Mix the butter and jaggery powder till it 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 extract 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, baking soda, baking powder and salt to the wet mixture.
Finally add the Funfetti mixture along with 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 30-40 minutes.
Remove the cookie dough from the refrigerator. Line a baking tray with parchment paper.
Preheat oven to 375 degree F.
Take around 1-2 tbsp of dough in your hands, form a ball, and flatten a little. I was able to make 14 cookies with the prepared dough.
(Optional) Using the extra sprinkles and chocolate chips, I sprinkled each cookie with around 2 chocolate chips and 10-15 small Funfetti sprinkles on top and pressed them a little to fix them on top of the cookie. You can skip this step if you want.
Bake the cookies for around 10-12 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 5-10 minutes.
The colorful Funfetti Chocolate Chip Cookies are now ready to be served. Also, these can be stored in an air-tight container. Let the party brighten!
