Step‑by‑Step Instructions for Millionaire’s Shortbread
Step 1: Preheat and Prepare the Pan
Begin by preheating your oven to 350°F (175°C). While it's heating, take an 8×8-inch square pan and line it with parchment paper, ensuring some overhang for easy removal later. This small step will make your life easier when it’s time to slice the finished Millionaire’s Shortbread.
Step 2: Cream the Shortbread Ingredients
In a mixing bowl, combine 1 cup of softened unsalted butter and 0.5 cup of granulated sugar. Using an electric mixer, cream these ingredients together on medium speed until the mixture appears light and fluffy, which should take about 3–4 minutes. This creates a rich base for your shortbread layer.
Step 3: Form the Shortbread Dough
Once your butter and sugar are creamed, add in 2 cups of all-purpose flour, 0.25 teaspoon of salt, and 1 teaspoon of vanilla extract. Mix on low speed until the dough comes together and forms a soft ball, about 2–3 minutes. The dough should be slightly crumbly but hold its shape when pressed.
Step 4: Press the Dough into the Pan
Take the shortbread dough and evenly press it into the bottom of your prepared pan. Use your hands or the back of a measuring cup to make sure it’s firm and level. To prevent bubbling during baking, prick the surface with a fork. This will allow steam to escape and help achieve that delightful texture.
Step 5: Bake the Shortbread Base
Position the pan in your preheated oven and bake for 20–22 minutes, or until you see the edges turn a light golden brown. Your kitchen will fill with a lovely buttery aroma, signaling it’s almost ready. Once baked, remove the pan from the oven and let it cool completely on a wire rack.
Step 6: Prepare the Caramel Layer
In a medium saucepan, combine 1 cup of sweetened condensed milk, 0.5 cup of packed light brown sugar, 0.5 cup of unsalted butter, 2 tablespoons of light corn syrup, and 0.25 teaspoon of salt. Over medium heat, stir the mixture continuously for about 8–10 minutes until it thickens and turns a rich golden color.
Step 7: Add Vanilla and Layer the Caramel
When your caramel has thickened, remove the saucepan from the heat and stir in 0.5 teaspoon of vanilla extract. Pour this luscious caramel over the cooled shortbread base, using a spatula to spread it evenly. This rich layer adds the indulgent characteristic that makes Millionaire’s Shortbread so special.
Step 8: Chill the Caramel Layer
Place the pan in the fridge and chill for at least 1 hour, allowing the caramel to set properly. This step is crucial for achieving clean layers when you cut into your Millionaire’s Shortbread later. The cooling time also enhances the flavors, creating a delightful treat.
Step 9: Melt the Chocolate Topping
To make the ganache, melt 1 cup of semi-sweet or dark chocolate chips with 2 tablespoons of heavy cream in a microwave or a double boiler over low heat. Stir until the mixture is smooth and glossy. This rich chocolate topping will beautifully complement the caramel layer below.
Step 10: Spread the Chocolate and Chill Again
Once melted, pour the smooth chocolate mixture over the chilled caramel layer. Use a spatula to spread it into an even layer, ensuring complete coverage. Return the pan to the fridge for at least another hour, allowing the chocolate to set completely without any sticky residue.
Step 11: Slice and Serve
After chilling, carefully remove your Millionaire’s Shortbread from the pan using the parchment overhang. Use a hot knife to slice it into 16 neat squares for a clean presentation. This method helps achieve crisp edges, making your creation even more appealing.
Step 12: Garnish and Enjoy
If desired, sprinkle your Millionaire’s Shortbread with flaky sea salt or dust with powdered sugar for a touch of elegance. These finishing touches not only enhance the visual appeal but also add contrast to the sweet layers. Serve immediately or share with friends and family for an indulgent treat that everyone will love!
Make Ahead Options
These Millionaire’s Shortbread bars are perfect for meal prep!

When you're ready to enjoy, melt the chocolate topping and pour it over the set caramel, giving it another chill for at least an hour. Rest assured, these steps will assure you get that same delicious taste and texture, saving you time for any busy weeknight or gathering!

Expert Tips for Millionaire's Shortbread
