Place the avocado skins inside the freezer for 10 minutes to make them more stiff. Note: you'll need a second set of avocado skins, so save them from a previous recipe or make some guacamole or avocado toast while you're making this recipe and save them.
Want more of the chocolate banana pits? Make a full circle rather than a half. Once the avocado ice cream is frozen, scoop out enough room for the pit with a spoon and add the round pit.
