I remember my mum making this Chocolate Coconut Slice often when I was a kid. The recipe my mum used was originally from a friend of hers and it was made using a butter cake packet mix as the base.
When I got the urge to make it a few years ago I didn’t have mum’s recipe at hand but I found something very similar in one of my Super Food Ideas magazines which made it from scratch and it tasted just like mum used to make.
