Can you substitute coconut oil for butter in cookies?

When you are looking to replace butter with coconut oil, it can generally be substituted at a 1:1 ratio.  However, when baking you need to be aware that butter gives cookies a different flavor and has a higher water content than coconut oil. 

Therefore, not all cookie recipes allow for coconut oil to perfectly replace butter. It definitely depends on the individual recipe, so it’s best to use a recipe that already calls for coconut oil.  This specific recipe replaces half of the butter with coconut oil which we found to be the perfect balance of using coconut oil in the cookies.
