The egg in the cake does add to the fluffiness and the eggless cakes some what lack there. So why not give your cakes the same fluffiness without adding eggs but using egg substitutes?
One substitute which I commonly found while googling was the FLAXSEED.
Flaxseed is also known as Linseed. It is called 'Avise Ginjalu' in Telugu, 'Ali Vidai' in Tamil, 'Alsi' in Hindi. I hunted for it big time at Big Bazaar, Spencer's Hyper but failed. I finally bought it when I made a trip to Chennai. I found it easily at Nilgiris. You can also find flaxseed in 'Nuts and Spices' outlet and there is one in Hyderabad too.
To
substitute 1 egg, add 3 tbsp warm water to 1 tbsp flaxseed powder (in stores you get flaxseed in the powder form) and let it stand for 10 minutes. After 10 minutes you would find that it gets quite the same texture as that of an egg. It serves the binding purpose that the eggs are used for in the cakes. These days most people are using flaxseed instead of eggs for its health benefits and for the lower calories as compared to eggs.
Flaxseed can also be used in soups. Checkout my
Tomato Oats soup recipe for the same.
