These are made using Milk Arrowroot Biscuits. Chosen, obviously, because they are oval/egg shaped. If you’ve never seen, nor heard of, a Milk Arrowroot, you are clearly not reading this in Australia! But hopefully oval shaped, plain biscuits or cookies are available in your area.
The decorations featured are ‘Sour Straps’ and ‘Mini M&Ms’. However, most supermarkets will have a dazzling array of confectionary to chose from.
