Anyone who takes the time to make cookies from scratch knows that the type of cookie sheets one uses will determine how your cookies come out and taste delicious.  Since I do all my own baking of cookies, never buy cookies out of the store, I make sure I have the best cookie sheets that money can buy.  Over all the years of baking, I have found that the Insulated Cookie Sheets work the best for me.  The cookies bake evenly & do not burn as easily.,

Insulated cookie sheets are basically two sheets that have been connected around the edges which creates a small pocket of air that cannot escape. The air inside of the pocket heats to the set temperature of the oven when the insulated cookie sheet is placed inside.   I have found that I normally have to bake the cookies a little bit longer on these cookie sheets as appose to the aluminum or non-stick cookie sheets.

There are other types of cookie sheets – Aluminum Cookie Sheets and Non-Stick Cookie Sheets that can be used as well.  Everyone will have their own preference.  For the best results, I suggest that you try the different types of cookie sheets and make your own determination of what works the best.
