Orange Fluff is a creamy dessert made with orange Jello, Cool Whip, vanilla pudding, and mandarin oranges. This fluff recipe mixes up in one bowl and chills quickly, making it one of the easiest dessert recipes to prep ahead. Mini marshmallows add a soft texture, and the citrus flavor makes it ideal for warm-weather gatherings. Great as a Cool Whip mandarin orange salad or a light, refreshing dessert.
