Preheat oven to 375 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, baking soda, baking powder and salt to the wet mixture.
Finally add the Funfetti mixture 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.
Remove the cookie dough from the refrigerator.
Line a baking tray with parchment paper.
Take around 1-2 tbsp of dough in your hands, form a ball, and flatten a little. I was able to make 13 cookies with the prepared dough.
(Optional) Using the extra 1/2 Tbsp sprinkles, I sprinkled each cookie with 5-10 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 12-15 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 Cookies are now ready to be served. Also, these can be stored in an air-tight container. Let the party begin!
