make them in a 9 inch round tray.
when they are settled, cut straight across about leaving 2 pieces with one piece equalling 1/3 and the other = 2/3. put the two rounded edges together and from the 2/3 side cut pieces off (you can eat the scraps – e/o knows that there are no calories in the broken pieces) untill you end up with eight candles and the shamash.
use more melted chocolate to “glue” the base to the top. also, if it crumbles at all, use more of the melted chocolate to even out the sides.
