no bake peanut butter cheese pie.

First of all, this is one of the most delicious cheese cakes/pies. One of my biggest weakness is cheese cake. I made it last year and it was really fabulous. I made the crust with gluten free bisquits and ground almonds (for my gluten free's). My question is why davka pareve whipping cream. If I make it with milchig, will it affect the consistency? Thanks!
