Preheat the oven to 350 degrees. Spray 1 bread pan with non-stick cooking spray.
In a small bowl, mix the baking soda, baking powder and mashed bananas. Set aside.
In a large mixing bowl, mix the sugar and oil. Add eggs one at a time and mix well. Set aside.
In a medium bowl, sift flour and salt together.
Add the flour mixture and ½ cup of water to the sugar, oil, and eggs alternately, a little at a time. Start with a little flour, then add a little water. Repeat until all the flour and water have been added.
Add the banana mixture and stir gently until combined.
For the chocolate: Combine the chocolate chips and ¼ cup oil in a microwave-safe bowl. Microwave in 30-second intervals, stirring after each interval, until completely melted and smooth.
Pour the melted chocolate into the bowl with the batter, gently folding and swirling until distributed.
Pour the batter into the bread pan and bake for 50-60 minutes or until a toothpick inserted into the center comes out clean.
