Yes. You can freeze them with or without the cream cheese frosting. Just pop them into an airtight container and freeze for up to 2 months. Alternatively, place the cookies on a lined baking tray and freeze for 2 hours. Once frozen, transfer them to a freezer-proof bag and return them to the freezer. You could also wrap them tightly in foil. To defrost, place the cookies on a wire rack or plate and let them sit out at room temperature for an hour or two until thawed. Do not refreeze.
