I would image that the Caped Crusader probably uses the standard sized Batman Symbol Dog Tags to make cookies though it certainly isn't approved for that for us 'normies'. Hey, we weren't trained by ninjas in the mountains but if you were...feel free to do whatever! The Batman Symbol Dog Tags has a punched-out style that results in the symbol being separated from the rest of the dog tog so it is kinda like some Bat-gadget! Kinda.
