To use an ice cream maker, ensure the bowl has been frozen for at least 24 hours. Combine the cottage cheese, maple syrup, and vanilla extract in a high-speed blender. Secure the lid and blend for at least 60 seconds, or until it's very smooth with no chunks of cottage cheese remaining.
Pour the mixture into the bowl of your ice cream maker and process for 20 to 25 minutes, or until it has a soft-serve consistency. Serve right away, or transfer the mixture to a loaf pan and freeze for one more hour. (This will make it slightly firmer and more scoopable; if you freeze it overnight, the ice cream will become icy and hard.)
Leftover ice cream can be stored in an airtight container in the freezer for up to 3 months, but it will not be as easy to scoop as it is when you first make it. (See the photos in the post.) Its icy texture turns into more of a "creamy shaved ice," which is also delicious, but it will need to be scraped out of the pan, rather than scooped.
Notes
Nutrition information is for roughly 1/2 cup of ice cream, or a quarter of this batch. This information is automatically calculated using generic ingredients, so it's just an estimate and not a guarantee.No ice cream maker? Pour the mixture into a loaf pan and freeze (covered) for 6 to 8 hours. In this case, it will have a hard, icy texture and will likely be served more as a creamy shaved ice consistency. My kids love this but prepare for an icy result rather than a scoopable one. Let it rest on the counter for up to 30 minutes if you find it difficult to remove from the pan.
