Add the whipping cream to the bowl of a stand mixer (if you don't have a stand mixer use a large mixing bowl and a handheld mixer) Whip the cream for one minute on a medium speed. Slowly add the sugar to the cream. Turn off the mixer and check to see that the gelatin has cooled, but not set. Add the gelatin and continue to whip until stiff peaks form. Separately reserve about 1 - 1 1/2 cups of whipped topping for garnish.
