Cake
Sweet baked goods built on an aerated batter, where tenderness is achieved by limiting gluten development rather than encouraging it.
What unites the family
Structure comes from egg and starch setting around gas cells that were introduced mechanically or chemically, with gluten development deliberately kept low.
Cake is bread’s opposite, mechanically
Where bread builds a gluten network and ferments gas into it, cake introduces gas first — as air beaten into fat and sugar, as air whipped into eggs, or as carbon dioxide released by a chemical leavener — and then sets a structure around it before the gas escapes.
High sugar and high fat both interfere with gluten formation, which is why cake recipes tolerate, and often require, mixing that would ruin bread. The failure mode is the reverse too: overmixing a cake batter develops enough gluten to make it tough and to cause tunnelling.
Why cakes fail near the end
Most cake faults are set in the oven rather than in the bowl, because the structure is a race. Gas expands and the batter rises before egg proteins coagulate and starch gelatinises enough to hold the shape. If the leavening is too aggressive, or the structure sets too late, the risen batter collapses — which is what a sunken cake usually is.
What is in it
Chocolate cake
A creamed or blended cake containing cocoa solids, whose acidity and starch content change how the batter is leavened and how the crumb sets.
Chemical leaveningMechanical aerationBrownie
A dense chocolate bake positioned deliberately between a cake and a confection, where minimal leavening and high fat prevent an open crumb.
Mechanical aerationMuffin
A chemically leavened quick bread mixed by combining wet and dry ingredients only until just moistened, because further mixing is visibly punished.
Chemical leaveningSponge cake
A cake raised principally by air whisked into egg, which makes it the category where technique matters more than formulation.
Mechanical aerationChemical leaveningBanana bread
A chemically leavened quick bread whose defining ingredient is also the reason it goes wrong — fruit purée is a liquid, and most people do not weigh it.
Chemical leaveningCheesecake
Structurally a baked custard rather than a cake, which is why it cracks instead of sinking and why it is baked gently.
UnleavenedCarrot cake
An oil-based, vegetable-loaded batter cake that behaves nothing like a creamed sponge — moist by construction, and dense for reasons a sponge never has.
Chemical leaveningPound cake
The reference creamed cake: equal weights of the four ingredients, no chemical leavening in its original form, and a crumb that shows every mixing error.
Mechanical aerationChemical leaveningFruit cake
A cake where the batter is a minority ingredient, the fruit is a structural and water problem, and the bake is long, low and slow for reasons that follow from both.
Mechanical aerationChemical leaveningCupcake
A creamed cake in a very small case, where the same batter behaves differently because heat reaches the middle in a fraction of the time.
Mechanical aerationChemical leaveningRed velvet cake
A lightly cocoa’d acidic butter cake whose colour is now added and was once partly chemical — and whose texture claim is about acid, not about the dye.
Chemical leaveningSwiss roll
A thin foam sponge that must be rolled while it is still hot and flexible, because a cooled one has set into the shape it will crack in.
Mechanical aerationAngel food cake
A fat-free egg-white foam cake that depends on an ungreased tin to climb, and is cooled upside down because its own weight would otherwise collapse it.

What goes wrong across the family
Faults the graph attaches to more than one member, which is what makes them characteristic of the family rather than of one product. Each one asks what you can observe before it offers a cause.
It baked unevenly
One part is done and another is not — one side darker, the base burnt, or two trays that came out looking like different recipes.
The cake is dry or crumbly
It falls apart when cut, eats dry, or both — and the three usual causes are distinguishable from the crumb.
The cake domed and cracked on top
Almost always the same story: the surface set into a lid while the middle was still growing.
Cake sank in the middle
The cake rose well and then fell, leaving a dip or a dense band in the centre.
The cake is raw, wet or gummy in the middle
Adding time is the reflex and it frequently makes the cake worse. The question is whether the heat ever reached the middle.
The cake is dense and did not rise
Which aeration mechanism the cake was relying on decides which causes are even possible.

Products in this family
A creamed batter set by egg and starch around mechanically and chemically produced gas.
Chemically leavened and set by egg and starch, though mixed by a method that deliberately avoids the creaming stage.
Placed in the cake family because it is an egg-and-starch batter, though it sits deliberately at the boundary with confectionery and is defined largely by how little it does what cakes do.
The cake family’s reference product.
Named a bread and built like a cake. Filed by method, because the method is what predicts how it behaves.
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.
An oil-based chemically leavened batter set by egg and starch.
The reference creamed batter for the family.
A creamed batter carrying a fruit load heavier than itself.
The family’s standard creamed batter, baked small.
An acidic creamed batter leavened by bicarbonate reacting with buttermilk and vinegar.
A whisked foam sponge — aerated mechanically and set by egg and starch.
A fat-free egg-white foam, which is the family’s aeration mechanism taken to its extreme.

What this product needs done
Aeration
The family's defining requirement: gas introduced BEFORE the bake and a structure set around it, which is the opposite order from bread.
Gas retention
Making the cells is not keeping them. A batter that aerates and cannot hold it collapses in the tin, which is the fault the distinction exists to explain.
