Hedgehogs are simple, unbaked biscuits that have been around for generations: an Australian classic! And a great lunchbox, snack and afternoon tea favourite! Hedgehogs can be made with or without nuts. If omitting the nuts, use 1/2 cup extra of the biscuits. As an alternative, you can use almonds or walnuts.
