Preheat oven to 350 degree F.
Meanwhile, mix the butter and unrefined cane sugar till the sugar 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 to this mixture.
Now add vanilla essence to the above mixture and stir till all the ingredients are uniformly mixed. The wet ingredients mixture is now ready.
For the dry ingredients, mix in whole wheat flour, cocoa powder, baking soda, baking powder and salt to the wet mixture.
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 10-15 minutes.
Line a baking tray with parchment paper. Take around 2-3 tbsp of cookie dough and roll into a ball. Then flatten the dough ball (lightly press, we don't flatten this too much, as the cookie expands while baking) and place on the baking tray. I was able to make 14 cookies with the prepared dough.
Bake the cookies for 12-18 minutes in the preheated oven, or till you see creases on top of the cookies. The cookies will be soft to touch, but once cooled, they will be fine.
Remove the cookies from the oven, and allow them to cool for at least 10-15 minutes.
The whole wheat double chocolate chip cookies are now ready to be served warm or these can be stored in an air-tight container!! I refrigerated the cookies for around an hour to stiffen up the gooey consistency of the warm cookies before storing them at room temperature.
