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.
Better with butter. Top with melted Mars bar too, instead of ordiniary chocolate. Simply delicious. - 26 Sep 2011
Excellent. Great fun for teenagers to make and eat!!! The mars bars can be swapped with double deckers for a slightly different taste....just as popular. - 24 Sep 2012
A very easy recipe to make and was very well received by all the family. Lots of chocolate Mars gooey-ness. Perfect for packed lunches. Yum! For the 'icing' I melted another Mars bar along with the plain chocolate. Thanks for sharing - 29 Apr 2012
