Add the chopped berries, confectioners sweetener, and vanilla extract in a saucepan. Heat the mixture over medium-high heat until it begins to simmer.

Stir the mixture well and reduce the heat to medium for approximately 10 minutes, stirring occasionally.

When the mixture has reduced and begun to thicken remove from heat. Allow the sauce to cool completely before adding to the cheesecake mixture.

In a medium to large size mixing bowl add the softened cream cheese and powdered sweetener. Use an electric mixer to beat the mixture until it is creamy.

Next, add the sour cream and vanilla extract and beat the mixture again until combined. The final step is to add the heavy cream and beat the mixture until it has doubled in volume and is thick, fluffy, and creamy like the second photo above. At this point, you can cover and chill the mixture or assemble the jars.
