Chocolate Cinnamon Meringue Pie

I started with this recipe and added my own little flair to it:

Crust:

One 9-inch pie crust, store-bought or homemade, unbaked (fitted in a pie plate)

Filling:

2/3 cup sugar

3 tablespoons unsweetened cocoa powder

2 tablespoons all-purpose flour

1 tablespoon cornstarch

1 can (12 ounces) evaporated whole milk

3 eggs yolks

3 tablespoons unsalted butter, cut into small pieces

1 teaspoon pure vanilla extract

Meringue

1/3 cup sugar

1 teaspoon cornstarch

3 egg whites

1 tsp cinnamon

Directions:

Preheat oven to 375 degrees. Place pie crust in plate on a rimmed baking sheet; bake until crust is golden, about 20 minutes (or follow directions on store-bought package). Cool completely; set aside.

Put a fine-mesh sieve over a medium bowl; set aside. In a medium saucepan, off heat, whisk together 2/3 cup sugar, cocoa powder, flour, and 1 tablespoon cornstarch. Gradually whisk in evaporated milk. Whisk in egg yolks.

Place pan over medium heat; whisking constantly, cook until the first large bubble forms, about 5 minutes. Reduce heat to low; whisking constantly, cook 1 minute.

Immediately pour mixture through prepared sieve into bowl. Stir in butter and vanilla. Pour warm filling into baked crust; cover surface directly with plastic wrap. Chill at least 2 hours and up to 1 day.

Preheat oven to 450 degrees. Using an electric mixer, beat egg whites, remaining 1/3 cup sugar, 1 teaspoon cinnamon, and 1 teaspoon cornstarch until stiff peaks form. Spread meringue on top of filling, right up to edge of crust; bake until meringue is lightly browned, 5 to 7 minutes. Serve immediately.

If you are preparing for the next day, let the pie cool to room temperature and then refrigerate.
