Chill your mixing bowl and beaters or whisk attachment in the fridge for about 15 minutes beforehand.
Pour cold heavy cream into the chilled mixing bowl and begin to beat with an electric mixer on medium-high speed.
Once the cream begins to thicken, gradually add in the sugar, while continuing to beat the cream.
If desired, add in vanilla extract and continue beating until soft peaks form. (Be careful not to overbeat the cream! Stop beating once you achieve a smooth and fluffy consistency).
Notes
Use immediately or cover tightly and chill in the fridge for up to 1-2 days. You can freeze homemade whipped cream, however it does change the texture a bit!
