Line a 9" X 5" loaf pan with wax or parchment paper and set aside.

In a small bowl, stir together the peanut butter, sugar, cream cheese, and warm melted butter until well combined. Drop it by the spoonful (in chunks) onto the bottom of the prepared pan.

In a small pot, melt together the chocolate and cream on low heat. Stir until smooth, then pour on top of the peanut butter chunks and spread into one even layer.

Cover and freeze for 1 to 2 hours or until the chocolate is set. Store the leftovers in the fridge.
