Whip the whipping cream in a mixing bowl and stop just as cream resembles the consistency of yogurt.
Add all the other ingredients in and continue whipping. It might be hard at first for the peanut butter to blend in, but just follow directions and go on beating.
When mixture is perfectly whipped and holds very stiff peaks, stop whipping. Divide cream into two (or more if you wish) small bowls and chill until hard. Just before serving, let ice cream soften in room temperature for about 20 minutes.
