Spread this over the base and place in the fridge to set up while you prepare the topping., For the topping, melt the chocolate and butter in the top of a double boiler. Spread this over the cooled filling and place in the fridge for a few minutes to set up a little., Score the chocolate to make it easy to cut into squares when you serve it.
