    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
