Millionaire's shortbread or caramel shortbread is a classic Scottish dessert and one of the country's favorite treats whose main appeal lies in its different textures: the crumbly shortcake base, soft caramel in the middle, and the crisp chocolate top.

For the best millionaires' shortbread, a sprinkle of unrefined sea salt can be added to the sweet caramel as it brings out its creamy richness and at the same time complements the pure, smooth dark chocolate.
