If you like, chill a large mixing bowl (or the bowl of your stand mixer) and the whisk attachment to your mixer for at least 10 minutes before beginning.
Pour very cold cream into mixer.
Add sugar and vanilla.
Beat on medium to medium-high speed until cream reaches the stage your recipe calls for: soft, medium, or firm peaks. Watch the video in this post and consult the photos above for visual cues.

Notes
Whipped cream is best used fresh, but keeps, tightly covered, in the fridge for about three days
