Idk if anyone else remembers, but Batman canonically carries around Bat-cookies according to the Batman/Scooby-Doo crossover.
I LOVE to think Batman carries them around as snacks for Robin. I love it even more to think he uses said cookies to bribe Robin into good behavior in a similar fashion to Scooby Snacks.
Little Dick Grayson: I don't wanna go to some stupid Gala! U can't make me!
Bruce, in desperation: would u do it for a bat-cookie?
Dick: woah! Bat-shaped! Cool!
Bruce: andddd you can have another one after the party
Dick, mouth full of cookie: okay :)
Bruce, internally: thank fuck a parenting hack that works
Batman: stop! Don't kill him!
Red Hood: and why do I give a fuck what you-
Batman: would u spare his life for a Bat-cookie?
Red Hood:
Red Hood: I'm not a kid anymore-
Batman: they're fresh, look, still warm
Red Hood: ...
Red Hood: this works ONCE. This ONE time. Gimme that damn cookie.
Batman: of course
Red Hood: Fuck I've missed these what the hell does Alfred put in em
Bruce: go to sleep, Tim
Tim: I'm almost done-
Bruce: go to sleep now and you can have a bat-cookie
Tim: a what?
Bruce: a bat-cookie. See? Here, first taste is free. Try it.
Tim: bribery? Really?
Bruce: positive reinforcement
Tim: giving me treats like I'm some kind of dog?
Bruce: try it and then we'll debate the ethics
Tim [eats cookie]:
Tim:
Tim: okay
Bruce: Okay?
Tim: if I promise to sleep a full 8 hours I want two more and a glass of milk
Bruce: u drive a hard bargain but I accept
Dick: aw, c'mon, Damian. One picture. For me, to remember your first day of high school. Do it for a bat-cookie?
Damian: -tt- I've heard of these so-called "bat-cookies" Insulting. I am not a child. I refuse to participate in such an asinine tradition.
Dick: shame. Alfred made animal-friendly ones so you can share with Ace and Batcow. I guess they don't get any treats either, then
Damian: well
Damian: since it would please you so very much, I will overlook this patronizing lapse in judgment
Damian [tries one bite of cookie]:
Damian:
Damian: given Batcows higher food intake requirements, I will require at least a dozen.
Damian [takes another bite]: perhaps two dozen
Duke: you agree I did a good job today?
Bruce: yes? I suppose. Earlier, when you stopped that-
Duke: shut it. Don't care. Cookie me.
Bruce: excuse me?
Duke: I know about the cookies, old man. You've been holding out on me. The cat's out of the bag. I did a good job, I get a cookie. That's how it works, right?
Bruce: uh well
Bruce: that was a long time ago
Bruce: i had to discontinue that method after-
Duke: are you saying I'm not a valid member of this family because I was never Robin?
Bruce: of course you are! But I don't have any on me-
Duke: don't. Lie. To. Me.
Bruce: Okay! Okay. You're right, I'm sorry. Here, take it. Just... do me a favor, and don't go announcing to the whole cave you got-
Duke: YES. MY FIRST BAT-COOKIE! SCORE!
Every batmember in the vicinity: BAT-COOKIES ARE BACK????
Bruce: NO! stay back! Stay back you animals! Alfred! Alfred! It's happening again-
Alfred, sighing: I'll preheat the oven, sir
