Add the yogurt, milk and crumbled cake to the Ninja Creami pint container.
Give everything a good mix. It is fine if the cake is still a bit lumpy.
Put the lid onto the pint container and 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 Ninja Creami machine and set to the frozen Yogurt setting and spin. This may result in a crumbly consistency.
Replace the tub in the machine and press Re-spin. This may take 1-2 more re-spins to achieve the perfect creamy consistency.
Notes
If you wanted to make this a little extra creamy, without using full fat cottage cheese, yogurt and milk, then just add a couple of tablespoons of heavy cream (double cream) to the mixture.
This is a fairly runny ice cream, as we didn't want to add anything like pudding mix that I see in so many Creami recipes. So, just keep that in mind that you will need to serve it quickly, or it can go back in the freezer to harden up.
When putting the ingredients into the pint container, don't exceed the max fill line.
The nutritional information will vary depending on what cake you have used. We have used the amount for a small slice of chocolate cake with chocolate frosting.
