The Ingredients

This recipe uses simple, affordable ingredients that come together beautifully.

1 box orange Jell-O – For the bright, citrusy base.
1 box instant vanilla cheesecake pudding mix – For creaminess and tang.
1 cup boiling water – To dissolve the Jell-O.
½ cup cold water – To cool and set the Jell-O.
8 ounces Cool Whip, thawed – For lightness and creaminess.
1 small can mandarin oranges, drained very well – For juicy citrus pops.
1 cup pastel-colored miniature marshmallows – For pillowy sweetness.
Optional Garnish: Extra mandarin oranges, a few mini marshmallows, and 1-2 fresh mint leaves.

Step-by-Step Instructions

Step 1: Dissolve the Gelatin

In a large mixing bowl, add the boiling water and the orange-flavored Jell-O. Whisk vigorously until the gelatin powder is completely dissolved.

Pro Tip: Make sure the water is boiling hot—it’s essential for dissolving the gelatin completely.

Step 2: First Chill

Pour the cold water into the bowl and stir. Place the bowl in the refrigerator and chill for 20 minutes, or until the mixture has visibly thickened.

Pro Tip: Don’t skip this step—the mixture needs to thicken before adding the pudding mix.

Step 3: Incorporate the Pudding

Remove the bowl from the fridge. Add the dry instant vanilla cheesecake pudding mix and whisk until smooth and combined. Return the bowl to the refrigerator and chill for another 20 minutes until it thickens further.

Pro Tip: Use the dry pudding mix, not prepared pudding.

Step 4: Fold in the Goodies

To the thickened mixture, add the Cool Whip, drained mandarin oranges, and miniature marshmallows. Using a rubber spatula, gently fold everything together until well mixed. (Do not stir vigorously, or the fluff will deflate!)

Pro Tip: Fold gently! You want to keep the fluff light and airy, not dense and deflated.

Step 5: Final Chill

Cover the bowl and chill in the refrigerator for 1 to 2 hours to let the flavors meld and the marshmallows soften.

Pro Tip: The longer it chills, the better the flavors meld.

Step 6: Serve and Enjoy

When ready to serve, scoop into individual bowls and garnish with extra oranges, marshmallows, and mint leaves if desired. Enjoy!

Pro Tip: Serve cold for the best texture and flavor.
