Cookie sheet pans with non-stick coatings also have an impact on cookies. When baking cookies on a non-stick cookie sheet pan, the cookies tend to spread more evenly. This can cause a thinner cookie. A thinner cookie may have a different taste and texture compared to a thicker one. For example, sugar cookies baked on a non-stick cookie sheet pan may be more delicate and crispy throughout. Since the non-stick surface allows the cookie dough to spread, the ratio of the ingredients in the cookie changes slightly. The taste can be more pronounced in some ways as the cookie is thinner and the flavors are more concentrated. Also, the non-stick coating can sometimes prevent the cookie from getting a thick, crusty bottom, which gives the cookie a different mouthfeel compared to when baked on a stainless steel or aluminum cookie sheet pan.
