One way to use up leftover icing from store-bought cake mixes.
I've made the family's favourite apple slice a couple of times now but after purchasing two vanilla cake mixes I ended up with unused packets of icing. I asked my Aunt what she did with the icing, only to be told that I could buy vanilla cake mixes without the icing mix!
However, I can't buy a gluten-free cake mix without the icing so I started to investigate gluten-free recipes where I could use the icing. And this was the result: a chocolate carrot and ginger slice.
