Ingredients
2 (3.4 oz) boxes instant pistachio pudding mix
2 cups cold milk
1 cup whipped topping, thawed
1 cup mini marshmallows
¾ cup chopped pecans, lightly toasted
½ cup crushed pineapple, well drained
½ teaspoon vanilla extract
Pinch of salt
Instructions
In a large mixing bowl, whisk together the pistachio pudding mix and cold milk for about 2 minutes until thickened.
Let the pudding sit for 2 to 3 minutes to fully set before adding other ingredients.
Gently fold in the vanilla extract and a small pinch of salt.
Add the crushed pineapple and fold until evenly distributed.
Fold in the whipped topping carefully to keep the mixture light and fluffy.
Stir in the mini marshmallows, mixing gently so they do not deflate the fluff.
Add the chopped pecans and fold just until combined.
Taste and adjust sweetness if needed by adding a spoon of whipped topping.
Cover the bowl and refrigerate for at least 1 hour to allow flavors to meld.
Stir lightly before serving and garnish with extra pecans if desired.
Tips
Use instant pudding only, not cook-and-serve, for proper texture.
Cold milk helps the pudding set quickly and smoothly.
Drain pineapple very well to prevent a watery fluff.
Toast pecans lightly to enhance their flavor.
Fold gently to keep the mixture airy.
Chill before serving for the best consistency.
Add marshmallows last to keep them soft and fluffy.
Use full-fat milk for a richer texture.
Serve in a chilled bowl for extra freshness.
Keep covered tightly to avoid absorbing fridge odors.
Variations
Replace pecans with chopped walnuts or almonds.
Add shredded coconut for extra texture.
Use sugar-free pudding mix for a lighter option.
Fold in white chocolate chips for sweetness.
Add crushed graham crackers for a cheesecake-style twist.
Use homemade whipped cream instead of whipped topping.
Add a drop of almond extract for deeper nut flavor.
Mix in sliced bananas just before serving.
Layer the fluff in dessert cups for presentation.
Turn it into a pie filling using a graham crust.
