Ready in minutes and always a crowd favorite, this retro green dessert has been passed down for generations—and for good reason!

 Ingredients

• 1 package (3.4 ounces) instant pistachio pudding mix
  This gives the dessert its signature pale green color and nutty flavor.
• 1 can (20 ounces) crushed pineapple, undrained
  Adds natural sweetness and a juicy texture.
• 1 cup miniature marshmallows
  For soft, pillowy bites in every spoonful.
• ½ cup chopped pecans or walnuts (optional)
  Adds crunch and a toasted, nutty flavor.
• 1 tub (8 ounces) whipped topping (like Cool Whip), thawed
  Makes the fluff irresistibly light and creamy.
• Maraschino cherries, for garnish (optional)
  A sweet and colorful finishing touch.

 Instructions

Step 1: Combine Pudding & Pineapple

In a large mixing bowl, stir together the instant pistachio pudding mix and the undrained crushed pineapple. Mix until the pudding powder is fully dissolved and the mixture starts to thicken slightly. The juice from the pineapple acts as the liquid that activates the pudding mix—no milk needed!

Step 2: Fold in Marshmallows & Nuts

Next, add the miniature marshmallows and chopped nuts (if using). Gently fold everything together until the ingredients are evenly distributed. The marshmallows will soften slightly as the salad chills, giving the dessert its signature fluffy texture.

Step 3: Add the Whipped Topping

Carefully fold in the thawed whipped topping. Do this gently to keep the mixture light and airy. Mix just until no streaks remain and everything is well incorporated.

Step 4: Chill to Set

Cover the bowl with plastic wrap or a lid and place it in the refrigerator for at least 1 hour. This allows the flavors to meld, the marshmallows to soften, and the texture to firm up into the perfect fluff consistency.

Step 5: Serve & Garnish

Before serving, give the fluff a gentle stir. Spoon into individual dessert cups, a large trifle bowl, or serve it family-style. For a festive touch, top each portion with a maraschino cherry.

 Tips & Variations

• Add coconut: Mix in ½ cup of shredded sweetened coconut for a tropical twist.
• Make it a dessert dip: Serve with vanilla wafers, graham crackers, or shortbread cookies for dipping.
• Use different pudding flavors: While pistachio is classic, you can also try this with vanilla, banana cream, or cheesecake pudding for fun variations.
• Lighten it up: Use sugar-free pudding and light whipped topping for a lower-calorie version.
• Holiday ready: Add red and green maraschino cherries during the holidays for a festive look!

 Storage

• Refrigerator: Store leftovers in an airtight container in the fridge for up to 3–4 days. The texture may become softer over time as the marshmallows melt into the mix.
• Make Ahead: Pistachio fluff is even better when made a day ahead—just be sure to stir gently before serving.
