Chocolate cream pie

Suddenly I felt like chocolate pie, don't know where it came from. Kinda blame it on watching The Help again...lol 

So here is my variation of the Chocolate pie! 

9 inch pie crust, baked

3 cups skim milk

1 1/2 cups white sugar

1/2 cup unsweetened cocoa powder 

Pinch of salt

3 egg yolks, beaten

1 tbs butter

1 tbs vanilla extract 

3 tbs corn starch

In a big bowl beat egg yolks with salt and sugar, add corn starch, vanilla, milk and cocoa powder. 

Pour the mixture in a pot and put it on the stove on medium high, stirring constantly until it boils. 

Pour it right away in a clean bown and add the butter, mix it till it melts. 

Leave it aside for 15-20 mins to cool. 

Pour everything in the cooked crust and leave it in the fridge for a couple of hours.
