Preheat oven to 375 degree F.
Meanwhile, mix the butter and the jaggery powder till you see a smooth blend. I prefer to mix by hand, since I don't use a mixer. Because we are not using completely melted butter, so a whisk or spatula is not helpful in this case.
Add in the egg to this mixture. Stir till you see a uniform mixture of ingredients.
Now add vanilla essence to the above mixture. The wet ingredients mixture is now ready.
For the dry ingredients, add whole wheat flour, finger millet flour (ragi), baking soda, baking powder, salt and cocoa powder to the wet mixture.
Finally add Nutella and give it a good mix with hand. The dough will be a little loose at this stage, so it is advisable to put the dough in the fridge for at least 5-10 minutes.
Line a baking tray with parchment paper. Take around 2 tbsp of cookie dough and roll into a ball. Then flatten the dough ball and place on the baking tray. I was able to make 13 cookies with the prepared dough.
Bake the cookies for 10 minutes in the preheated oven.
Remove the cookies from the oven, and allow them to cool for at least 5-10 minutes.
The whole wheat and ragi chocolate cookies are now ready to be served warm or these can be stored in an air-tight container!!
