Old Fashioned Chocolate Pie Recipe

Directions

Preheat the oven to 350°F (175°C).
Melt butter in a saucepan over medium heat.
In a bowl, mix sugar, flour, and cocoa powder. Gradually whisk the mixture into the melted butter until smooth.
Slowly add the milk, whisking constantly. Cook over medium heat for 5-7 minutes until thickened.
In a small bowl, whisk egg yolks. Add a spoonful of the hot chocolate mixture to the yolks to temper them, then whisk back into the saucepan.
Cook for 2-3 additional minutes, stirring constantly. Remove from heat and stir in vanilla extract.
Pour the chocolate mixture into the pre-baked pie crust.
