In a small microwaveable ramekin, mix the unflavored gelatin powder with cold water. Allow the gelatin to sit while you whip your cream.
1 ½ teaspoons unflavored gelatin powder, 2 tablespoons cold water
In a large mixing bowl, beat the heavy cream, powdered sugar, and vanilla extract together until it reaches soft peaks. As you move the mixer around, you should see it leave a slightly raised trail of small waves.
1 ½ cups heavy whipping cream, 1 cup powdered sugar, 1 ½ teaspoons pure vanilla extract
Heat the water and gelatin in the microwave for 5-7 seconds. You don't want it to be too hot, but just warm enough to melt and become liquid again. Stir it to ensure there are no gelatin chunks. Let the gelatin cool slightly for a few minutes before adding to the whipped cream.
Turn the mixer back on low-medium speed and slowly drizzle the melted gelatin mixture into the whipped cream mixture, a little at a time, and continue to mix it for 15 seconds.
Increase the mixer speed to medium-high and continue to whip until fluffy, stiff peaks form. You'll notice that the little waves the mixer leaves are deeper and bigger. Just be sure not to overbeat it or it may become too dense and begin to clump.
