OK ... back in the day, Mom's made this stuff with cream cheese, peanut butter AND Cheese Whiz! So they got creative and used the cheesecake cream cheese. Why stop there? Why not pineapple, strawberry or raspberry flavors? Or maybe one of the savory flavors.
Don't know why you need the raisins tho ... they're old fruit ... I don't eat old ANYTHING! Throw em out! Just tell the kids the ants took a dive and went swimming. ;)
