Place ½ cup of heavy whipping cream into a mixing bowl. Beat on high until it is whipped into stiff peaks. Be careful not to overmix it, or it will begin to make butter. Place the whipped cream into a separate bowl, and reserve it for later.

In another mixing bowl, add together the cream cheese, stevia drops, peanut butter and vanilla extract. Mix the ingredients together on medium speed for 1-2 minutes until they are creamy.

Return the whipped cream to the mixing bowl with the cream cheese mixture, and mix all of the ingredients together for another minute.

Spoon into serving containers, and top with grated dark chocolate for garnish if desired.
