This retro Orange Fluff dessert mixes orange gelatin, mandarin oranges, marshmallows, and Cool Whip into a creamy, citrusy salad that tastes like a creamsicle. It’s no-bake, make-ahead friendly, and perfect for potlucks or holidays.
For best texture, drain fruit thoroughly and avoid overmixing. Use instant pudding, not cook-and-serve. Chill at least 2 hours before serving. Store covered in the refrigerator for up to 3 days; do not freeze. Stir gently before serving if slight separation occurs. Variations: add coconut and cherries for an ambrosia twist, use French vanilla pudding with orange zest for a creamsicle vibe, or swap fruits like mango or berries (pat fresh fruit dry).
