Chocolate-Filled Meringue Sandwiches Recipe

Preheat oven to 175°F. Line baking sheets with parchment paper or silicone mats.

Place egg whites and sugar in a metal mixing bowl. Place bowl over a pan of simmering water, making sure the water doesn’t touch the bottom of the bowl. Beat using a wire whisk for about 3 minutes or until mixture is warm to touch.

Add cornstarch, vanilla, cream of tartar, and salt to egg mixture. Transfer mixture to the bowl of an electric mixer fitted with the whisk attachment. Whip mixture until stiff peaks form and eggs are cool.
