How do you make cookies that cook all the way through and burnt on edges?

To make cookies that cook all the way through and burnt on edges, you can do the following:

- Preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius) and make sure the oven is fully preheated before baking the cookies.

- Use thin cookie sheets instead of thick ones. The thicker the cookies sheet the longer it takes for the heat to reach the cookie dough and could result in burnt edges and uncooked dough in the center of the cookie.

- Do not overcrowd the cookie sheets to allow even heat circulation and prevent the cookies from spreading into other cookies which could result in uneven baking.

- Bake the cookies at a lower temperature for a longer period of time. Reduce the oven temperature by 25-50 degrees Fahrenheit (10-30 degrees Celsius) and increase the baking time accordingly.

- Check the cookies regularly after 80% of the suggested bake time on the recipe to prevent overcooking.

- For a thicker cookie it may be necessary to move them to the lower rack at the 50% mark of baking.

- Place the cookies on a cooling rack immediately after removing them from the oven to prevent carryover cooking and allow the cookies to finish baking as they cool.

- Let the cookies cool completely before storing or serving.
