Coconut flour

Coconut flour is one of the many food products made from the fruit of the palm tree Cocos nucifera. Made from dried, ground coconut meat, coconut flour is a natural byproduct of coconut milk production.
Like wheat flour, coconut flour is a white or off-white flour commonly used in baking. Since it doesn't contain gluten, people on gluten-free diets can substitute coconut flour in their recipe for baked goods. 
Although coconut flour can be used as a substitute for wheat flour, many recipes must be adjusted to account for its different composition. Coconut flour is thicker than wheat flour and retains more liquid. Because it is gluten-free, doughs made with coconut flour need to be mixed longer.
