Prepare the Soda: Gently pour the orange soda into a large mixing bowl or liquid measuring cup. Using a spoon, stir it consistently for about 4-5 minutes. This simple step helps to release some of the carbonation, making your soda semi-flat and ready for freezing.
Mix it Up: Add the entire packet of Dream Whip mix directly into the semi-flat soda. Stir thoroughly until both ingredients are completely combined. Don't worry if it fizzes a bit; that's part of the process! If you see excessive foam, feel free to gently skim some off the top.
Freeze Overnight: Carefully pour your mixture into a Ninja Creami pint container. Place the lid loosely on top (you can even leave it slightly ajar) to allow any remaining gas to escape while freezing. Transfer the pint to your freezer and ensure it sits on a level surface for at least 24 hours, or until it's completely solid.
Creami Time!: Once your mixture is rock-solid, remove the pint from the freezer and take off its lid. Place the pint into the Ninja Creami's outer bowl, secure the outer bowl lid, and then lock the entire assembly into the Ninja Creami machine. Select the "Lite Ice Cream" button and let the machine work its magic.
Achieve Perfect Consistency: After the first cycle, check the texture of your ice cream. If it appears a little crumbly or powdery, simply add one tablespoon of water (or a tiny splash of extra orange soda) back into the pint, then use the "Re-spin" button. This will help create a wonderfully smooth and creamy finish, ready for you to enjoy!
