Ingredients You’ll Need
This recipe is flexible, but the classic version includes:
- 1 box (3.4 oz) instant pistachio pudding mix
- 1 can (20 oz) crushed pineapple (with juice)
- 1 tub (8 oz) whipped topping, thawed (or homemade whipped cream)
- Optional: 1 cup mini marshmallows
- Optional: 1/2 cup chopped pecans or walnuts
- Optional: 1/2 cup shredded coconut
- Optional: maraschino cherries for garnish
Important note: Use instant pudding mix, not cook-and-serve. Instant pudding thickens properly without heating.
How to Make Pistachio Pineapple Fluff
- Mix pineapple and pudding: In a large bowl, pour the crushed pineapple (do not drain) and add the pistachio pudding mix. Stir until fully combined. It will start thickening quickly.
- Fold in whipped topping: Gently fold in whipped topping until the mixture becomes smooth and fluffy.
- Add mix-ins (optional): Stir in mini marshmallows, nuts, or coconut if you want extra texture.
- Chill: Cover and refrigerate for at least 1–2 hours to let it set and develop the best flavor.
- Serve: Spoon into bowls or a dessert tray. Garnish with cherries, pineapple pieces, or crushed nuts if desired.
Tips for the Best Fluff Texture
- Don’t drain the pineapple. The juice helps activate and thicken the pudding mix.
- Fold, don’t stir aggressively. Folding keeps the texture airy and light.
- Chill before serving. The flavor improves and the fluff becomes thicker after resting.
- Use thawed whipped topping. If it’s frozen, it won’t mix smoothly and can turn watery as it melts.

It’s also fun served as a “dessert dip” with vanilla wafers, shortbread cookies, or graham crackers.
Storage and Make-Ahead
- Refrigerator: Store in an airtight container for up to 3 days.

- Not freezer-friendly: Freezing can separate the whipped topping and change the texture.
If you add bananas, add them right before serving because they brown quickly.
FAQ
Can I use fresh pineapple instead of canned?
Fresh pineapple contains enzymes that can affect how some creamy desserts set. For best results, use canned crushed pineapple (or briefly cook fresh pineapple first).
Why is my fluff runny?
This can happen if the whipped topping wasn’t fully thawed, the mix wasn’t chilled long enough, or if extra liquid-heavy fruit was added. Chill longer and avoid adding fruit with lots of juice.
Can I make it without whipped topping?
Yes. You can use homemade whipped cream, but it may not hold as long as whipped topping. If using homemade, serve within 24 hours for best texture.
