I don't know that much about Dr Who, but I do know one thing for sure, the Tardis is much larger on the inside than it appears on the outside. This is probably a good thing as you wouldn't have to refill this cookie jar too often. Also because it's a time machine, you don't have to worry about your cookies getting stale. Or it could be that you always have stale cookies, or both. Time travel makes for difficult problems when it comes to food freshness.
