Place gelatin in a small bowl.
Add the cold water and stir slightly. Let stand for 5 minutes.
Add the heavy cream to a stand mixer and add the powdered sugar.
Whip on medium speed until soft peaks form.
After the 5 minutes, place the gelatin in the microwave for 10 seconds.
It should be liquified and clear. If not, microwave for another 10 seconds.
Stir the gelatin until it cools a bit.
While continuously beating the heavy cream on medium speed, add a teaspoon of liquid gelatin at a time.
Continue beating until all gelatin is added.
Beat for another 10- 15 seconds or longer until the whipped cream is thick and smooth.
*Full Disclosure - I used 3 teaspoons of gelatin, 4 1/2 tablespoons of water, 1/2 cup of powdered sugar and three cups of heavy cream to cover the top of this 13 x 9 pan. I made the full recipe and halved it again.
