Ingredients You’ll Need

These ingredients work beautifully together, building flavor layer by layer. I recommend using good-quality chocolate and real butter—the difference is worth it. If you can find Lyle’s Golden Syrup, it adds that authentic caramel richness, but I’ll share alternatives below!

• Butter: Real butter gives the shortbread and caramel base that irresistible richness and crumbly texture.
• Sugar: Granulated sugar melts into the caramel, so patience during cooking is key for that perfect golden color.
• Lyle’s Golden Syrup: This classic syrup adds a deep, buttery flavor that’s traditional in millionaire’s shortbread—but if you can’t find it, light corn syrup or honey works in a pinch.
• Condensed Milk: Sweet and creamy, condensed milk is essential for that gooey caramel layer that’s the star of the show.
• Chocolate (dark or milk): Choose a chocolate you enjoy eating on its own—the better the chocolate, the better the finish! I usually go dark, but milk chocolate makes it sweeter and creamier.

Variations

I like to mix things up with this Millionaire’s Shortbread Bars Recipe depending on my mood or the occasion. You’ll find that small tweaks make a big impact and keep this classic fresh and exciting.

• Salted Caramel: Adding a pinch of flaky sea salt on top of the chocolate before it sets gives a delightful sweet-salty contrast that my family goes crazy for.
• Nutty Addition: Toasted pecans or almonds sprinkled over the caramel add a lovely crunch and a toasty depth that I discovered when wanting a little texture contrast.
• Dairy-Free Version: Swap butter for coconut oil and use dairy-free condensed milk—just know the texture might be a little different but still delicious.
• Chocolate Variations: Try white chocolate or swirl milk and dark chocolate for a beautiful marbled effect that’s stunning for gifts or parties.

How to Make Millionaire’s Shortbread Bars Recipe

Step 1: Bake the Perfect Shortbread Base

Start by preparing your favorite shortbread recipe (I’ve included my tried-and-true version in the printable card). Press the dough evenly into your baking pan, then lightly prick the surface with a fork—this prevents puffing during baking. Pop it in your preheated oven at 350º F (170º C) and bake for about 20 minutes until it’s lightly golden and firm to the touch. Set it aside and let it cool completely before moving on. This step is crucial because pouring caramel on warm shortbread can melt your layers together, and we don’t want that!

Step 2: Cook the Caramel Layer to Gooey Perfection

In a heavy-bottomed pan, combine butter, sugar, Lyle’s Golden Syrup, and condensed milk. Bring the mixture to a gentle boil, then reduce heat and simmer while stirring constantly. This part requires your full attention—caramel can burn quickly! I like using a candy thermometer here and bring it up to the “soft ball” stage, about 235-240ºF (113-115ºC). No thermometer? No worries—just drop a spoonful in cold water, and if it forms a soft, pliable ball when you roll it between your fingers, you’re golden. Once your caramel reaches this stage, pour it over the cooled shortbread and spread it evenly. Let it cool to set—this usually takes about 1-2 hours at room temperature.

Step 3: Top with a Smooth Chocolate Layer

Now for the best part! Gently melt your chocolate—my favorite trick is to microwave it on the defrost setting in short bursts, stirring between each so it melts evenly without burning. Pour the melted chocolate over the set caramel and spread it carefully with a spatula to create a smooth, glossy finish. Pop the bars in the refrigerator for at least 30 minutes to let the chocolate harden properly before slicing.

Step 4: Slice and Store Your Millionaire’s Shortbread Bars

Once chilled, remove from the fridge and slice into bars or squares—the sharper your knife, the cleaner the cuts! I always wipe the knife between slices to keep the edges tidy. Store your bars in an airtight container at room temperature or in the fridge if it’s warm. These bars are delicious when freshly made but actually taste even better the next day once the flavors meld together.

How to Serve Millionaire’s Shortbread Bars Recipe

Garnishes

When I want to dress these bars up a bit, I sprinkle them with a few flakes of sea salt or finely chopped toasted nuts before the chocolate sets. It adds a little extra texture and flavor dimension that just elevates the whole experience. Sometimes, a light dusting of cocoa powder on top creates a lovely contrast, especially if you use milk chocolate.

Side Dishes

These decadent bars pair insanely well with a hot cup of strong coffee or a creamy latte—perfect for afternoon tea or coffee breaks. If you’re serving them as part of a dessert spread, fresh berries or a scoop of vanilla ice cream complement their richness wonderfully.

Creative Ways to Present

For special occasions, I like placing the Millionaire’s Shortbread Bars on a tiered dessert stand with some fresh mint leaves scattered around. Wrapping individual bars in parchment paper tied with twine makes them charming party favors or gifts. If you’re feeling extra festive, drizzle contrasting white chocolate over the top in a zig-zag pattern before chilling for a beautiful finish.

Make Ahead and Storage

Storing Leftovers

Lucky for you, Millionaire’s Shortbread Bars keep really well! I store mine in an airtight tin at room temperature when it’s cool, but during warmer months, the fridge helps keep the chocolate from melting. Just bring the bars back to room temp before serving for the best texture and flavor.

Freezing

I’ve frozen these bars a couple of times, and they thaw beautifully. Wrap individual slices tightly in plastic wrap and place them in an airtight container or freezer bag. When you want a treat, just let them thaw in the fridge overnight, and you’ll have a fresh-tasting dessert ready to enjoy.

Reheating

Since these bars are best enjoyed cool, I don’t recommend reheating them. However, if you prefer softer caramel, leaving them at room temperature for 15-20 minutes brings the layers to that perfect melt-in-your-mouth consistency.
