Preheat the oven to 190 degrees Celsius.
Blend the flour, cocoa, goat's milk powder together with the maple syrup, omega spread sea salt and orange zest in a food processor to form a dough (if the mixture is too hard, add a couple or tablespoons of cold water until it's soft enough to handle).
Using your hand mould them into rounds and place on a lined baking tray. Bake for 20 minutes.
Bring a pan of water with a metal bowl over it to the boil. Break the chocolate into pieces in the bowl and turn the heat off the pan. Stir the chocolate with a wooden spoon until it's completely melted. Dip the top of each biscuit into the chocolate and place a piece of walnut on the top. Set aside to set.
Note: Cocoa is made from de-fatted, pulverized and roasted cacao seeds. It contains antioxidants and naturally occurring plant chemicals which may help lower blood pressure and prevent atherosclerosis.
