Pat the bowl in the bottom to spread the batter evenly. Microwave it in high power ( i used 800for 3-5 minutes.Check at 3 minutes.If not done,keep it for more time.Mine took 4 minutes.Check it with the back of spoon or tooth pick.If it comes out clean,cake is done.Else keep it for one more minute.Cake will rise but wont double. Remove & keep it outside. Let it cool down (If you want to decorate it as you like). Then invert the cake,cut into pieces and enjoy ! If u try to remove the cake before it cools down,cake will crack.If u use butter paper,u can remove it easily.
