To make the giant Rolo you'll need one big bar of chocolate, a whole heap of toffee and two measuring cups, one slightly smaller than the other. First, melt the chocolate. Then, to shape your Rolo, take your small measuring cup, place it upside down inside the big measuring cup. Pour most of the melted chocolate all around it. Then, put it in the freezer to make it hard. Once the chocolate shell is ready, take the toffee and put it in the middle. Pour the rest of the chocolate on top of the toffee. Let your giant Rolo cool in the refrigerator until it hardens.
