Cheesecake
Structurally a baked custard rather than a cake, which is why it cracks instead of sinking and why it is baked gently.
Also called baked cheesecake (INTERNATIONAL), new york cheesecake (US), vanilla cheesecake (INTERNATIONAL)
A baked cheesecake is a custard. Its structure comes from egg protein coagulating around fat and moisture, not from a flour network holding gas, and almost everything that distinguishes it from a cake follows from that.
IT IS NOT LEAVENED. Any rise during baking is expansion, and a cheesecake that puffs dramatically has been baked too hot and will fall as it cools. A cake that sinks has lost a structure it built; a cheesecake that sinks never had one to lose, and the flat result is normal rather than a fault.
IT CRACKS RATHER THAN SINKING, and for a reason that is the same as the cracked-cake mechanism seen from the other side: the surface sets and dries while the interior is still expanding, and a set custard has no extensibility at all. Cracking is therefore a heat-management fault, which is why cheesecake is baked low, often in a water bath, and often cooled slowly in the turned-off oven.
EGG PROTEIN OVERCOOKS WITHIN A NARROW RANGE. Past the point of setting it contracts and squeezes out moisture, giving the grainy, weeping texture that is the characteristic overbaked cheesecake fault. The centre should still move when the tin is nudged when it comes out; it finishes setting as it cools.
Unbaked or set cheesecakes are a different product using a different mechanism — gelatine or simply chilled fat — and BakeHQ does not treat the two as variants of one thing.
What it should be like
- Structure
- Dense, smooth, uniformly set — no crumb
- Tenderness
- Soft and yielding, never springy
- Crust
- Pale and level; browning is usually a fault
How it keeps
Requires refrigeration, and that is a food-safety requirement rather than a quality preference — it is a set egg-and-dairy custard. Refrigeration also firms it, which is why it slices cleanly cold and why the texture is judged after chilling rather than on the day it is baked.
Universal professional and domestic practice with an obvious mechanism. BakeHQ states no times or temperatures and defers to the relevant food-safety authority for anything beyond the direction, which is a standing editorial rule for safety-bearing content.

Where it comes from
Professional consensus
Agreed by professional bakers and baking-science texts, with an accepted mechanism, though not isolated by controlled experiment.
Baked and unbaked cheese-set desserts exist independently across Europe and North America, and the differences between the New York, German and Basque forms are structural rather than decorative.

Where cheesecake sits in the cake taxonomy
BakeHQ sorts cakes by how the air gets in, and cheesecake is the family where the honest answer is that it does not.
It is recorded as a custard-set cake because that is where readers look for it and because the classification is pragmatic rather than scientific — culinary categories overlap and no formal standard governs them. Structurally it has more in common with a baked custard or a quiche filling than with a sponge.
Stating that plainly is more useful than forcing it into a cake family it does not behave like. It is also why the cake fault models ask which family a cake belongs to before offering causes: nothing that goes wrong with a creamed cake can go wrong with this.

Part of
A pragmatic placement rather than a structural one. It is set by egg protein rather than by a flour network holding gas, which the record states plainly.
What this product needs done
Structure building
The whole of its structure. Egg protein setting around fat and moisture, with no flour network and nothing holding gas.
Emulsification
Egg yolk holding a great deal of fat and water together. A broken emulsion is the route to a grainy set.
Hydration
A pourable batter whose water is largely carried in the soft cheese rather than added separately.
Techniques this product depends on
Gentle, even heat is the requirement. Egg protein overcooks within a narrow range, and a water bath is how the edge is kept from setting long before the centre.
Characteristic ingredients
The structure. Everything else is flavour and texture around a set custard.
Things that go wrong
The cake domed and cracked on top
Cheesecake cracks where a cake would sink, because a set custard has no extensibility left when the surface dries.
The cake is raw, wet or gummy in the middle
A wet centre in a cheesecake is usually correct on removal and set on cooling, which the model needs to say.
