Instructions:

Chill a mixing bowl and the whisk attachment in the freezer for 10-15 minutes.
Pour the heavy cream into the chilled bowl and whisk on medium speed for 1-2 minutes until it starts to thicken.
Add the powdered sugar and vanilla extract and continue to whisk until the cream forms stiff peaks.
Be careful not to over-whisk, or the cream will become grainy.
Use immediately or store in the refrigerator until ready to use.
