Crush the cornflakes (Both 1/2 and 1/4 cup together)coarsely or grind it in a mixer like I did. In a mixing bowl – add butter, vanilla essence and sugar.
Beat it well with a whisk until fluffy and creamy.
Sieve flour and baking powder twice at least.
Now add the flour and 1/2 cup cornflakes and mix gently to form a soft dough. If the dough is too crumble add 1 teaspoon of water and knead it.
After forming the dough refrigerate for 15-30 mins.
Then take out the dough and roll it to a cylinder and cut into small equal pieces.
Preheat oven to 170 deg C for 10mins.
Meanwhile roll them into balls and slightly flatten them using your palms , now dip it in the cornflakes mixture (1/4 cup) so that it is evenly coated on all sides.
Arrange the cookies in a parchment sheet / butter paper leaving 1 inch gap (the cookies don't spread much).
Bake the cookies for 12-15mins keeping the tray in the middle rack or until the edges start browning.
