Combine the flour, sugar, chocolate chips, cocoa powder, baking powder, baking soda and salt in a big bowl and stir until combined.

Combine the mashed bananas, eggs, vegetable oil and vanilla extract in another bowl and mix well.

Then fold the wet ingredients into the dry ingredients until just combined (do not over-mix or your bread will come out rubbery and tough).

Pour the batter into a 23×12.5 cm – 9×5 inch pan coated with flour or lined with baking paper.

Bake in a pre heated oven at 180°C – 355°F for about 1 hour or until a toothpick inserted in the centre comes out clean.

When ready, let it cool a bit in the pan and then place it on a wire rack to cool completely before slicing it.
