Millionaire’s Shortbread is also known as caramel shortbread, caramel shortcake, caramel squares, caramel slice, or millionaire’s slice. It is a confection made with layers of a high-fat, unleavened sweetbread, caramelized condensed milk, and dark chocolate. It gets its texture from large amounts of butter. The heated condensed milk gives it a creamy caramel filling, and quality baking chocolate is essential for a soft, rich topping. The treat is prepared in stages, with the bread being baked first, followed by the caramel and then the chocolate. Shortbread evolved from earliest recipes in Elizabethan-era Scotland to its decadent toppings being added in the 19th century.
