Pour the protein shake, Jello mix, mandarin oranges, and vanilla bean paste into a small blender and mix until all of the ingredients have been mixed together well. If you don't blend it long enough, the Jello mix will remain clumpy. Once fully mixed, pour into a Ninja Creami pint container.
Freeze on a level surface for 24 hours. Your freezer should be between 9 and -7 degrees Fahrenheit. To avoid getting a bump on the top of the frozen mixture, freeze with the lid off of the container.
Process the Ice Cream
After 24 hours, remove the pint container from the freezer.
Place the pint container into the outer bowl of the Ninja Creami and then process on "LITE ICE CREAM."
If the ice cream is dry or crumbly looking (like sand), pour in a tablespoon or two of unsweetened almond milk and then re-spin. If the ice cream looks like little balls of ice cream, respin without adding liquid. You may have to repeat this process a couple of times.
Remove the pint from the machine and enjoy!
Notes
What do I do with the bump in the ice cream after it's been frozen?This is a very controversial topic. Some ALWAYS shave down the bump before processing the ice cream. You can use a warm spoon, or microwave the pint to soften it a little bit enough to flatten it. Many freeze the containers without the lids to help reduce the likelihood that the bump will appear. I personally have had no issues with the bump and have processed hundreds of pints. The bump is different from an unlevel pint. You should never process an unlevel pint (usually from freezing on an unlevel surface).
What brand of protein shake is the best?There is no solid answer on this. It depends on your own preferences. What tastes good to one person may not taste good to someone else. A couple of popular brands are the Fairlife Protein Shakes and the Premier Protein Shakes. These two brands are said to be the smoothest in texture and best tasting. But, you will need to sample different brands to find what you like the best.
