1/4 cup unsweetened cocoa
3 tablespoons cornstarch
1/4 teaspoon salt
2 1/4 cups cold milk
1 teaspoon vanilla extract
1/2 pint (1 cup) heavy whipping cream
2 tablespoons confectioners' sugar
DirectionsBake the pie shell according to package directions in a 9-inch pie plate; let cool.
Meanwhile, in a medium saucepan, combine the granulated sugar, cocoa, cornstarch, and salt. Gradually stir in milk. Bring to a boil over medium heat, stirring constantly. Remove from heat and stir in vanilla. Pour into pie crust and chill 1 hour.
