The Cauldron Cake was a popular wizarding cake variant. Cauldron Cakes were mass-produced in Pakistan by Qizilbash Quality Confectionary from 1854 onward. They could be bought from the Honeydukes Express trolley on the Hogwarts Express or at Honeydukes Sweetshop in Hogsmeade. Some witches and wizards, like Bathilda Bagshot, made their own homemade batches of Cauldron Cakes.
Sometime during the 1890s, Albus Dumbledore's mother, Kendra Dumbledore, slammed the door in Bathilda Bagshot's face when she came to bring the new neighbours a batch of homemade Cauldron Cakes. This incident was cited in Rita Skeeter's biography of Albus Dumbledore.
Harry Potter bought some Cauldron Cakes, along with every other sweet on the Hogwarts Express food trolley, on his first journey on the Hogwarts Express on 1 September, 1991. He shared his sweets with Ron Weasley, who did not have the money to buy his own.
