Mocha Soufflés

Allow egg whites to stand at room temperature for 30 minutes.

Meanwhile, in a small saucepan, combine sugar, cocoa powder, cornstarch, and coffee crystals. Stir in evaporated milk all at once. Cook and stir over medium heat until bubbly. Remove from heat. Stir in vanilla. Pour into a small bowl. Cover surface of mixture with plastic wrap. Set aside.

Preheat oven to 375°F. In a medium bowl, combine egg whites and cream of tartar; beat with an electric mixer on medium speed until stiff peaks form (tips stand straight).

Fold about one-fourth of the beaten egg white mixture into the chocolate mixture to lighten. Fold in the remaining beaten egg white mixture. Gently pour into two ungreased 1-cup soufflé dishes. Place soufflé dishes in a shallow baking pan.

Bake for 15 to 20 minutes or until a knife inserted near the centers comes out clean. Serve immediately sprinkled with powdered sugar, if desired.
