Pour the unsweetened almond milk, protein powder, sugar substitute, coconut extract, and gaur gum into a small blender and blend until all ingredients are fully combined. Pour the mixture 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, pour in a tablespoon or two of leftover pineapple juice from the canned pineapples and then re-spin. You may have to repeat this process a couple of times. Keep in mind that the pineapple mix in has a high moisture content so it will change the consistency of the ice cream. Adding too much pineapple juice on a re-spin will make the consistency of the ice cream much softer.
Dig a well down the center of the ice cream and pour in the crushed pineapple. Process on mix-ins.
Remove the pint from the machine and enjoy!

Notes
Can rum be added to this recipe to make it a real pina colada?Yes, you can add rum or any other liquor that you would like.But, alcohol does not freeze like the other ingredients do.So, adding alcohol has a tendency to provide a softer ice cream.Usually about an ounce of alcohol will work in the base recipe without negatively impacting the texture too much.The more alcohol you add, the less likely it is that the base will freeze solid.If you want more alcohol, try adding it during the re-spin process.Can fresh pineapple be used instead of canned?Yes, but be sure that the pineapple is sweet before adding it to the recipe.If the pineapple is not sweet, the final product won't be very sweet and will be lacking pineapple flavor.Be sure to cut the pineapple up into very small pieces so that it gets distributed throughout the entire container of ice cream.The juicier the pineapple, the less likely you will need to do a re-spin or add any additional liquid.
