Prep Ahead Guide: This recipe is great for preparing ahead of time. Let it chill for at least 8 hours, but you can keep it in the fridge for up to 24 hours. You can also get the pudding ready beforehand if you like. If you're making the pudding ahead of time, place plastic wrap right on top of the warm pudding to prevent a "skin" from forming. You can store it in the refrigerator for up to 2 days. Making the whipped cream works best when done fresh. However, if necessary, you can make it ahead, cover it well, and let it chill in the fridge for up to 24 hours before using it.
