Since avocados tend to oxidize really fast, I don't recommend you to make this pudding ahead of time. You can whip it up in a matter of minutes, so it's best to make it and enjoy it right away. You can store it in an airtight container, covered, for up to 1-2 days, but keep in mind that it won't retain the same flavor and the taste of the avocado will become noticeable. This chocolate-infused avocado dip is not freezer-friendly, too.
