Generally, cookies are baked at 350 degrees F (175 degrees C) for 8 to 12 minutes, depending on the size of the cookie. The cookies in the picture were baked at 375 degrees F (right), 350 degrees F (middle), and 325 degrees F (left) for about the same amount of time; give or take a few seconds. According to Fine Cooking, the higher the temperature, the less your cookie will spread. Why? Because the higher temperature causes the cookies to firm faster (aka set faster) and this prevents spreading. Cookies baked at 375 degrees F will have a thicker, chewier bottom. Baking at 350 degrees F is definitely the best temperature to bake at!
Side Note: After cookies are out of the oven
- For chewy cookies, allow them to cool on the pan for 3 to 5 minutes before transferring to a cooling rack.
- For crisper cookies, let cookies cool for one minute on the baking sheet before transferring to a cooling rack.
