Whisk the cold heavy cream, vanilla extract, and powdered sugar until well combined and the sugar has dissolved. I just use a large measuring cup!
Pour the mixture into the whipped cream dispenser, no higher than the max fill line, and tightly screw on the lid.
Place one N2O cartridge in the cartridge holder and screw it on to charge the dispenser. It will make a hissing sound.
Give the dispenser 3 to 4 good shakes. Pointing the nozzle fully downward, slowly and carefully press the trigger. Enjoy!

Recipe Notes
Flavors: Want maple, mocha, amaretto or pumpkin spice? All 11 flavors are in the post above. Whisk until everything is fully dissolved and strain anything with cocoa, coffee or spice so it doesn't clog your nozzle.Quart dispenser: Double everything and use 2 chargers.Make ahead: You can keep the charged dispenser in the fridge. Use it before the expiration date on your cream, and shake well before each use. You may need to recharge it with another N2O cartridge.Be sure to release all of the gas prior to opening the dispenser! Otherwise the contents will spray everywhere!
