The Millionaire Caramel is a bit of a labour of love. Our bakery manager, Rachel, is the queen of caramel, mostly because she is endlessly patient and doesn’t get frustrated by all the stirring. She makes the most perfect caramel every time. That said, the joy of cutting a slice of Millionaire Shortbread with perfectly thick caramel is worth all the stirring, we promise. And it tastes fantastic.
