Peanut Butter Cream Pie

Okay, this one has a video I made for Philadelphia Cream Cheese, so get ready to drool as you watch how easily this no-bake pie comes together.  Peanut Butter Cream Pie is rich and delicious, too-- perfect for company or week nights.  I first heard of this recipe from my sister-in-law, Sherri Hilton, but there are dozens of variations of it online as well.  The original called for superfine sugar, but I made some modifications (powdered sugar instead of superfine sugar, for example), and also created some variations you can try, listed below the recipe.

1.  (What?  Only one step? Yep.) In a large bowl, beat cream cheese, peanut butter, melted butter, and sugar until smooth.  Fold in whipped topping, then spoon into crust and chill.  When ready to serve, cover with additional whipped topping and garnishes as desired.
