The recipe I had for this pie actually called this pie French Silk but being the pie expert that I am, it isn't light and silky; it is more like fudge so I had to change the name to make it fit. (Maybe we just made it wrong and it really is silky:)) Whatever it is, it's good though.
1 cup sugar
3/4 c. butter
3 squares unsweetened chocolate, melted, and cooled
1 tsp vanilla
Baked pie crust
Beat sugar and butter on medium speed about 4 minutes til fluffy. Add chocolate and vanilla. Add eggs, one at a time, beating on high after each addition and scraping sides of bowl constantly. Put into pie shell. Cover and chill 5-24 hours. Top with whipped cream and chocolate curls.
