1 c. sugar
1/3 c. cocoa powder
¼ c. all purpose flour
pinch salt
2 ¼ c. skim (or 2%) milk
1 tb. Butter
1 tsp. vanilla extract
1 pastry shell (9 in) baked and cooled. (Chocolate pie crust or graham cracker are good)

In a large saucepan, combine the sugar, cocoa, flour, and salt; gradually add the milk, whisking. Cook and stir over medium heat until the mixture comes to a boil. Cook and stir for a few minutes more, until the mixture thickens. Remove from heat and stir in the vanilla and butter. Pour into the pie crust and refrigerate 2-3 hours until set. Serve with whipped cream. (This one is just heavenly, and very easy)
