In a word? No. Coconut flour is very unique in its properties, and subbing in other flours is rarely if ever successful. I know it is a difficult ingredient to find, so I now test my more recent recipes multiple times with different sets of ingredients, mainstream (like wheat flour) and off the beaten path (like coconut flour). If you want to know about subbing in coconut flour in a specific recipe, please post it on the forum and see if anyone has tried it.
