 16 oz Angel Food Cake mix (dry mix only)
- 1 box 3.4 oz Instant Pistachio Pudding mix
- ½ cup vegetable oil
- 3 large eggs
- 1 can 20 oz crushed pineapple, with juices (do not drain)
- For the Frosting:
- 1 box 3.4 oz Instant Pistachio Pudding mix
- ⅔ cup whole milk cold
- 1 tub 8 oz Cool Whip, thawed
- Chopped pistachios for decoration
Instructions
- Preheat & Prep: Preheat your oven to 350°F (175°C). Generously grease a 9×13-inch baking dish with non-stick cooking spray.
- Mix the Cake Batter: In a large mixing bowl, combine the dry angel food cake mix, dry pistachio pudding mix, vegetable oil, eggs, and the entire can of crushed pineapple (including the juices). Beat with a hand mixer on medium speed until the ingredients are well combined and the batter is smooth.
- Bake: Pour the batter into your prepared baking dish, spreading it out evenly. Bake for 30 to 35 minutes, or until a toothpick inserted into the center of the cake comes out clean.
- Cool: Remove the cake from the oven and allow it to cool completely in the pan on a wire rack. (Do not attempt to frost a warm cake!)
- Prepare the Frosting: While the cake is cooling, make the frosting. In a medium bowl, whisk together the second box of instant pistachio pudding mix and the cold milk until the mixture begins to thicken.
- Fold & Combine: Gently fold the thawed Cool Whip into the pudding mixture until fully combined and fluffy.
- Frost & Chill: Spread the frosting evenly over the completely cooled cake. Place the cake in the refrigerator to chill for at least 2 hours before serving to allow the frosting to set.
- Garnish & Serve: Right before slicing, sprinkle the top of the cake with chopped pistachios. Enjoy!
