The “millionaire” prefix to Millionaire’s Shortbread (Caramel shortbread) equates to the decadence of the sweet treat, an upgrade from shortbread.

Caramel shortbread, also known as caramel squares, caramel slice, millionaire’s shortbread, millionaire’s slice, chocolate caramel shortbread, and Wellington squares is a biscuit confectionery item composed of a rectangular, triangular, or circular shortbread biscuit base topped with caramel and milk chocolate.
