2 cups heavy whipping cream (very cold)
4 tbsps powdered sugar
2 tbsps vanilla extract (or other flavored extract)
2 tsps powdered gelatin (unflavored, Knox)
2 tbsps water
Pour cold heavy whipping cream, powdered sugar, and vanilla extract in a 1 pint whipped cream dispenser.
Meanwhile, combine gelatin powder and 2 tbsps water in a small glass bowl. Once water has been fully soaked up by the gelatin, microwave the mixture for 15-20 seconds. It should become a thick, hot liquid. Stir well and let sit at room temp.
Pour liquid gelatin into the dispenser and charge with 1 N20 charger and dispense.
