In a bowl, add wheat flour, salt, sugar and mix them well.
In a mixing bowl add egg and vanilla essence. Use a hand blender to mix them well. The mixture can be fluffed to get a smooth texture.
Meanwhile, mash the banana either using a blender or a hand blender.
Now add the flour mixture and banana into the wet mixture. Beat the mixture for 2 minutes until everything mixes well together.

In a steamer, cook the batter for 3o minutes.
Use a toothpick to check in the middle part of the batter is cooked.
Remove the pan from the steamer. Remove the pudding from the pan. Allow it cool down.
