I took some steps from both the recipes & tweaked a little. Here is my recipe.
1 cup whole wheat flour, 1/2 cup maida , 2 tbsps flax seed powder, 1 tbsp apple cider vinegar, 1/2 cup jaggery sugar ( Patanjali brand ) , 1/4 cup oil,1tsp lemon zest, 3 tbsp lemon juice, 1tsp baking powder, 1/2 tsp baking soda, a pinch of salt.
Icing : 2 tbsp lemon juice, 1 cup powdered white sugar .
Method : Preheat oven to 180 degrees centigrade.Line a baking vessel with butter paper. Keepa side.
Add 6-8 tbsps warm water to 3 tbsp flax seed meal .Mix nicely & keep aside.This is the flax seed egg mix.
Mix all dry ingredients ..whole wheat flour, maida, baking powder, baking soda, salt.Mix all these with a spoon or fork or whisk many times over so that they get nicely mixed. This is the dry mix Keep aside.
Mix oil, apple cider vinegar nicely. Add the jaggery sugar to this mix. Some chunks of sugar may have to be broken up & mixed nicely. Add the lemon zest & lemon juice to the mix. Add the flax seed egg mix to this mix. Mix al;l nicely.This is the wet mix.
Make a hole in the dry mix & pour the wet mix into it .Mix both wet & dry mix nicely so that a batter is obtained.If the batter is not getting formed, add some water drop by drop. The batter formed must have idli batter consistency.
Bake in convection mode at 180 degrees centigrade for 45 minutes or till a toothpik inserted in cake comes out clean. I bake in microwave mode for 4-5 minutes after this convection baking to ensure that cake is fully baked.
Take 2 tbsps lemon juice & add 1 cup powdered sugar to it. It will become like a white grainy liquid. Pour this over the cake after the cake has cooled & reached room temperature.The icing got so much that it was poured over the whole cake & so much so that not even a little space of cake was dry .
I should have used just 1 tbsp lemoin juice with 1/2 cup white powdered sugar. Cut the cake into desired shapes & serve.
The cake turned out fluffy, moist& soft. Yet, I found lemon zest wanting. Of course the lemon sugar icing taste makes up somewhat for the lemon zest !
