4 eggs
1 1/3 c. sugar
7 heaping tbsp. flour
4 heaping tbsp. cocoa
2 2/3 c. milk
1 tbsp. butter
1 tsp. vanilla
2 baked regular pie crusts

Mix the first 5 ingredients in a blender. Pour in double boiler and cook until thick. Stir from sides of pot several times while cooking. Pour back in blender and add the butter and vanilla. Beat until smooth. (Start with low speed and go to high speed on blender.) Filling will become very smooth and silky. Pour into the pie crusts. Filling thickens immediately. Let set until cool. Serve with Cool Whip.
