Cauldron Cakes from Harry Potter
Chocolate cauldron cakes from the Harry Potter universe: a moist sponge with a creamy filling and chocolate glaze, like from the Hogwarts Express sweet trolley.
Cauldron cakes are one of the treats sold by the trolley witch on the Hogwarts Express, alongside chocolate frogs and Every Flavour Beans. The books leave their exact form a mystery, so fans invented their own: chocolate cauldron-shaped cakes with a creamy filling and a glossy glaze. This is our recipe for that magical treat — no rare ingredients, and it looks great at a themed party.

❓ Frequently asked questions
What are cauldron cakes in Harry Potter?
Cauldron cakes are a sweet sold by the trolley witch on the Hogwarts Express alongside chocolate frogs. The books never describe their exact look, so our recipe is a popular fan version of a cauldron-shaped chocolate cake.
How do I make the cauldron shape more pronounced?
Use straight, tall muffin molds or silicone half-sphere molds. Glaze dripping down the sides boosts the cauldron effect.
How long do these cakes keep?
With the cream filling, keep them refrigerated and eat within 2 days. Without filling, the sponge keeps 3–4 days.
