I've used some peanut pies that were almost too rich, if I remember several had cream cheese?
wouldn't mind taking a look at yours though? If it's not too much trouble.
The way I do it now, is just use the recipe for filling that I use for banana or coconut pie (milk, flour or cornstarch, sugar, eggs etc.) when it is still hot, I whisk about a cup of peanut butter in, put in crust, add meringue, brown.
