1-Combine ingredients: In a medium saucepan, combine 1 cup sugar, 4 heaping tablespoons cocoa powder, 3 tablespoons cornstarch, and a pinch of salt. Add 2 cups whole milk and bring the mixture to a boil, cooking for 1 minute. In a separate bowl, beat 4 egg yolks, then gradually stir a small amount of the hot milk mixture into the egg yolks to temper them before pouring it back into the saucepan.

2-Cooking the Filling: Cook the mixture over medium heat, stirring constantly, for about 3 minutes until it thickens. Once done, remove from heat and stir in 1 teaspoon vanilla, 2 tablespoons butter, and 1/4 cup semi-sweet chocolate chips until everything melts smoothly. Pour this rich filling into the 9-inch pre-baked pie crust and set it aside.

3-Prepare the meringue: For the meringue, beat 4 egg whites, a pinch of salt, and 1/4 teaspoon cream of tartar with an electric mixer until stiff peaks form. Slowly add 1/4 cup sugar and a few drops of vanilla while beating to keep it light. For more tips on making meringue, visit this helpful resource: making meringue guide.

4-Baking and Finishing: Spread the meringue over the hot filling, making sure it’s sealed completely around the edges. Bake at 325 degrees Fahrenheit for about 20 minutes or until the meringue turns golden brown. Let the pie cool for several hours before serving to set everything perfectly. This approach ensures your Chocolate Meringue Pie with crispy topping comes out just as you’d hope.
