Put all of the ingredients into the Ninja Creami pint container.
Give it a really good mix to combine it all evenly.
Put the lid on the container freeze for 24 hours.
Remove the lid and put the frozen tub into the outer bowl and put on the outer bowl lid. Put into the Creami machine and set to the Frozen Yogurt setting and spin.This may result in a crumbly texture.
Replace the tub in the machine and press Respin. This may take 1-2 more re-spins to achieve the perfect creamy consistancy.
Notes
We used fat free Greek yogurt, to keep this a low in fat dessert. However, if you wanted it extra creamy, then full fat yogurt would be best.
Some recipes might say that if you are using fat free, then you need to add some heavy cream to it to increase the fat content and make it creamier. However, we didn't find that it made that much of a difference to the creaminess, so I wouldn't bother.
Another great mix-in is crushed Oreos, as it gives it a cookies and cream flavor.
To combine everything together easier, you can use a milk frother or use a blender to blend everything first.
When putting the ingredients into the pint container, don't exceed the max fill line.
