1-First, stir the instant vanilla pudding mix and the entire can of crushed pineapple with juice in a large bowl until fully combined. This step is vital as the juice helps the pudding set correctly, avoiding any runny results. Once mixed, you’ll notice the mixture starting to thicken nicely.

2-Next, gently fold in the thawed whipped topping, mini marshmallows, coconut, and pecans just until blended. Be careful not to overmix, as this keeps the fluff light and airy. For dietary tweaks, substitutes like plant-based whipped topping work well here.

3-Finally, cover the mixture with plastic wrap and refrigerate for a few hours to let it set. This allows the flavors to blend, making your Pineapple Fluff even more delicious. The whole process is quick, serving about 10 people with minimal effort.
