This is a healthier version than the conventional. Be sure to use the "lighter" ingredients as listed to ensure that it is healthier. HINT: The frosting firms up as it rests. If it becomes too firm to spread, gently warm it in the microwave on medium power for 30 seconds, or until softened. This cake actually tastes better when made a few hours before serving. As soon as the cake is frosted, cover it with plastic wrap and refrigerate. Let stand at room temperature for about 30 minutes before serving and refrigerate for up to 4 days.
