In a bowl, add the vegetable oil, the powdered sugar, beat the eggs and add the vanilla essence.

Beat them very well with a egg beater or hand blender.

In another bowl fit a strainer and add the maida, baking soda, baking powder and Cocoa powder on it. Strain them very well to avoid lumps.

Add this mixed dry powder, little by little in the bowl, consisting of all the liquid ingredients. Continuously mix them while adding the powdered mixture to avoid any lumps.

Mix them very well with an egg beater to avoid any lumps.

Grease a microwave proof bowl and preheat it for 1 minute.

Add the cake mixture in the microwave proof bowl.

Bake it in the convection mode at 180 degree for 35minutes. Basically the timing depends on the power of your microwave oven. Therefore check the cake with a fork after 35minutes. If not cooked well then again bake it for 5-10minutes. I always cook it for 35minutes.

After 35 minutes keep it inside the microwave oven for 10minutes and after that serve hot or cold.
