Take a vessel & put all dry ingredients .....multi grain atta,baking soda,baking powder & salt .Mix nicely.Keep aside.
In another vessel,mix all liquid ingredients ...oil,grated beetroot carrot mix,apple puree,dahi,oil .Add sugar.Mix nicely.
Make a well in the dry ingredient mix & pour the liquid mix into it.Whisk with a spoon so that no lumps remain.The cake batter thus ready must have drop down consistency.Add water if the batter is very thick. Keep aside.
Line the bottom of a a microwaveable vessel with butter paper .Pour the cake batter into it.Microwave for 10 minutes.Put off the microwave.Let it cool for 10 minutes..Insert a knife in the middle of the cake.If knife comes out clean ,it is done.If not,microwave for 1-2 minutes more.Cool & check again.
