Chocolate digestive biscuit cake

I just made this cake last night.

It was the grooms cake at the royal wedding actually.

You need
A stick of butter
A bag of milk chocolate chips
A package of digestive biscuits

Melt together butter and chocolate. Crush up the cookies leaving some chunks. Add to chocolate mixture and stir.

Place in a greased pan and press down. Put it in the fridge go harden. Then serve.
