Optional but helpful is to chill your mixing bowl before whipping.
Bloom the gelatin by sprinkling the gelatin over water and letting sit for about 5 minutes.
Once it’s bloomed, heat in the microwave for 5-10 second intervals until it has totally dissolved (about 20-30 seconds total). Do not over cook the gelatin, or it can lose it’s setting ability.
Once it’s dissolved, remove from the microwave and stir in the extra cream. The cream should cool down the mixture. If the mixture starts to set before using, reheat until melted again. Just make sure it’s cooled down a bit before adding to the whipping cream.
Add sugar, whipping cream, and vanilla in a preferably cold bowl.
Mix on low until it starts to thicken and soft peaks form. Slowly add the gelatin mixture and continue beating until firmer peaks start to form. Once you get firm peaks stop mixing. Do not overbeat the mixture or it can start to get lumpy or break.
Pipe or use on your dessert and enjoy!
