In a different bowl cream both sugars and butter together. Beat on medium for 1-2 minutes or till the mix becomes light and fluffy.
Into the mix add eggs and vanilla. Beat on med speed till eggs are incorporated.
In a different bowl mash ripe bananas. No need to get a perfect puree.
Mix banana puree into the sugar-butter mix.
Add ¾ part of the dry ingredients and mix with a spatula just until the four disappear
Add milk and mix well. Add the rest of the dry ingredients and chopped chocolate. Mix well.
Pour the batter into the loaf pan.
