Coconut flour
Defatted, dried coconut ground fine — extremely high in fibre, extraordinarily absorbent, and the least substitutable flour in ordinary use.
Also called coconut flour vs almond flour (INTERNATIONAL); coconut powder (INTERNATIONAL) — Not the same thing. Coconut powder usually means dried coconut milk, which is largely fat and sugar rather than defatted fibre.
Coconut flour is what remains after coconut meat has been pressed for its oil and dried. It is mostly fibre, and everything about how it behaves follows from that.
It absorbs water to an extent no other common flour approaches. A formulation built around wheat flour cannot simply have coconut flour put in its place: the mixture seizes into a dry paste, because the fibre takes up far more liquid than the recipe supplies. Substituting it means increasing the liquid substantially and usually increasing the egg as well, which is a reformulation rather than a swap.
It contains no gluten and forms no network. Structure in a coconut-flour bake comes from egg protein setting and from the fibre holding water, so these bakes are typically egg-heavy, dense, and short rather than chewy.
BakeHQ records it as BINDING WATER rather than as supplying hydration, which is the distinction the whole liquid model exists for. Adding coconut flour makes a formulation drier, not wetter, even though nothing was removed.
What changes if it is left out
There is no drop-in replacement in either direction. Almond flour is the other common grain-free flour and behaves almost oppositely — high fat, low fibre, barely absorbent — so swapping one for the other by weight fails in both directions.
Follows from the water-binding function recorded on this ingredient and from almond flour’s own record.

What it does
Binding
The fibre gel holds a mixture together in the absence of gluten — which is why coconut-flour bakes are short and dense rather than chewy.
Competes for water
Hydration
THE CLEAREST CASE IN THE CATALOGUE. Coconut flour absorbs water to an extent nothing else in ordinary baking approaches, so adding it makes a formulation DRIER even though nothing was removed. This is the distinction the liquid model exists for.
