Role in series
They are first seen when SpongeBob goes to his grandma's house to receive gifts and it is revealed that he absolutely loves her cookies. He also dips them in milk sometimes and licks the cookie dough off the spoon.
Later in the episode, when SpongeBob chooses to act like an adult, Patrick decides to take SpongeBob's place as the child his grandma feeds these cookies to, and he loves them as much as his best friend does. SpongeBob becomes jealous and wants affection from his grandmother again and for her to feed him cookies, which she does after telling him he does not have to act like a grown-up no matter what others say.
SpongeBob runs into his grandma's house to warn her that BlackJack is out of prison. He does not find her at first, but sees a plate of gingerbread cookies she left on the table, and thinks that BlackJack made her into the cookies. However, his grandma appears and offers the cookies to him. SpongeBob runs off again to seek help elsewhere.
Patrick wears a special hat to eat them in "Grandma's Kisses."
