Step‑by‑Step Instructions for Millionaire Shortbread Bars
Step 1: Prep the Oven and Pan
Preheat your oven to 350°F (175°C). While the oven warms, line an 8×8-inch baking pan with parchment paper, ensuring it hangs over the edges for easy removal later. This quick prep will save you from any messy cleanup and help achieve perfectly baked Millionaire Shortbread Bars.
Step 2: Make the Shortbread Base
In a large mixing bowl, cream together 1 cup of softened unsalted butter with 0.5 cup of granulated sugar until light and fluffy, about 3–5 minutes. Stir in 1 tsp of vanilla extract, then gently incorporate 2 cups of all-purpose flour and 0.25 tsp of salt until the dough forms. Press the mixture evenly into your prepared baking pan, smoothing the surface before baking for 18–20 minutes until golden brown.
Step 3: Prepare the Caramel Layer
In a medium saucepan, combine 0.5 cup of brown sugar, 14 oz of sweetened condensed milk, 0.25 cup of light corn syrup, and 1 cup of unsalted butter. Cook on medium heat while stirring continuously for about 8–10 minutes. The caramel should become thickened and golden, bubbling gently without boiling over. This rich caramel layer will be the heart of your Millionaire Shortbread Bars!
Step 4: Assemble Caramel Layer
Once your shortbread base has cooled completely, carefully pour the warm caramel mixture over it. Use a spatula to spread the caramel evenly across the shortbread, ensuring every corner is covered. Chill the assembled bars in the refrigerator for at least 30 minutes, allowing the caramel to set properly before you add the luscious chocolate layer.
Step 5: Finish with Chocolate Layer
While the caramel chills, melt 8 oz of chopped semisweet or milk chocolate in a microwave or double boiler. If desired, stir in 1 tbsp of butter or cream for added smoothness. Once melted, pour the chocolate over the chilled caramel, spreading it evenly with a spatula to create a beautiful, shiny top layer. Chill for another 1–2 hours until the chocolate is firm.
Step 6: Slice and Serve
After chilling, remove your Millionaire Shortbread Bars from the pan using the parchment paper overhang. Transfer to a cutting board and slice into squares or rectangles based on your preference. Use a warm knife to ensure clean cuts, and serve them at your next gathering or simply enjoy as a delightful treat!

Millionaire Shortbread Bars Recipe FAQs
How do I choose the right ripeness for the ingredients?
Absolutely! When selecting your butter, it should be softened but not melted—room temperature is ideal. For your caramel layer, the brown sugar should be soft and clump-free to ensure it incorporates well. It’s important that your sweetened condensed milk is fresh, so check the expiration date to ensure the best creamy texture!
What is the best way to store Millionaire Shortbread Bars?
Very! To store your Millionaire Shortbread Bars, keep them in an airtight container in the refrigerator for up to one week. If you want to save them for longer, wrap each bar individually in plastic wrap and place in a freezer-safe container for up to two months. This method helps preserve their fresh flavors and textures beautifully!
Can I freeze Millionaire Shortbread Bars?
Absolutely! For freezing, individually wrap each cooled bar with plastic wrap and place them in a freezer-safe container or bag. They can be frozen for up to two months. When you want to enjoy them again, simply transfer them to the fridge to thaw for a few hours, allowing the texture to remain delightful.
What if my caramel layer is grainy?
When making the caramel layer, constant stirring is key! If your caramel gets grainy, it may have boiled too quickly. To avoid this, make sure to cook on medium heat without rushing, stirring continuously until it thickens to a smooth consistency. If it still turns grainy, try reheating it gently on low heat and stirring continuously until it melts back into a smoother state.
Are there any dietary considerations I should keep in mind?
Absolutely! If you have dietary restrictions, there are some easy substitutions you can make. For a dairy-free version, use dairy-free margarine instead of butter, and opt for a dairy-free chocolate for the topping. If someone has gluten sensitivities, use gluten-free all-purpose flour in the shortbread base. Always double-check ingredient labels to ensure they meet dietary needs!
How long will these bars last?
Your Millionaire Shortbread Bars will stay fresh when stored properly. In the refrigerator, they’ll be good for up to one week. However, if you’ve frozen them, you can enjoy these decadent treats for up to two months, making them perfect for meal prep or keeping on hand for when those sweet cravings hit!
