There are many different methods for making whipped cream frosting, but personally I found that this method yielded the most stable results with the most authentic whipped cream taste. I tried many methods including using more powdered sugar (made the frosting too sweet and did not last as long as this version with gelatin), using a food processor (didn't hold its shape long enough and still melted), adding cream cheese (tasty, but changed the taste far too much) and using powdered milk (this worked fairly well, but did not hold its shape as long and modified the taste a bit). Ultimately I recommend sticking with the method written in my recipe below.
