I have a mad love affair with peanut butter pie, but some varieties are just too dense... I prefer mine a bit on the creamy side. A somewhat unassuming local bar/restaurant (which nevertheless had awesome food!) used to get the most fantastic pies made for them by a woman who lived nearby -- light, fluffy, pure heaven! It was that heavenly pie that I was attempting to duplicate when I came up with this recipe. My fellow peanut butter lovers so far have given it rave reviews.
