Whisk together 2 cups heavy cream, 1/3 cup Swerve powdered sugar, and 1 tablespoon vanilla extract in a large mixing bowl until the sweetener dissolves and the mixture looks frothy.
Place the frozen ice cream bowl attachment onto your stand mixer. With the mixer running, slowly pour the cream mixture into the bowl. Mix for 10-15 minutes, or until the texture looks like soft serve.
Serve immediately, or transfer the ice cream to a freezer-safe storage container and cover. Freeze for 3-4 hours to firm up the ice cream to a scoopable consistency.
