Add peanut butter, chocolate chips and cream to a large microwave-safe bowl. Microwave on high in 20-30 second intervals, stirring after each interval, until smooth (this should take about 45-50 seconds).
Add in the cream cheese and beat until smooth and combined.
Add in the sugar and caramel sauce and beat until smooth.
Stir in 1/2 cup peanuts and 1/4 cup mini chocolate chips. Wrap in plastic wrap and press into a ball. Refrigerate until set (to make ahead, wrap well and freeze at this point up to 3 months).
Stir together remaining 1/2 cup peanuts and 1/2 cup mini chocolate chips in a shallow bowl. Roll chilled cheese ball in peanut mixture, pressing into an even circle as you do so. Place on a large plate with apple slices and graham crackers and serve.
