Method

1. Combine icing sugar and milk in a bowl. Tint with food colouring to make dark grey. Dip one-half of each donut into the icing, spreading to coat evenly. Place on a wire rack.
2. Decorate donuts with eyes. Cut 24 small triangles from strawberry sour strap and arrange on donuts to make fangs. Cut 24 small triangles from 1 liquorice strap and arrange on the donuts to make ears.
3. Cut 24 wing shapes from liquorice straps. Use a small knife to make a small slit on either side of each donut. Insert a toothpick in each cut. Arrange wings over toothpicks, pressing into the donuts to secure. Arrange on a serving plate and remove toothpicks before eating.
