Firstly, sieve wheat flour, cocoa powder, baking powder, baking soda and cinnamon powder together, twice. Keep it aside.

In a big mixing bowl take peeled bananas and mash it with the help of a fork or you can also blend it in a blender.

Add in the oil, sugar, vanilla essence and milk. Mix well.

Now add the flour mixture in 2-3 batches into the wet mixture and mix it by cut and fold method.

If the batter getting too thick then consistency can be adjusted by adding more milk.

Do not over mix. Now pour the batter into a greased cake tin and bake it in a pre heated oven at 180° for 30-35 minutes.

Allow it to cool down completely. Then cut the slices, drizzle some chocolate syrup and serve.
