Millionaire’s Shortbread: Layered Dessert Perfection
Millionaire’s Shortbread is a classic, decadent treat beloved for its three distinct layers: a crisp, buttery shortbread base, a chewy caramel filling, and a glossy dark chocolate ganache, all finished with a sprinkle of flaky sea salt. Whether served at a holiday party, baked for a cozy afternoon, or cut into petite bites for a chic gathering, this bar delivers sublime flavor and texture in each bite.
What Is Millionaire’s Shortbread?
These triple-layer bars blend the appeal of classic European shortbread cookies with the decadent chew of homemade caramel and a rich, velvety layer of chocolate ganache. The name “millionaire’s shortbread” refers to the richness—these bars are as luxurious and impressive as their moniker suggests.
Because of their layered format, each component adds its own unique texture and taste:
- Shortbread Base: Crisp and buttery, with a subtle sweetness and slight saltiness that perfectly supports the toppings.
- Caramel Layer: Chewy, luscious caramel that combines sweetened condensed milk, sugar, and butter for deep flavor.
- Chocolate Ganache: Silky, bittersweet chocolate melded with cream for a smooth finish, topped with sea salt to balance sweetness.
These classic bars are often seen in British and American baking, bringing together simple pantry ingredients for extraordinary results.
Ingredient Guide: What You’ll Need
| Component | Key Ingredients | Pro Tips |
|---|---|---|
| Shortbread | All-purpose flour, sugar, cornstarch, salt, melted butter | Use melted butter for even distribution. Cornstarch aids tenderness. Don’t overwork dough. |
| Caramel filling | Sweetened condensed milk, brown sugar, butter, corn syrup, cream, salt, vanilla | Cook slowly and stir constantly; target temperature is 235°F for proper set. |
| Chocolate ganache | Semi-sweet or dark chocolate, cream, neutral oil | Microwave in bursts and stir until smooth. Oil gives shine, flaky salt enhances flavor. |
Other essentials: Heavy-duty pan (metal preferred), foil or parchment for lining, spatula or spoon for spreading, and quality sea salt for finishing.
Step-by-Step Recipe Instructions
Step 1: Prepare the Shortbread Base
- Preheat oven to 350°F. Line a 13-by-9-inch pan with foil, letting the edges hang over for easy lifting later.
- In a large bowl, combine flour, sugar, cornstarch, and salt. Pour in melted butter and stir until a crumbly dough forms. (Don’t overmix to avoid toughening.)
- Press dough evenly into the prepared pan.
- Bake for 25-30 minutes until lightly golden. Transfer to a wire rack and cool for 15 minutes.
Step 2: Make the Chewy Caramel Filling
- In a medium saucepan, combine sweetened condensed milk, brown sugar, butter, corn syrup, cream, and salt. Stir together thoroughly.
- Cook over medium heat, stirring frequently, until mixture thickens, darkens, and begins to pull away from pan sides. Use a thermometer to check for 235°F—this ensures proper set and chewiness.
- Remove from heat, stir in vanilla, and pour immediately over the cooled shortbread crust. Smooth with a spatula.
- Allow to cool completely (about 1 hour) so layers don’t merge.
Step 3: Prepare the Chocolate Ganache
- Combine chocolate, cream, and a small amount of oil in a glass measuring cup.
- Microwave at 50% power in 15-second bursts, stirring after each, until chocolate is melted and silky smooth (about 1 minute total).
- Pour over cooled caramel layer and spread to edges with an offset spatula.
- Sprinkle with flaky sea salt for a finishing touch.
Step 4: Chill and Slice
- Chill bars in refrigerator for 30 minutes to 1 hour, or until set.
- Use the foil edges to lift the entire block from the pan. Slice as desired for bars, squares, or bites.
Expert Tips for Perfection—Texture, Flavor & Appearance
- Pan prep: Use a heavy-duty metal pan for best shortbread texture; glass pans may require longer baking and produce less crisp crusts.
- Use a thermometer for caramel: Target 235°F for ideal chew; heating too little yields runny caramel, overcooking causes hardness and bitterness.
- Patience is key: Let each layer cool fully before proceeding to the next step to ensure clean, distinct stripes and avoid bleeding.
- Slice with a hot knife: Dip a sharp knife in hot water and wipe dry between cuts for clean, professional-looking bars.
- Flaky salt: Don’t skip the final sprinkle! It accentuates flavor and balances sweetness, giving the bars a gourmet finish.

Ingredient Substitutions and Variations

- Extras: Add a layer of chopped toasted pecans or hazelnuts between caramel and chocolate layers for crunch.
Storage, Make-Ahead Tips, and Serving Ideas
- Make ahead: Bars can be made several days in advance and stored, tightly covered, at room temperature for up to 3 days, or refrigerated for up to a week.
- Freezing: Millionaire’s shortbread freezes well for up to 2 months. Thaw overnight in fridge before serving; slice after thawing for best texture.

- Presentation: Try drizzling white chocolate for contrast, or sprinkle with crushed pistachios or dried fruit.
Frequently Asked Questions (FAQ)
What makes Millionaire’s Shortbread different from regular shortbread?
The key difference is in the triple-layer format: classic shortbread is just the base, while Millionaire’s Shortbread adds a rich caramel layer and a glossy chocolate topping, making it richer and more complex.
Can I substitute evaporated milk for sweetened condensed milk in the caramel?
No. Evaporated milk is unsweetened and will not produce the correct texture or flavor for the caramel. Sweetened condensed milk is essential for both sweetness and thickness.
Why does my shortbread crumble or crack when sliced?
Possible reasons include overworking the dough, underbaking, or using too little fat. Aim for a crumbly but cohesive dough, bake until golden, and slice with a hot knife for clean cuts.
How can I prevent my caramel from being grainy?
Ensure all sugar dissolves completely before caramel boils, stir continuously, and avoid overcooking. Using a thermometer can help guarantee the right consistency.
Is flaky salt necessary on top?
Though optional, a sprinkle of flaky salt enhances flavor, balances the sweetness, and adds visual appeal—most bakers agree it’s a non-negotiable finishing touch.
