I topped with whipped cream. I am sure this will be a very unpopular opinion, but I really don't like whipped cream. I know. So many people think that's weird. I get it, but I never liked it and I never will. So full disclosure here, I added the whipped cream because it made the mousse look prettier. But when I eat these babies at home you better believe there will be none of that nonsense on top. Maybe some granola, chocolate chips or sliced nuts, but definitely not whipped cream.
