When it goes wrong · Bake
Dense and heavy with a tight crumb.
Can you save it?
Reviewed for this symptom
Not fixable in this bake — the structure set that way. Serve it thin with something moist, or toast slices and treat it as a base. Check the leavening date and mix less next time.
How to confirm the diagnosis
Observable cues, not inferred user state
- A tight, gummy crumb rather than open holes
- The batter was beaten after the flour went in
- The leavening is old or did not fizz
Not this?
- A cake rose and then sank in the middle.
- Dark crust, raw centre.
- Uneven — one side darker every time.
- Cookies spread flat into one thin sheet.
- The cheesecake cracked across the top.
What actually happened
Only this symptom
Overmixed after the flour went in, which developed gluten in something that did not want it, or leavening that was old and inert.
The full mechanism
Shared by every bake failure
In baking, heat is setting a structure rather than cooking something already formed. Several changes happen at once and in order. Gases expand and steam forms, inflating whatever the batter or dough has trapped — most of a cake's rise happens in the first minutes and is oven spring, not leavening acting later. Starch gelatinises from around 60°C, absorbing water and swelling. Egg and gluten proteins coagulate from roughly 70°C and lock the expanded structure in place. Only above about 150°C does the surface brown. Opening the door early drops the temperature and can collapse a structure that has expanded but not yet set — that is the real reason the warning exists, not superstition. Sugar, dairy and egg all brown fast, which is why enriched doughs bake cooler than lean ones.

Prevent this specific failure
Fold the flour in only until no dry streaks remain, and test the baking powder in hot water — it should fizz.
What right looks like
Shared by every bake failure
- A skewer comes out with moist crumbs rather than wet batter — clean and dry usually means slightly overdone.
- The centre springs back when pressed and no longer holds a dent.
- Bread sounds hollow tapped underneath, and reads about 96°C internally if you would rather measure than guess.
- The edges pull very slightly away from the tin, which happens as the structure sets and contracts.
