Ingredients:
Chocolate Filling
- 1 pre-baked 9-inch pie crust
- 1/4 cup unsalted butter
- 1 cup granulated sugar
- 1/4 cup all-purpose flour
- 1/2 cup unsweetened cocoa powder
- 2 cups whole milk
- 4 large egg yolks (reserve whites for meringue)
- 1 teaspoon vanilla extract
- 1/4 teaspoon salt
Meringue Topping
- 4 large egg whites, room temperature
- 1/4 teaspoon cream of tartar
- 1/2 cup granulated sugar
- 1/2 teaspoon vanilla extract
Instructions:
Make the Chocolate Filling
- In a medium saucepan, whisk together the sugar, flour, cocoa powder, and salt.
- Gradually whisk in the milk until smooth.
- Place the saucepan over medium heat, stirring constantly, until the mixture thickens and begins to bubble.
- Cook for 1 minute, then remove from heat.
- Whisk a small amount of the hot mixture into the egg yolks to temper them. Gradually whisk the yolks back into the saucepan.
- Return to medium heat and cook for 2 more minutes, stirring constantly, until thick and glossy.
- Remove from heat and stir in butter and vanilla until smooth.
- Pour the hot filling into the pre-baked pie crust.
Make the Meringue
- Preheat oven to 350°F (175°C).
- Beat egg whites and cream of tartar on medium speed until soft peaks form.
- Gradually add sugar, one tablespoon at a time, beating until stiff, glossy peaks form.
- Beat in vanilla extract.
Assemble and Bake
- Spread the meringue over the hot chocolate filling, making sure it touches the crust edges to seal.
- Create decorative peaks with the back of a spoon.
- Bake for 12–15 minutes, or until the meringue is lightly golden.
- Cool completely at room temperature, then refrigerate for at least 2 hours before slicing.
Tips for Best Results
- Always spread meringue over hot filling to prevent weeping.
- Use room-temperature egg whites for maximum volume.
- Slice with a clean, sharp knife for neat servings.
