Chill your bowl: Place a metal mixing bowl and whisk in the freezer for 2 minutes to ensure maximum fluffiness.
Add ingredients: Pour the cold heavy cream into the chilled bowl, then add the Swerve confectioners sugar and vanilla extract.
Whip to soft peaks: Using an electric mixer on medium-high speed, beat the mixture for 2 to 3 minutes until soft peaks form, meaning the cream holds gentle peaks that curl at the tips.
Reach stiff peaks: Continue beating for another 1 to 2 minutes, watching carefully, until the cream reaches stiff peaks that stand straight up when you lift the whisk.
Serve immediately: Use your whipped cream right away as a topping, or store it in an airtight container in the refrigerator for up to two days.
