Pre heat the oven to 180C and grease a 9 X 5 inch loaf pan and keep aside. If you want you can also line it with parchment paper, but if you grease the pan well, the loaf doesn't stick and comes out easily

Roughly mash bananas in a large bowl, I like a little bit of piece coming here and there, so I use the whisk or potato masher to mash, I do not puree them, however, if you prefer you can puree them as well. Add olive oil on top and whisk till combined.

To the above add 2 eggs and whisk till everything is incorporated. Keep aside

Sieve together whole wheat flour, baking powder, baking soda, cocoa powder and cinnamon. Add raw sugar to this and mix.

Add the dry ingredients to the wet (eggs, banana and oil) and using a spatula to mix till fully incorporated.

Add the chopped dark chocolate and mix well. Pour in the prepared loaf tin and bake at 180C for 50-55 mins or till the skewer comes out clean in the middle.

Let cool completely before taking it out of the tin and slicing.

Serve with tea/coffee as a tea time treat or with ice cream as after meal dessert.
