Millionaire’s Shortbread Recipe
Millionaire’s Shortbread, also known as Caramel Shortbread and Caramel Squares consists of a biscuit base topped with caramel and milk chocolate.
The biscuit base is a crumbly, buttery, melt-in-your-mouth Scottish shortbread.
Top that with soft, gooey caramel, and a layer of milk chocolate and you have some totally irresistible bars!
The Millionaire’s Shortbread name comes from the fact that these bars are incredibly rich, which is so very true.
Ingredients you’ll need
Here’s a list of ingredients you’ll need to make these millionaire bars. You can find my recipe card at the bottom of this post for the complete list with their amounts.
For the Shortbread:
- Plain/all-purpose flour
- Cornflour/cornstarch: Makes for soft, melt-in-your-mouth shortbread.
- Caster/granulated sugar
- Unsalted butter: Cubed and softened to room temperature.
For the Caramel:
- Unsalted butter: Cubed.
- Light brown sugar
- Sweetened condensed milk
For the Topping:
- Milk chocolate: Good quality, coarsely chopped.
- Double/heavy cream
- Sea salt: For sprinkling, optional.
How to make Millionaire’s Shortbread
To make these bars, simply grab a large mixing bowl and whisk together the flour, cornflour, and sugar.
Add the butter and, using a pastry cutter, fork, or your fingertips, work it into the mixture until it resembles coarse breadcrumbs.
Press the mixture firmly into the bottom of an 8×8-inch square baking pan lined with parchment paper.
Bake for 25 – 30 minutes or until very lightly browned on top. Set aside to cool whilst preparing the caramel.
Add the butter and sugar to a large saucepan over medium heat. Stir until melted and combined.
Add the condensed milk and bring to the boil, stirring continuously.
Cook until the mixture turns a rich caramel colour, has thickened, and is pulling away from the sides – about 5 – 6 minutes.
TIP: If using a candy thermometer, cook until the caramel reaches 107C / 225F.
Pour the caramel over the shortbread layer, and leave to set completely in the fridge.
Add the chocolate and cream to a microwave-safe bowl and heat in 20 second intervals, stirring after each one, until melted and smooth.
Pour over the caramel layer and spread out evenly. If desired, sprinkle with sea salt.
Refrigerate until the chocolate has set completely before slicing into bars.

NOTE: For best results, I highly recommend using the gram measurements (with a digital scale), rather than the cup measurements.
Cup measurements are simply not accurate enough, and I cannot guarantee the best results if you use them.
