Add the 16 ounces of cottage cheese, ¼ cup maple syrup, and 1½ teaspoons vanilla extract to a blender. Process for 45 seconds, or until the ingredients begin to form a smooth, creamy mixture.
Stop the blender and scrape down the sides if necessary. Blend for another 15 seconds, ensuring that no visible cottage cheese curds remain.
Pour the fully blended mixture into a freezer-safe container and spread it evenly.
Place the container in the freezer for 3 to 4 hours, or until the ice cream reaches the preferred consistency. Stir the mixture thoroughly once every hour during the freezing period to encourage a smoother texture.
