Now this is a wonderful peanut butter pie! It is an adaption that I have created from two pie recipes. The pretzel crumb pie shell adds another dimension to this pie. I like to prepare the pretzel crumb pie shell, bake and cool it prior to making the filling. That could be done in the morning and the filling mid-afternoon. I'm posting it here because I want to be sure I don't lose this precious recipe. The chill time isn't included in prep time.
