A homemade silky smooth chocolate pudding becomes the filling for the most delicious chocolate pudding pie. Forget pudding from a box! Once you’ve made your own, no other will compare!
Prepare the frozen pie crust according to package instructions. Allow to cool completely.
In a medium sized saucepan, mix sugar, cocoa, flour, salt, and egg until well blended. Stir in milk slowly until ingredients are blended.
Over medium heat, stirring constantly, bring to boil. Continue to cook, stirring constantly, three to five minutes, or until pudding thickens slightly.
Remove from heat; stir in butter and vanilla.
Pour into baked pie shell. If desired, cover with plastic wrap directly on surface of pudding to prevent a skin from forming. Refrigerate 4 hours, or up to 24 hours.
Top with whipped cream, and chocolate shavings, if desired, and serve.
