>
2/3 + 1/4 cup sugar, divided
>
1/8 tsp salt
>
2 tbsp unsweetened baking cocoa

Steps
1
Preheat oven to broil. In a large saucepan, combine flour, ⅔ cup sugar, salt, cocoa, and milk. Heat on low 20 minutes, whisking constantly, until thick.
2
In a medium bowl, whisk egg yolks. Whisking constantly, pour a small amount of hot cocoa mixture into eggs. Pour egg mixture back into saucepan and cook until thickened slightly more, about 5 minutes. Remove from heat. Add butter and vanilla to saucepan and stir until combined. Pour mixture into pie crust.
3
To a clean mixing bowl, pour in egg whites. In a stand mixer with whisk attachment or with a hand mixer, whip egg whites until glossy and smooth. Slowly add remaining ¼ cup sugar to egg whites about 1 tablespoon at a time, beating after each addition until sugar is fully incorporated. Continue beating until stiff peaks form.
4
Top chocolate cream pie with meringue. Place pie on a sheet pan and place on center rack of oven. Broil 3 to 5 minutes, watching carefully, until golden brown. Remove from oven and let cool. Refrigerate at least 3 hours or up to overnight before serving.
