My mom makes a really good one based on this
She said she adds an extra tablespoon or so of cornstarch and an extra couple tablespoons of cocoa.

Recipe: Meringue for 9-inch Pie {Recipe adapted from Betty Crocker’s Cookbook}
4 egg whites (keep cold until ready for use for best results)
1/4 heaping teaspoon cream of tartar
7 Tablespoons sugar
1/2 teaspoon vanilla (I prefer to use clear vanilla so it doesn’t discolor the meringue)
Beat egg whites and cream of tartar in 2 1/2 quart bowl until foamy.
Beat in sugar, 1 tablespoon at a time; continue beating until stiff and glossy (Peaks should form when you pull up with a spoon}
Do not under beat. Beat in vanilla.
Spoon onto pie, sealing edges and using back of spoon to create “peaks” in the meringue.
Bake at 400° for 8-12 minutes.
