Macadamias are high in unsaturated fatty acids and also palmitoleic acids, which actually helps to speed up metabolism and lowers cholesterol. They are an excellent source of minerals such as calcium, iron, magnesium, manganese and zinc as well as being rich in vitamins, especially the many B-complex vitamins.
The nuts are quite oily and fatty, so a little goes a long way. These are a delicious treat, and so easy to make.
You can get quite creative with the cookies, add chocolate chips, other dried fruits, seeds if you wish to make it less sweet. The oils in the nuts will help hold the cookies together nicely and a quick 10 mins in the oven helps set them so they are a bit crunchy on the outside while soft and chewy on the inside.
