I made some changes like substituted maida with wheat flour etc.
Ingredients : 1/2 cup whole wheat flour ( used Pillsbury brand ),1/4 cup powdered oats ( 1/4 cup oats which was powdered in mixer ) ,1/4 cup corn meal & powdered dry fruits ( 6 pistas,6 almonds & 6 hazelnuts- actually one can substitute other dry fruits ),heaped 1/2 cup jaggery sugar( Ishan brand available in Rajkamal tea Chembur ,Mumbai ) ,1/4 tsp cinnamon powder,1/2 tsp baking soda,1 tsp baking powder,1 /4 tsp salt,1/4 cup dahi or yoghurt,1/4 cup oil,1 apple grated.
Method : Take a bowl & mix atta,corn meal-dry fruit mix & powdered oats nicely.This flour mix can be sieved to get a good mix.I used jaggery sugar as I got it locally here.It is healthier than sugar.Ordinary sugar can be used.Mix sugar with the flour mix.Add baking soda,baking powder,cinnamon powder & salt to the flour -sugar mix.Mix all dry powders nicely.Keep aside.
Mix oil & yoghurt nicely in another bowl.Grate the apple & keep in a plate.
Make a well into the dry mixture & pour the yoghurt oil mix into it.Mix nicely.Now add grated apple to this mixture.Mix so that no lumps remain.If it does not have drop down consistency, add water to the dry-wet -apple mix to get drop down consistency.Wait for 5 minutes so that all dry mix is saturated.
Line a microwaveable vessel with butter paper.Pour the cake mix into the vessel, on to, the butter paper lining.Microwave for 7-8 minutes.After microwave is witched off test with toothpick.If it comes clean ,cake is ready.If not ,microwave for another minute.Let it remain in microwave for 5-7 minute after switching off.Then take out the cake container & cool outside the microwave for 15-20 minutes.After it is cooled to room temperature,turn the vessel upside down on to a plate.Let it cool for 5-10 minutes.Then cut the cake into desired shapes.
Cake texture was same as carrot cake texture.This only happened as cake batter was left aside for five minutes after mixing .Only after 5 minutes,cake batter was poured into cake vessel & baked.
The cake colour is dark as jaggery sugar is brown powder.The black specks seen in the cake is the garted apple peel.The apple used was quite small.Next time ,I will use a bigger apple.
