Gather all the ingredients for your Cherry Fluff: cherry pie filling, drained crushed pineapple, miniature marshmallows, shredded coconut, chopped nuts, sour cream, and optional whipped topping.

In a large mixing bowl, combine the cherry pie filling with the well-drained crushed pineapple and stir gently.

Add the miniature marshmallows to the cherry and pineapple mixture and fold them in gently.

Pour in the sweetened shredded coconut and fold it into the mixture.

Incorporate the chopped pecans or walnuts into the bowl.

Gently fold in the sour cream until everything is combined.

Taste the mixture and adjust the sweetness according to your preference.

Transfer the Cherry Fluff into a serving dish, smoothing the top.

Optionally swirl whipped topping on top of your Cherry Fluff.

Cover the dish with plastic wrap and refrigerate for at least 2 hours before serving.
