In a bowl, stir together the mashed bananas, applesauce, splenda, egg, and vanilla until combined. Add the flour, baking soda, cinnamon, and salt, mix until just combined. Fold in the chocolate chunks.
Pour the batter into microwave-safe mug(s). Microwave on full power for 1 minute and 35 seconds to 2 minutes (I always do 1 minute 35 seconds, but it's better to under "bake").

To Oven Bake: Preheat the oven to 350 degrees F. Lightly grease a 2 cup oven safe ramekin/mug or 2 muffin tins. Add the batter and bake 22-25 minutes.  To Oven Bake: Preheat the oven to 350 degrees F. Lightly grease a 2 cup oven safe ramekin/mug or 2 muffin tins. Add the batter and bake 22 to 25 minutes.
Microwave: every microwave is very different, so results may vary slightly. I have a 1100 watt microwave and found 2 minutes to be the perfect cooking time with 2 10 oz mugs. You may need to cook 1 minute 45 seconds or 2 minutes 15 seconds. Start with 2 minutes.  Microwave: every microwave is very different, so results may vary slightly.
