It seems the story tends to go like this: A pancake escapes its original maker, and as it makes its getaway, encounters lots of other animals who express their desire to eat it. Not surprisingly, the pancake doesn't grant their request and keeps on running. It isn't until an animal, usually a fox (but sometimes a pig), claims that he doesn't want to eat it, that he is able to trick the pancake into getting into its mouth. So it's a strange, depressing tale that seems to encourage deception, unless you look at it as cleverness, depending on if you have sympathy for a talking pancake. It's that strange tension again that exists in the fairy tale world, in which characters have to eat, but even food has the potential for being anthropomorphized and given its own desires. Yet especially in a world where food was more scarce, you might feel less sympathy for a pancake whose sole purpose is to be eaten, as opposed to animal tales (in which a character might be rewarded for compassion for an animal, and yet also eat meat, sometimes of the same animal!) And although most of the breakfast pastries that are consumed, at least on Ashliman's page, are pancakes or loaves of bread, it also makes sense that the American Gingerbread Boy would be seen as sentient, since he is at least modeled after a human.
And some slightly less related tales: the English "Dathera Dad" is about a fairy child trapped in a pudding. The Russian "Devil in the Dough-Pan" is a warning about the consequences of failing to bless your food while making it, because otherwise a demon can inhabit it-and if you bless it after the demon is there, he'll be trapped! (Although the woman still lost her loaf, it was the demon who regretted entering the bread in the first place).
