If making with children, supervise them when they melt the marg, syrup and Mars Bars.
When setting the cake, I put it in the freezer for a short while but keep checking it so it doesn't freeze.
The amount of portions you receive from this cake will depend on how deep you make it and how big you cut your portions.
