In a blender or food processor, combine the cottage cheese, peanut butter, honey (or maple syrup), vanilla extract, and milk. Blend until smooth and creamy.
Taste the mixture and adjust sweetness if necessary by adding more honey or maple syrup.
If using, fold in the chocolate chips gently with a spatula.
Pour the mixture into a freezer-safe container and spread it evenly.
Cover the container with a lid or plastic wrap and freeze for at least 4 hours, or until firm.
Before serving, let the ice cream sit at room temperature for about 5-10 minutes to soften slightly for easier scooping.
