Call it Orange Fluff, Dreamsicle, or Creamsicle Salad, this Mandarin Orange Salad is a classic side dish that's irresistibly cool, creamy, and sweet. It's always a hit at summertime parties and picnics!
Set out a large mixing bowl. Pour the orange Jell-O mixture into the bowl. Then stir in 1 cup of boiling water. Stir until the Jell-O granules have fully dissolved. Then pour in ½ cup of cold water and mix well. Place the bowl in the refrigerator for at least 20 minutes to bring the temperature of the Jell-O down.
Meanwhile drain the mandarin orange and crushed pineapple cans. Measure out the remaining ingredients.
Once the Jell-O mixture has cooled to room temperature, or just slightly warmer than room temperature, whisk in the instant vanilla pudding mix. Whisk well until the mixture is fully smooth. Then place the bowl back in the refrigerator for 15-30 minutes longer, until the mixture has thickened into a thick pudding base. *It’s important that the mixture does not stay in the fridge too long, because you do not want the gelatin to solidify the mixture. If the mixture gets too thick, you will need to warm it in the microwave and then cool it off again. Check it for the next 15-30 minutes to make sure it is just the consistency of thick pudding.
Fold the Cool Whip into the orange pudding base. One smooth, mix in the drained mandarin orange slices, crushed pineapple, and mini marshmallows. Stir until just combined. Then cover and refrigerate for at least one hour.
