You can make these nut free by leaving out the macadamias, or replacing them with dried fruit etc. You can also substitute the spelt flour for normal plain flour. I use Enjoy Life Foods mini choc chips as they are a healthy alternative to store bought chocolate: containing only evaporated cane juice, natural chocolate liquor (non-alcoholic) and non-dairy cocoa butter.
