About this recipe:This is sometimes known as meatball cookies. A must in our family at Christmas. Feel free to cut recipe in half. I usually bake about 150 dozen cookies at Xmas time to give away in cookie trays.
Preheat oven to 175 degrees C (350 degrees F). Grease cookie tins. In a medium saucepan over medium heat, combine the butter and milk. Cook until melted, stirring occasionally. Set aside to cool.
In a large bowl, stir together the flour, sugar, cocoa, bicarbonate of soda, cinnamon, nutmeg and cloves. Stir in the milk mixture by hand until the dough is firm and not tacky. Mix in the chocolate chips and walnuts. Roll the dough into 4cm balls and place onto the prepared cookie tins. These cookies do not spread much, so you can place them fairly close together.
Bake for 20 to 25 minutes in the preheated oven, until firm. Remove from baking tins to cool on wire racks. Glaze with a thin sugar icing when cool to preserve freshness.
