A cookie jar is just that: a countertop container of coveted confectionery crisps. But in old-fashioned Dom Coms, it plays a role as an appealing but unhealthy Forbidden Fruit. Trying to make an unauthorized raid for the cache of sweets is a stock act of misbehavior for Little Jimmy, especially if he's a Pint-Sized Kid and needs to account for the extra step of reaching the countertop (or worse, the top of the fridge) in a way that won't get noticed. Oftentimes, the offense is treated as a Felony Misdemeanor.

- One interstitial for Jimmy Neutron: Boy Genius sees Jimmy getting caught trying to raid the cookie jar.

- Rugrats naturally features this. Oftentimes, the babies will form a Human Ladder to reach it:

- In "Cavebabies", Angelica wants to eat cookies for dinner, but Didi tells Angelica she can't have any cookies until she finishes her spinach.
