Kylie Jenner's cookie recipe is a closely guarded secret, but we can give you a few tips to help you recreate her famous cookies at home. For starters, Kylie uses a quality chocolate chip like Ghirardelli or Guittard. She also adds a pinch of salt to the dough to really bring out the flavor of the chocolate. As for the baking process, Kylie recommends using a convection oven set to 350 degrees Fahrenheit. This will ensure that your cookies are evenly baked and come out perfectly crisp. Finally, be sure to let your cookies cool completely before serving - they're even better when they're warm from the oven!
