For the Caramel Layer
• Sweetened Condensed Milk – Forms the base of the caramel, adding that irresistible creaminess and sweetness.
• Unsalted Butter – Enhances the richness and ensures a smooth, luscious caramel texture.

Step‑by‑Step Instructions for Millionaire Shortbread
Step 1: Prepare the Pan
Preheat your oven to 325°F (165°C). Line a 9×9 inch baking pan with parchment paper, making sure to leave an overhang for easy removal later. Lightly grease the parchment to ensure the millionare shortbread bars come out easily after baking, and set the pan aside to get started on your crust.
Step 2: Make the Shortbread Crust
In a mixing bowl, cream together room temperature unsalted butter and granulated sugar until the mixture is light and fluffy, about 3-4 minutes. Gradually add all-purpose flour and fine sea salt, mixing until the dough is crumbly. Press the shortbread mixture evenly into the prepared pan and bake for 30-35 minutes, or until the top is just lightly golden. Allow it to cool completely.
Step 3: Make the Caramel Layer
In a saucepan over medium heat, combine sweetened condensed milk, unsalted butter, light corn syrup, and light brown sugar. Stir constantly until the mixture comes to a gentle boil, then let it boil while continuing to stir for about 5 minutes until it thickens. Remove the pan from heat, stir in vanilla extract and fine sea salt, combining well before pouring the luscious caramel layer over the cooled shortbread crust.
Step 4: Chill the Caramel Layer
Cover the pan with plastic wrap or foil and refrigerate for about 30 minutes, allowing the caramel layer to set completely. This brief chill is crucial for achieving that perfect distinct layer between the caramel and the next layer of chocolate in your millionaire shortbread.
Step 5: Add the Chocolate Layer
In a microwave-safe bowl, combine semisweet chocolate and coconut oil. Heat in 30-second increments, stirring in between, until the chocolate is fully melted and smooth. Once melted, pour the rich chocolate mixture over the chilled caramel layer, smoothing it evenly with a spatula. If desired, sprinkle with flaky sea salt to enhance the flavors.
Step 6: Set the Chocolate Layer
Return the pan to the refrigerator and let the millionaire shortbread set for approximately 45 minutes or until the chocolate topping is firm to the touch. This will create the final delectable layer that holds everything together beautifully, making it ready for slicing.
Step 7: Slice & Serve
Once set, lift the bars out of the pan using the parchment overhang. Place them on a cutting board and use a sharp knife to slice into 16 squares. Allow the bars to sit at room temperature for 10-15 minutes for clean edges before serving. Indulge in your homemade millionaire shortbread and delight your guests!

Expert Tips for Millionaire Shortbread
-
Room Temperature Butter: Ensure your butter is soft and at room temperature for perfect creaming, which helps achieve a light texture in the shortbread crust.
-
Constantly Stir Caramel: Stir your caramel mixture constantly as it cooks. Leaving it unattended can lead to burning, ruining the delicious flavor of your Millionaire Shortbread.
-
Chill Layers Properly: Be patient! Chilling your caramel layer for at least 30 minutes is crucial for achieving distinct layers in your bars.
-
Avoid Overbaking: Take your shortbread out of the oven as soon as it turns light golden. Overbaking can result in a hard texture rather than the perfect crumbly base.
-
Use a Hot Knife for Slicing: To get clean cuts, dip your knife in hot water before slicing the bars. This will help maintain the beautiful layers of your Millionaire Shortbread.

Millionaire Shortbread Recipe FAQs
How do I choose the right unsalted butter for the shortbread crust?
Absolutely! For the best results, use high-quality unsalted butter that’s at room temperature. This allows for optimal creaming with the sugar, creating a light, fluffy texture in your shortbread. Look for butter that is pale yellow and does not have any strange smells—it should smell like fresh cream.
What is the best way to store leftover Millionaire Shortbread?
To keep your Millionaire Shortbread fresh, store it in an airtight container at room temperature for up to 3 days. If you prefer it to stay fresh longer, keep it in the fridge for up to 1 week. Make sure to wrap it tightly in plastic wrap to prevent it from drying out.
Can I freeze my Millionaire Shortbread?
Absolutely! To freeze your Millionaire Shortbread, slice the bars into squares first, then wrap each piece tightly in plastic wrap. Place them in a freezer-safe container or bag. They can be stored this way for up to 2 months. When you’re ready to enjoy them, simply thaw in the fridge overnight.
What if my caramel layer doesn’t thicken properly?
If your caramel isn’t thickening as it should, ensure you’re stirring constantly and cooking it at medium heat. If it’s not thick enough after boiling for 5 minutes, return it to the heat for an additional minute or two—just keep stirring! If it still doesn’t thicken, you can try adding a teaspoon of cornstarch mixed with a bit of water to help it set.
Are there any dietary considerations for pets or allergies?
Yes, it’s important to keep in mind that Millionaire Shortbread is not pet-friendly due to ingredients like chocolate and sugar, which can be harmful to animals. For allergies, be cautious with substitutes; ensure you’re using allergy-friendly options, especially with ingredients like butter and chocolate. Always check labels for potential allergens if serving to guests.
How long should I chill the layers between making the Millionaire Shortbread?
After pouring the caramel over the cooled shortbread crust, chill it in the refrigerator for at least 30 minutes to set. Once you’ve added the chocolate layer, return it to the fridge for about 45 minutes. This chilling time is crucial for ensuring that the layers hold together beautifully, enhancing the final presentation of your delicious millionaire shortbread bars.
