I love this recipe as it can be made with any biscuit (cookie) you like. The stronger flavoured ones are best but will work with any. I love the ginger taste in this. We have a biscuit (cookie) that is quite hard and spicy called Ginger Nut, that is what I used here but you can use a chocolate flavoured one too which is called a Choc Ripple Cake. Like I said any biscuit works.
