Add the water to a microwave safe bowl and sprinkle the unflavored gelatin on top. Allow to sit for a few minutes.

Transfer the gelatin mixture to the microwave and microwave until the gelatin is fully dissolved, this will just take a few seconds. Stir the mixture, then set aside to cool.

In the bowl of a stand mixer fitted with the whisk attachment, or in a large mixing bowl using an electric mixer, combine the heavy whipping cream, powdered sugar, and vanilla extract. Whip the mixture until it starts to thicken and soft peaks form, then turn the mixer to low speed. Slowly pour in the gelatin mixture until well combined. Increase the mixer to medium speed and continue mixing until stiff peaks form.

Pipe the whipped cream on your favorite dessert (or use it to frost it) and refrigerate your dessert until ready to serve.
