Chocolate French Silk Pie (Copycat Bakers Square's French Silk)

My b/f loooooooves Bakers Square French Silk pie. However, the chain has closed all of its stores in Southern California. A few Valentines days ago I tried the recipe that calls for Knox Gelatin and buttermilk - that was a disaster. This recipe which I found on bigoven.com is the closest to perfection as I have been able to find. Making sure everything is well mixed is the secret to a nice high fuffy pie.
