No bake banana pudding can be frozen. Here's how: Transfer the pudding into an airtight container or freezer bag, leaving some space at the top for expansion. Label the container or bag with the date and contents. Place the container or bag in the freezer and freeze for up to 2-3 months. When ready to eat, thaw the pudding in the refrigerator overnight, or at room temperature for a few hours. Once thawed, give the pudding a good stir to help redistribute any liquid that may have separated. Keep in mind that freezing no bake banana pudding may change its texture and flavor, so it may not be as enjoyable as when it's freshly made.
