This grown-up birthday cake blends delicately crisp meringues, orange-scented cream, a hint of chocolate, and fresh fruit. Superfine sugar dissolves quickly into the beaten egg whites; if you can't find superfine sugar in your grocery store, make your own by processing granulated sugar in a food processor for about a minute. If you can't find clear vanilla extract, use regular vanilla extract; your meringue will be a little darker but just as delicious. Prepare the meringues up to three days ahead, and store at room temperature in an airtight container. Top with filling and fruit shortly before serving.Meringues are made with egg whites, which are low in cholesterol and fat. Served with a variety of antioxidant-rich berries, enjoy this healthier version of regular birthday cake.
