Creating your Homemade Chocolate Pie can be easy if you follow these simple instructions:

1. Preheat the Oven: Begin by preheating your oven to 350°F (175°C).

2. Make the Crust: In a mixing bowl, combine graham cracker crumbs, melted butter, and sugar. Mix until crumbly. Press this mixture evenly into the bottom and up the sides of a pie dish.

3. Bake the Crust: Place the crust in the preheated oven and bake for about 8-10 minutes. Remove from oven and let it cool while preparing the filling.

4. Prepare the Filling: In a saucepan, whisk together sugar, cocoa powder, cornstarch, and salt.

5. Add Milk: Gradually whisk in the milk until smooth. Place the saucepan over medium heat.

6. Cook: Stir the mixture continuously until it begins to thicken and bubbles form, about 5-10 minutes.

7. Add Eggs: Remove from heat. In a separate bowl, beat the egg yolks. Slowly pour a little of the hot mixture into the yolks while whisking constantly to temper them. This prevents scrambling.

8. Combine: Pour the egg mixture back into the saucepan and return to heat. Cook for another 2-3 minutes until thickened further.

9. Finish the Filling: Stir in the vanilla extract and butter until smooth.

10. Fill the Crust: Pour the chocolate filling into the cooled pie crust, spreading it evenly.

11. Cool the Pie: Let the pie cool at room temperature for about 30 minutes, then refrigerate to set for at least 1 hour before serving.

12. Prepare to Serve: Optionally, top the pie with whipped cream, chocolate shavings, or fresh berries just before serving.

These steps will guide you effortlessly in creating this incredible pie that will leave everyone wanting more!
