1) Preheat oil to 180C.
2) Divide each biscuit into 4 pieces and roll each piece into a ball. Add to hot oil and fry until golden brown. Remove the nuggets to a paper towel lined plate to soak up some of the oil.
3) In a large paper bag combine the cinnamon, nutmeg, ginger, and icing sugar. Add the nuggets to the bag and shake to coat. Place the warm nuggets onto a platter.
4) In a small bowl add the icing sugar and slowly pour in the milk until the glaze is smooth and at the desired consistency. Drizzle the glaze over the nuggets and serve.
