Made a duplicate copy of each letter layer, then merged the duplicates created. Then made two more copies of the merged layer. Now have 3 layers named alltogether Top, Alltogether Middle, and Altogether Bottom.
I colored the cookie top for now for a visual reference. For middle layer (white)while move tool selected I alternated pressing the down arrow then the right arrow until the middle layer was about the size I wanted it. This created 10 layers, when done I merged the 10 middle layers.
Same procedure as above for the bottom layer except don't start using the alt key until you have down/right arrowed to the bottom of the previous layer, then hold down the Alt key while down/right arrowing while watching for the size you want for the bottom of the cookie.
