My mom has a lot of self-control when it comes to eating, especially sweets. So when she told me she had some serious trouble stopping at just one of these, my interest was piqued.
Once again I was motivated to make something by GBBO. Millionaire's shortbread is both simple and complicated at the same time. Ya know, simple in theory and complicated when executing. It was really really tasty though so I'd say everyone should give it a go.
