I almost never write a review. But these cookie sheets are so amazing that I felt I really needed to write a review on them. I have been baking cookies since I was eight years old and always found it frustrating that some cookies would burn while others on the same sheet would still be underdone. I finally decided to pony up the cash and invest in quality cookie sheets. I am beyond thrilled that I did! The first batch of cookies I baked on my new Vollrath sheets came out perfectly! That's right -- each and every cookie was perfect! Browned slightly on the edges, golden on the top and bottom, plump in the middle -- you baking afficianados know exactly what I am talking about. I will never use another cheap cookie sheet again. If you love baking like I do then purchase these cookie sheets. You will never bake a burnt, uneven batch of cookies again.
