Preheat oven to 375 degree F.
Meanwhile, mix the butter and the jaggery powder till the jaggery powder is completely blended with the butter. I prefer to mix by hand since I don't use mixer. Whisk or spatula is not helpful in this case, since the butter is not in a completely melted state.
Add in the egg and vanilla essence to this mixture and stir till all the ingredients are uniformly mixed.
The wet ingredients mixture is now ready.
For the dry ingredients, add whole wheat flour, finger millet flour (Ragi), oatmeal, baking soda, baking powder and salt to the wet ingredients and mix everything together.
Finally add the chocolate chips 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 20-30 minutes.
Line a baking tray with parchment paper. Take around 1-2 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 16 cookies with the prepared dough.
Once the oven is preheated, bake the cookies for 12-15 minutes (Mine got baked properly in 15 minutes).
Remove the cookies from the oven, and allow them to cool for at least 5-10 minutes.
Enjoy the Finger Millet (Ragi) Oatmeal Whole Wheat Chocolate Chip Cookies warm just out of the oven or these can be stored in an air-tight container for around 1-2 weeks!!
