Gather all your ingredients: cherry pie filling, crushed pineapple, miniature marshmallows, shredded coconut, chopped pecans or walnuts, sour cream, and optional whipped topping.

In a spacious mixing bowl, pour in the cherry pie filling and the drained crushed pineapple. Stir gently until fully combined.

Add in the miniature marshmallows and fold them into the fruit mixture, ensuring it's evenly distributed.

Introduce the shredded coconut into the bowl and fold gently, preserving the fluffy texture.

Add the chopped nuts and fold them into the mixture, ensuring even distribution.

Fold in the sour cream until everything is well combined and the fluff takes on a creamy texture.

Taste the mixture and adjust sweetness if needed with sugar or whipped cream.

Transfer your mixture into a festive serving dish or trifle bowl and smooth the top.

Dollop whipped topping on the surface for a finishing touch, if desired.

Cover with plastic wrap and refrigerate for at least 2 hours to allow flavors to meld.
