Preheat oven to 400°F. Lightly spray 4 4-oz custard cups or small ramekins with cooking spray.
In a medium bowl, combine cocoa powder and Sucanat; whisk in applesauce and oil.
In a small bowl, lightly whisk egg and egg white and add to cocoa mixture, whisking until smooth.
Stir in flour and vanilla until flour is combined completely; do not over mix. Divide mixture evenly among prepared custard cups, place on a baking sheet and bake for 9 minutes. Centers should be soft but sides firm. Invert cups onto serving plates; let stand a few minutes before removing cups. Garnish each cake with fruit slices, if desired, and serve warm.
