Black Forest Traybake

I use jam in place of the traditional sugar in this traybake, which makes it slightly fudgy in texture. It may need a little longer to cook depending on which jam you use – generally the fancier the jam, the higher the fruit content, so it takes a little longer to cook through. Low-sugar and sugar-free jams are very tricky to make work here, when I tested them the finished result was more like a sloppy brownie than a traybake, which isn’t a bad thing, just not what I was going for!
