Step 1: Bake the Pie Crust

Bake the pie crust as per package instructions or your go-to recipe. Once baked, allow it to cool completely before proceeding to the next step.

Step 2: Whip Up the Chocolate Filling

In a medium saucepan, combine cocoa powder, sugar, flour, and milk. Use a whisk to blend the ingredients thoroughly until combined. Add in the egg yolks and butter, then place the saucepan over medium heat. Cook the mixture, stirring continuously, until it becomes smooth and thick. Once thickened, remove from heat and stir in vanilla extract. Pour the chocolate filling into the cooled pie crust.

Step 3: Master the Meringue

In a large mixing bowl, beat the egg whites and cream of tartar using an electric mixer on medium speed until soft peaks begin to form. Gradually add sugar to the egg whites, continuing to beat on high speed until stiff peaks form and the mixture is glossy.

Step 4: Bake to Perfection

Carefully spread the meringue over the chocolate filling, ensuring the meringue touches the edges of the crust to prevent shrinking. Preheat the oven to 350°F (175°C) and bake the pie for 10-15 minutes or until the meringue is beautifully golden and toasted.

Step 5: Cool and Serve

Once baked, remove the pie from the oven and allow it to cool completely at room temperature before slicing and serving. Enjoy your old-fashioned chocolate pie!
