Preheat the Oven to 180 degrees.
In a bowl mix together the Sugar, Butter and Egg.
Add Whole Wheat and Ragi flour and mix.
Add vanilla extract, baking soda, baking powder, salt and dark chocolate powder.
Mix well to make a soft dough. Add a little milk if needed.
Make small balls and place on the cookie tray lined with parchment paper. Lightly press the cookies to flatten a little.
Bake in the preheated oven at 180 degrees for 10-12 minutes or until you see cracks on the cookie.
Once out of the oven, let the cookies cool slightly and top with chocolate chips, M&M or any toppings of your choice.
