Whip the chilled heavy whipping cream on medium-high speed for 2–3 minutes until stiff peaks form, then transfer to a separate bowl.

Blend the softened cream cheese and powdered sweetener in the same bowl on medium speed for about 2 minutes until smooth and fluffy.

Fold a third of the whipped cream into the cream cheese mixture, then gently fold in the remaining whipped cream until fully combined.

Spoon into serving bowls or jars. For a firmer texture, refrigerate for at least 30 minutes before serving.
