Millionaire’s Shortbread Recipe: Caramel Shortbread Baking Tips

Millionaire’s shortbreads are baked in a single [baking pan](https://www.masterclass.com/articles/types-of-baking-pans), then cut into squares or narrow rectangles to serve, but bakers can also assemble them in a mold for easier portioning. 

While the exact origins of this dessert are unconfirmed, one of the earliest mentions of caramel shortbread bars was in a 1970 issue of *The Australian Women’s Weekly*.
Making millionaire’s shortbread requires a little patience as each layer comes together. Consider these tips to finesse the final product: 

1. __Add toppings__. Garnish the chocolate topping with finely chopped nuts like pecans, mini chocolate chips, flaky sea salt, or decorative sprinkles.
