This dreamy Creamsicle Orange Fluff perfectly captures the nostalgic flavor of those orange and vanilla ice cream pops we all loved as children, transformed into a cloud-like dessert that's perfect for gatherings. With its vibrant orange hue studded with juicy mandarin oranges and pastel mini marshmallows, this dessert is as visually appealing as it is delicious. I've been making this family favorite for years, and it never fails to transport everyone back to carefree summer days with just one spoonful.
The first time I brought this to our neighborhood block party, three different people asked for the recipe before the evening was over! There's something magical about the combination of cool, citrusy flavor and pillowy texture that makes this dessert impossible to resist, even after a hearty meal.
Ingredients
- 1 box (3 oz) orange Jell-O: Creates that distinctive orange flavor and vibrant color that makes this dessert so appealing.
- 1 box (3.4 oz) instant vanilla cheesecake pudding mix: Adds creamy vanilla notes and helps create the fluffy texture. Regular vanilla pudding works too, but the cheesecake variety adds a wonderful tang.
- 1 cup boiling water: Needed to dissolve the Jell-O properly.
- 1/2 cup cold water: Helps cool the mixture and achieve the right consistency.
- 8 oz Cool Whip, thawed: The key to the light, fluffy texture. Make sure it's completely thawed for easy folding.
- 1 small can (11 oz) mandarin oranges, drained: Provides bursts of juicy citrus flavor and pretty orange segments throughout the fluff.
- 1 cup pastel-colored miniature marshmallows: Adds fun pops of color and a delightful chewy texture that contrasts with the smooth fluff.

Step-by-Step Instructions
- Step 1:
- Dissolve the Jell-O - Start by bringing 1 cup of water to a full boil either in a kettle or on the stovetop. Pour the boiling water into a large mixing bowl, then add the orange Jell-O powder. Whisk vigorously for about 2 minutes until the powder is completely dissolved. Check the bottom of the bowl to ensure no granules remain.
- Step 2:
- Add cold water and begin chilling - Pour 1/2 cup of cold water into the dissolved Jell-O mixture and stir to combine. This helps cool the mixture and creates the right consistency. Place the bowl in the refrigerator for approximately 20 minutes, or until the mixture starts to thicken slightly. You're looking for a partially set consistency—it should be thickened but not fully set or solid.
- Step 3:
- Incorporate the pudding mix - Remove the slightly thickened Jell-O from the refrigerator. Sprinkle the instant vanilla cheesecake pudding mix over the surface, then whisk immediately and thoroughly until fully incorporated. The mixture will become noticeably thicker and creamier. Return the bowl to the refrigerator for another 20 minutes to allow further thickening.
- Step 4:
- Fold in the Cool Whip - After the second chilling period, take the bowl out again. The mixture should now be quite thick. Gently fold in the thawed Cool Whip using a rubber spatula with a light hand. Start at the bottom of the bowl and lift the mixture over itself, turning the bowl as you go. Continue until the mixture is uniform in color and completely smooth, with no streaks of white remaining.
- Step 5:
- Add oranges and marshmallows - Carefully fold in the drained mandarin orange segments and the pastel mini marshmallows. Use a gentle touch to prevent breaking the orange segments or deflating the fluffy mixture. Distribute them evenly throughout the fluff.
- Step 6:
- Final chilling - Cover the bowl with plastic wrap and return it to the refrigerator. Allow the Creamsicle Orange Fluff to chill for at least 1-2 hours, though overnight is even better. This resting time allows the flavors to meld together and the dessert to set to the perfect consistency.
- Step 7:
- Serve with flair - When ready to serve, give the fluff a gentle stir if needed. Scoop into individual serving dishes or present in a clear glass bowl to showcase the beautiful orange color and colorful marshmallows. For an extra special touch, garnish with additional mandarin orange segments, a few extra marshmallows, or even a small sprig of mint.
The Secret to Perfect Fluff Texture
The key to achieving that perfect cloud-like texture lies in the proper chilling times between steps. Don't rush the process by trying to add everything at once. The initial chilling allows the Jell-O to partially set, which is crucial for the overall structure. Similarly, adding the pudding mix and chilling again creates layers of thickening that result in the ideal fluffy consistency once the Cool Whip is folded in.
Make It Your Own
This versatile recipe welcomes creative variations:
- Use different Jell-O flavors like strawberry or lime for a completely different flavor profile
- Substitute the mandarin oranges with other fruits like pineapple chunks or sliced strawberries
- Add a cup of cottage cheese for extra creaminess and protein
- Include chopped nuts like pecans or walnuts for a delightful crunch
- Sprinkle with toasted coconut for a tropical twist
- Create a layered parfait by alternating the fluff with graham cracker crumbs
Perfect for Any Occasion
This Creamsicle Orange Fluff is perfect for:
- Summer picnics and barbecues
- Holiday gatherings (especially Easter with its pastel colors)
- Baby or bridal showers
- Potluck dinners

I learned through trial and error that the order of ingredients truly matters! My first attempt at this recipe involved adding the Cool Whip too early, resulting in a runny consistency that never quite set properly. Following these specific steps ensures the perfect fluffy texture every time.

After making this countless times, I've discovered that letting the final dessert chill overnight results in the absolute best flavor and texture. The extra hours allow the marshmallows to soften slightly and the flavors to fully meld together, creating a more cohesive and delicious dessert experience.
This Creamsicle Orange Fluff has become my signature potluck contribution—the dish everyone expects me to bring and is disappointed if I don't! It's one of those magical recipes that manages to be simultaneously nostalgic and fresh, simple yet impressive. Whether you're making it for a special occasion or just because you're craving something sweet and refreshing, this fluffy orange dessert is sure to become a favorite in your recipe collection too.
