While the precise origins of the millionaire’s shortbread remain somewhat elusive, evidence suggests this decadent treat has been around since at least 1965 and is believed to have Scottish roots. The dessert showcases three distinct yet complementary layers: a rich shortbread base, a luscious caramel filling, and a delicate chocolate ganache, culminating in a treat that could easily justify its name.
Our adaptation of this lavish chocolate caramel shortbread bars employs several clever techniques designed to optimize flavor and ensure consistent results. The first step involves toasting a portion of the flour prior to mixing it into the shortbread dough. This technique imparts a deeper flavor profile, introducing subtle nutty notes that enhance the overall richness of the base. In crafting the caramel, aim for a deep amber hue; combining the sugar with condensed milk at this stage yields a beautifully creamy texture that can be achieved without relying on a candy thermometer. Including a bit of butter in the chocolate topping contributes to a glossy finish, enhancing the visual appeal.
Timing is crucial when layering the components. It’s essential to allow the shortbread crust to cool completely before applying the hot salted caramel; the warmth ensures that the caramel adheres securely to the shortbread. After pouring the caramel, it should be allowed to cool slightly before adding the melted dark chocolate, preventing the layers from combining. To determine if the caramel is set properly, perform a simple test—if it feels firm yet slightly sticky when poked, you’re ready to top it with chocolate.
