( I call it "Robin's Pie" after my friend that introduced it to me...)
1 x 8 oz. Cool Whip
1 x large Chocolate Bar (I used the Hershey's bar that is about 6" in length and 4" wide)
1 x graham cracker pie crust
Melt chocolate in a double boiler, stirring sporadically. When the chocolate has just melted, mix the chocolate in with the Cool Whip in a large bowl. Mix thoroughly. Spoon the mixture into the pie crust, cover, and freeze.
** I top mine with additional Cool Whip before serving. Your friends will think it's a glorious masterpiece! They don't have to know it only cost $6 to make :)
