    I didn't do slices, I did SLABS!!! Snickers work very well too!  -  29 Jun 2014


    Extremely tasty and worked perfectly first time. I put the mix in the freezer for twenty minutes and this made it much easier to spread into the baking tray as it is quite sticky. Next time I will try rolling it into long sausages and slicing it into individual biscuits which should only need about ten minutes in the oven  -  19 Jan 2014
