This is due to the inability of lauric fats to recrystallize with nonlauric fats. The migration of liquid oils can solubilize some of the fats in the coating. Their chemical incompatibility causes a eutectic effect, and they are unable to fully recrystallize, creating softening in the coating (4,5). This can be overcome or minimized using similar or like fats in the coating and baked item, as well as by increasing the solid-fat content of the fat in the baked item.
