I have tried peanut butter and cream cheese and peanut butter and cream. I didnt like the cream cheese... it just tasted odd to me. When I make ziplock bag Ice cream I add some melted PB and that goes great.

BTW I use the smuckers brand of natural PB because it shows less aflatoxins than the no name brand of all natural PB. There are many all natural brands though, or you can just make your own with some peanuts.
