French Silk Chocolate Pie
["9-inch pie shell, baked and cooled", "1/2 c. butter, room temperature", "3/4 c. granulated sugar", "2 eggs", "1 sq. unsweetened chocolate, melted and cooled", "1 tsp. vanilla", "1/2 pt. heavy cream, whipped (optional)", "1/2 c. finely chopped pecans (optional)"]
["Cream butter until smooth. Gradually add sugar. Add eggs, one at a time, beating 3 minutes after each at highest speed (it helps to have a good book or great music on loud to get through this part). Add cooled chocolate and vanilla. Beat well. Pour into pie shell. Chill 2 hours. Top with whipped cream and nuts. Very rich. Serve in small pieces."]
